Japanese, In Japan’s National Parks, in several cases, visitors are asked to pay fees because of insufficient budgets to conserve the natural environment and maintain facilities. Although the introduction of entrance fees has been frequently discussed at council meetings, it has yet to be established in the natural park system. However, according to a survey conducted in FY2023, 127 cases of entrance fees, fundraising by local governments and the private sector, and efforts to create an appropriate cycle between conservation and utilization were identified in national parks nationwide, and the number has been increasing annually. This study analyzed the circumstances of the discussions, introduced cases in Japan, and examined prospects based on discussions on user payments in Japan and abroad. To introduce user payments, managers should clarify the projects that are affected by budget shortfalls, consider cost sharing between public funds and visitor payments, and create a system that considers fairness. However, the most crucial aspect is building consensus with local stakeholders based on the results of the preliminary surveys. This collaborative approach is key to the successful implementation of user payments. Prior publicity, reliable and transparent systems, and
monitoring should accompany the system’s operation.

Influence of agricultural experiences on attachment and conservational attitude toward agricultural landscape and understanding farmland amenity
HAYASHI Kazusa, AIKOH Tetsuya
Journal of The Japanese Institute of Landscape Architecture, 84, 5, 571, 574, Japanese Institute of Landscape Architecture, 2021, [Peer-reviewed]
Japanese,

At present, decreasing farmland due to the shortages of farmers and the devastation of agricultural landscape are becoming grave concerns. Farmland serves several multifaceted functions as a green space, and its conservation is therefore essential. In this study, we aim to elucidate the effects of various agricultural experiences on the perception of agricultural landscape. Accordingly, an interview of university students was conducted in the form of a survey. Attachment, awareness of conservation, and an understanding of the multifunctional role of farmland itself are some of the aspects that were interviewed. To reveal the effects of agricultural experiences beyond a single day's interaction, lifetime experiences were targeted in this research. Several agriculture-based categories were extracted from individuals' experiences using text analysis. It was found that agricultural experiences positively affected the perception of farmland, suggesting that the types of landscapes that give rise to feelings of attachment differ depending on the individual's own categories of experiences. Additionally, it was suggested that when these experiences were accompanied by knowledge acquisition, the understanding of farmland amenity was also positively influenced.

How resource type and access fee collection method influence visitors'resistance to pay entry fees at sightseeing destinations
GOKITA Reiko, AIKO Tetsuya
Journal of The Japanese Institute of Landscape Architecture, 82, 5, 579‐582, 582, Japanese Institute of Landscape Architecture, 29 Mar. 2019, [Peer-reviewed]
Japanese,

Various natural areas are planning to institute or have already instituted a range of entry fees to enhance the experience of visitors. However, these areas still constitute a minority. Therefore, we conducted a questionnaire survey to analyze visitors'resistance to pay entry fees depending upon the resource type and difference in the fee collection method used. Regarding the type of resource, we found that resistance to pay an entry fee for a natural area was higher on average than an admission charge to access a public exhibition facility or cultural heritage. Desirable fee collection methods varied according to the resource type and aversion to paying fees for using facilities in natural areas and entering mountain areas was relatively high. In natural areas and mountain areas, attitudes toward payment were influenced by how frequently respondents to such areas visited natural areas as well as their intent to visit in the future. Those who visited natural areas frequently and intended to visit again were least resistant to paying fees. Based on the above, we conclude that if users are to be made to bear costs, charging them according to the type of resource would provoke the lowest possible resistance.

MITARAI Yozo, AIKOH Tetsuya, KOIKE Yasuhiko
Landscape Research Japan Online, 9, 0, 33, 38, Japanese Institute of Landscape Architecture, 2016, [Peer-reviewed]
Japanese, Nowadays, there are a number of citizens engaged in the community greenings by various kinds of flowers on an individual basis as well as on a group basis. In the case of Sapporo city, the municipal government supports both individuals and groups. In this study, we conducted the questionnaire survey with citizens, engaged in community greening in Sapporo city, to reveal the attitudes shown by two types of participants; one is on an individual basis and the other is both on an individual and a group basis. As a results, it appeared that there were some differences in the motivations between these two types of participants. More particularly, those engaged on an individual basis have much stronger motivations for "recreating themselves" and "growing flowers" than those engaged both on an individual and a group basis. On the other hand, both these two types of participants faced technical problems in horticultural areas. In addition, we found that about 60% of participants who engaged on an individual basis were willing to grow flowers in public spaces. In order to promote these activities more effectively, it is important to take advantage of coalitions across these two types of participants.

Japanese, Visitor monitoring is the essential management effort to make planning and management reasonable in national parks. Exact visitor statistics make managers possible to evaluate effectiveness of current management practices and facilities, and to predict future trends and demands to the park. In this study, we asked park managers to answer the current status and problems regarding with visitor monitoring which includes counting number of visitors and visitor survey. As the results, visitor counting and visitor survey have been conducted in most parks. Park managers recognized the importance and necessity of visitor monitoring. Nevertheless, they are concerned about the lack of budget and staff, and the reliability of monitoring methods. It is considered that standardized monitoring method and devices should be distributed, and sufficient budget and personnel training are necessary.

Relationship among Mountaion National Parks visitors' impressions, satisfaction, loyalty and psychological benefit
GOKITA Reiko, AIKO Tetsuya
Journal of The Japanese Institute of Landscape Architecture, 78, 5, 533, 538, Japanese Institute of Landscape Architecture, 2015, [Peer-reviewed]
Japanese, The principal role of National Parks are providing unusual scenery and recreation opportunity and conserving biodiversity. Promoting utilization of them also contributes to visitors' health and culture of our society. Visiting parks might make a lasting impression on visitors, and then satisfied visitors could affirm loyalty to parks and get psychological benefits. There have been less investigations regarding with the psychological benefits of National Parks in Japan. Thus, we conducted a questionnaire surveys at four popular Mountaion National Parks in Japan, Shiretoko, Nikko, Kamikochi, and Tateyama, to identify the relationship among visitors' impressions, satisfaction, loyalty and benefit. As a result, "nature appreciation," "enriching the mind," and "environmental awareness and understanding" are considered as great benefits due to visiting parks. Types of benefits are different by activities visitors attended. We also found the significant relationship between impression and satisfaction or benefit. The benefit has larger influence on their willingness to revisit and recommendations to others than satisfaction. Promoting National Parks utilization should pay attention to offering impressive experience in parks and the effect on visitors' loyalty.

MITARAI Yozo, AIKOH Tetsuya, KOIKE Yasuhiko
Landscape Research Japan Online, 7, 0, 41, 47, Japanese Institute of Landscape Architecture, 2014, [Peer-reviewed]
Japanese, Citizens living in urban areas are increasingly interested in participating in their community activities. As a part of their community activities, there are a lot of citizen groups engaged in horticultural volunteer activities in their neighborhoods. In this study, we conducted a questionnaire survey with participants of 18 citizen group which taking care of flowers in Sapporo city to examine their attitudes, especially their motivations and problems. As the result, it seemed that participants engaged in their activities with four motivations; one is to make their life worth living, the second is to contribute to their neighborhoods, the third is to communicate with other members and the forth is to growing flowers. Furthermore, participants could be divided into four clusters based on these four motivations, and each four clusters contained participants who belonged to several kinds of volunteer groups which have different purpose. On conclusion, it appeared that volunteer groups own several participants who have several kinds of motivations for the horticultural volunteer activities. In order to promote these activities, it is necessary to understand each participant's consideration and offer practical support to them.

Journal of Forest Economics, 60, 1, 14, 21, The Japanese Forest Economic Society, 2014, [Peer-reviewed], [Lead author]
Japanese, The Japanese National Park System currently faces problems with biodiversity conservation, overuse control, and collaborative management. This paper examines issues in park planning and the management of Japanese National Parks, using the case study of the trail maintenance guideline and the management of other facilities in Daisetsuzan National Park, Central Hokkaido, Japan. We found limited recognition of the trail maintenance guideline, a lack of social scientific data, a lack of facility-development standards and risk management, concerning about management of human resources and budget, and little discussion of fees. The park-planning process should include zoning of visitor experiences and should introduce the concept of carrying capacity. We also pointed out the need for revision of the current zoning system, which has been controlled by the intentions of landowners, to allow biodiversity conservation and to control overuse, and the necessity of social scientific monitoring and human resource development based on the social sciences.

MITARAI Yozo, AIKOH Tetsuya, KOIKE Yasuhiko
Journal of The Japanese Institute of Landscape Architecture, 76, 5, 743, 748, Japanese Institute of Landscape Architecture, 2013
Japanese, In these days, citizens living in urban areas are increasingly interested in developing their communities. As a part of the process of their community developments, there are various kinds of citizen groups engaged in horticultural volunteer activities in public spaces such as urban parks, open spaces along sidewalks and several public facilities. In this study, we conducted interviews with each leader of 20 citizen groups which taking care of flowers in Sapporo city to reveal the attitudes of their groups. In the process of this research, we focused on the difference of places where these volunteer activities were being conducted and the difference of relationships with neighbors. As the result, it appeared that 20 citizen groups were classified into four categories from two aspects whether they are conducting planting and maintaining flowers at sidewalks or neighboring flowerbeds, and they work cooperating with other neighbor volunteer groups. Each four categories have different motivations or issues relating to horticultural volunteer activities. In order to take measures to address each issue, it is necessary to build coalitions across several volunteer groups and community groups.

AIKOH Tetsuya, KAWAGUCHI Keisuke
Journal of The Japanese Institute of Landscape Architecture, 76, 5, 703, 706, Japanese Institute of Landscape Architecture, 2013
Japanese, Knowing the factors considered by hikers in selecting their entrance and routes can be helpful for mountainous natural park managers. Mt. Tomuraushi in Daisetsuzan National Park used to be a remote destination that required hikers to make overnight trips to reach the summit. With easier access, there has been a recent increase in day trip hikers. This increase has raised certain concerns, such as soil erosion on the visitor trails, trampling of vegetation, and extension of bare grounds around campsites. We conducted questionnaire survey on hikers' route selection and their reasons for choosing a specific route and trailhead to Mt. Tomuraushi. The results showed that hikers placed much value on scenery, availability of natural resources, and access and convenience of each route and trailhead. Important factors included conveniences, walkability and good scenery. More experienced hikers were found to be more likely to choose less convenient and less crowded trailheads than less experienced hikers.

Landscape Research Japan Online, 5, 0, 96, 103, Japanese Institute of Landscape Architecture, 2012
English, In order to balance the conservation of landscape and the promotion of recreational use, it is necessary to investigate the geographical characteristics of natural and recreational resources, and to apply rational planning process. In this study, we examined the zoning method using the geographical information system in Shikotsu Jozankei Area of Shikotsu Toya National Park, Japan. Forest compartments were ranked by five conservation importance indexes (vegetation naturalness, vegetation diversity, special plant community, geological formation and natural phenomenon) and four recreational usability indexes (slope, accessibility, distance from facility and viewshed). Then compartments were grouped into five clusters by the nonhierarchical cluster analysis. Comparison with current zoning in the area showed us similarities and some discrepancies. Some areas as ranked higher conservation values have been zoned into Ordinary areas which are designated as the least important area.

Japanese, The aims of this study were to analyze the data of accidents during 1989-2008 in the climbing at Mt. Fuji which extends over both prefecture of Yamanashi and Shizuoka in Japan and to clarify the characteristics of the accidents according to four main routes. In addition to those, authors tried to grasp the regional activities and management system to promote safe climbing in Yoshida route as a case study and considered risk management and planning of climbing. Analysis of a data set of accidents collected by prefectural police and interview with relevant people were employed. As a result, it was found that many accidents occurred at 7th and 8th steps at the mountain on the whole. With distinction of routes, there were more fall accidents in Yoshida and Fujinomiya routes and more lost climbers in Subashiri and Gotenba routes than the others respectively. In view of the results, it was suggested that it is necessary to organize information based on the characteristics of places and causes of accidents before providing it to climbers.

Japanese, Canoe tourists' crowding perceptions have been examined by means of actual experience and visual approach based on photomontage simulations in Gesashi River, Okinawa. The more actual use levels increased, the more canoe tourists felt crowded, and the less tourists were satisfied. Acceptable use levels in Gesashi River were estimated based on the answers of canoe tourists, canoe tour-guides, and people related to tourism. The results showed the differences among groups, canoe tour-guides ranked the highest acceptance for canoes in the river. As the results, the examination of canoe tourists' crowding perceptions was valid approach for canoe-tourism destination management. The various viewpoints of stakeholders should be considered to make the agreement regarding the definition of social carrying capacity.

Relationship Between the National Park Plan and the National Forest Plan in Shikotsu-Toya National Park
AIKOH Tetsuya, TOMIDOKORO Yasuko
Journal of The Japanese Institute of Landscape Architecture, 73, 5, 505, 508, Japanese Institute of Landscape Architecture, 2010
Japanese, In Japanese national parks,the designation of a park and its zoning boundaries is influenced by land ownership. There has been criticism that zoning is influenced by timber production or other commercial activities. We examined the relationship between the national park plan and national forest plan in the Shikotsu-Jozankei area in Shikotsu-Toya National Park. We overlaid the national forest management plan map with the park plan map using a GIS. We found that half of the park boundaries have commonality with a national forest unit and 36% with municipal boundaries. The special protection zone and special zone I of the national park plan are similar to the Protection Forest in a national forest. Special zone II is similar to the Recreation Forest in a national forest. National forest functional zones have many similarities with national park zoning. These results clarified the significant effect of a national forest plan on the definition of national park zoning.

Japanese, Green spaces in residential areas have various functions, such as for recreational activities, making the place beautiful and so on. In this research, we investigated the economic effect of green spaces on the land prices in the residential area of Sapporo City, through an environmental economics technique. Factors contributing to the formation of the posted land price for the residential area in Sapporo City were identified by the hedonic approach. Results showed that the size of the nearest park or the ratio of green space surrounding the land contributed to the formation of the land price in addition to the area, shape, zoning and the access conditions such as the distance to the closest station and school. Therefore, the building and conservation of green spaces seems to be one clear option for raising the asset value of the residential area.

Journal of The Japanese Institute of Landscape Architecture, 70, 5, 515, 518, The Japanese Institute of Landscape Architecture, 30 Mar. 2007
Japanese, Recreational use of dog walkers in urban open space is one of the concerned issues by managers. There are complains from other visitors, such as unpicked feces, unleashed dogs, or threatening children. In this study, three different types of urban open space were chosen, then dog walkers’ behaviors and their attitudes were surveyed. In the public park, dog walkers and other visitors were sharing same space and time. In the dog run, dog walkers took their dogs a few times a week, and let them run freely. In the exterior of one public facility, dog walkers took their dogs frequently to let them run freely. Consequently, this public space was used as if a dog run. To prevent the conflict between dog walkers and other visitors, manner training and some rules are needed, and besides various types of open spaces should be offered.

Japanese, Trail degradations have been found in popular mountainous natural parks in Japan. For maintenance of trails, managers should pay attention to the attitudes of hikers and stakeholders, and they should get the consensus for the ideal maintenance method of trails with hikers and concerned stakeholders. The method that demonstrates projected trail maintenance method is needed. In this paper, we compared the hikers' evaluation of trail condition and the image of trail maintenance between on-site survey and mail-back survey at Daisetsuzan National Park, Japan. We also applied photo-montage method to evaluate projected trail maintenance by stakeholders using conjoint analysis. There were little differences between on-site hikers evaluation and mail-back evaluation. The results also didn't show any differences between labeled photos and unlabeled photos. The results of conjoint analysis showed that stakeholders considered the importance of limit of use level less than trail surface maintenance. Stakeholders preferred boardwalk at Susoaidaira where are flat and muddy area.

Attitudes of Hikers and Stakeholders about Trail Maintenance at Mt. Rishirisan
AIKOH Tetsuya, NORITOMI Tsuyoshi
Journal of The Japanese Institute of Landscape Architecture, 68, 5, 743, 746, The Japanese Institute of Landscape Architecture, 31 Mar. 2005
Japanese, Trail degradations have been found in most mountainous natural parks in Japan. For maintenance of trails, managers should pay attention to the attitudes of visitors and stakeholders, and they should get the consensus for the ideal maintenance method of trails with visitors and concerned stakeholders. The method that demonstrates projected trail maintenance measure is needed. Moreover managers should understand that the attitudes of hikers and stakeholders about trail maintenance are not always similar. In this paper, we applied photo-montage method to evaluate projected trail maintenance, and analyzed the differences of evaluations of hikers and stakeholders at Mt. Rishirisan in Rishiri Rebun Sarobetsu National Park, Japan. Stakeholders recognized trail impacts, and they felt necessity of some measures more than hikers did, especially around the summit of Mt. Rishirisan. Stakeholders and hikers evaluated the photograph which has steps with logs higher than other photographs. Hikers and stakeholders gave priority over the protection of vegetations and soils around trails. Stakeholders wanted the slight trail maintenance, the PR of the place where trails were degraded and the council which public administrators and local people would discuss the management of the mountain.

Japanese, The demand to provide access to parks and universal designed parks are increasing. This paper aimed to find the wheel chair visitors' demand for parks, and to examine the physical factors preventing them from visiting parks. The frequency of their visitations to parks are less than other recreations. They demand the parks which has special facilities for disabilities and gentle slope trails. Also, we surveyed the running slope, width, and surface of trails in three large city parks, and evaluated the accessibility of each trail segments by GIS. The results showed that either running slope or surface made passing difficult, and the lack of continuity of each segments prevented access of wheel chair visitors.

In some natural parks, the increase of personal water crafts seems to cause the impact on their natural resources and visitors' experience. Some parks administrators have realized such problems, and they have practiced several control methods through law enforcement, by-laws and self-imposed rule. We gathered information about the method and process of some use adjustment, and interviewed related officials and personel. Results suggests the necessity of close connection among stakeholders, and the importance of public participation.

This research aimed to consider about the Personal Watercraft use management on Japanese National Park Areas, referring to the U.S. National Park Service Cases and their surroundings. NPS has prohibited the PWC use in their areas except some National Park unit. The Personal Watercraft Industry Association claimed that the regulations were unreasonable and unsupported by evidence and arbitrary, but these trends were supported with the NPS missions. There are not only PWC use regulations, but strong enforcement of boating and navigation law and mandatory boating safety education for PWC users. They were necessity for Japanese PWC users.

English, Recently there have been examples of citizen participation in street flower planting and maintenance in many cities around Hokkaido. Flowers planted along the pavement are to be seen in many residential areas of Sapporo. In order to understand residents' attitudes towards street flowers, a questionnaire was delivered in the Satsunae area of Higashi Naebo, Sapporo, where flowers had been planted in the streets.
The results showed strong agreement on the aesthetical contribution of flowers to the streetscape. Factor analysis of the items related to street flowers revealed the following four factors:‘effort to maintain’, ‘socio-environmental’, ‘aesthetic value/closeness to nature’ and ‘privacy issues’. Cluster analysis based on factor scores divided the sample into three groups according their attitudes to street flowers. People in Cluster 1 appeared to have negative attitudes as a whole. Representatives of Cluster 2, who were mostly in their 40s and 50s, could be named as the ‘socially oriented’ group whereas those in Cluster 3 appeared to be the aesthetically appreciative group.

Journal of The Japanese Institute of Landscape Architecture, 65, 5, 669, 672, The Japanese Institute of Landscape Architecture, 30 Mar. 2002
Japanese, In order to define the social carrying capacity in National Parks, it is necessary to survey visitors' crowding perceptions and acceptable limits of encounters with other visitors. However, the numerical approach, which consists ofasking respondents about an acceptable number of other visitors, has several shortcomings. In this study, a visual approach, based on photomontage simulations, was applied to measure visitors' crowding perception and acceptable limit of encounters in the Sugatami area, in Daisetsuzan National Park, Hokkaido. The results are summarized as follows:
1) the response rate of acceptable limits of encounters estimated by a visual approach was about twice the rate investigated by the numerical approach used in previous studies. Therefore the visual approach could be accepted as effective, especially in high-use areas.
2) although visitors' crowding perceptions heightened with the increase of visitors in the photo simulations, this relationship was not always consistent. As for the results, more thorough examination about location of visitors and scene composition in the photo simulations might be necessary.

JILA Annual Scientific Research Meeting Abstracts, 65, 0, 60, 60, Japanese Institute of Landscape Architecture, 2002
Japanese, Summary: The social and ecological impacts caused by the increased number of visitors in the mountains, many of which designated as National Parks, should be considered. Though there are mountaineers involved with the management of some areas, but the structure of their organizations, the nature of their activities as well as the problems they face are unknown. In order to obtain information about this, 225 alpine clubs in Hokkaido were surveyed by a questionnaire, the response rate of which was 61.3%. It became clear that many of the alpine clubs maintain and keep tidy trails and huts, protect land, train climbers and attitudes, and arrange climbing meetings. While involved in management activities, these clubs, regional federations of alpine clubs and volunteer organizations, have played an important role in liaising with other institutions, such as local authorities and foresters. Among the difficulties these clubs had faced were the lack of volunteers, various obstacles as well as the lack of established communications between them and the administration. It could be concluded that providing administrative support and working in collaboration with these clubs could help to obtain a successful management of the mountain areas.

JILA Annual Scientific Research Meeting Abstracts, 65, 0, 56, 56, Japanese Institute of Landscape Architecture, 2002
Japanese, Comparison of coastal landscape resources and land-uses on Hokkaido were discussed in this paper. Conservation of landscape resources, particularly natural coasts, were disturbed by their land-uses. Comparison of the changes in natural coastal areas belonging to natural parks versus those not belonging to natural parks, revealed almost no changes in the former but decreases in the latter, and in particular decreases of sandy gravel coasts. This could be explained by the fact that the management level of coastal areas belonging to natural parks is not as intensive as of those not belonging to. Since the proportion of the sandy gravel coasts in natural park areas has the lowest percentage compared to cliff and rock formations, their preservation and management should be considered.

Perceived Crowding, Acceptable Limits of Econunters, Coping Behavior at Kamuiwakka in Shiretoko National Park
KOBAYASHI Akihiro, AIKOH Tetsuya
Journal of The Japanese Institute of Landscape Architecture, 64, 5, 723, 728, The Japanese Institute of Landscape Architecture, 30 Mar. 2001
Japanese, My concern here is whether indicators and standards of negative changes in recreation experience are effective in response to the degree of the deterioration in social condition. The question is to have an insight into subjects on grasping the level of encounters, crowding perception, acceptable limits of encounters and coping behavior with congestion under traffic control. This is a case study conducted at Kamuiwakka in Shiretoko National Park. Data of visitors' attitude were collected by a mail-back questionnaire survey on visitors. Visitors' behavior in Kamuiwakka River was recorded by videotape. As a result, user density and encounter level fluctuated in a shot time. The level of encounters could be estimated by the speed of visitors' walking, their route and time taken. The level of encounters of visitors affected crowding perception. Visitors' expectation toward Kamuiwakka, unpleasantness toward congestion and evaluation of traffic control management affected crowding perception more strongly. In spite of higher visitor density than last year, rate of unpleasantness of crowding was lower than last year. Rate of answering acceptable limits of encounters in the river was low. The degree of acceptable limits of encounters related to the attitude toward management of visitor control, but not related to the crowding perception and the level of encounters. Sensitive visitors of unpleasant condition induced by congestion had a tendency to actively select less denser timing to avoid congestion and shift their expectations or preference to reduce the discrepancy between desired and achieved outcomes. In conclusion, crowding perception was not sensitive indicator of congestion under higher density. Most of visitors in higher density did not have norms of limit of acceptable encounters. Considering rapid change of encounters and users' attitude toward high density, we had better prescribe the quality of recreational experience as the probability of occurrence of the conditions than statistic number of entry.

User Evaluation of Coastal Landscape of the Ishikari Coast
MATSUSHIMA Hajime, ASAKAWA Shoichiro, AIKOH Tetsuya
Journal of The Japanese Institute of Landscape Architecture, 63, 5, 789, 794, The Japanese Institute of Landscape Architecture, 30 Mar. 2000
Japanese, As coastal use increases, various problems concerning the coastal environment and user conflict have happened. To grasp these coastal user perceptions about coastal environments, landscapes and other users is helpful for management of these areas. The oral survey of coastal users was conducted at Ishikari Coast, Hokkaido in the summer of 1999. In this survey, coastal users were asked to evaluate 18 photos of coastal landscapes, to mention open-ended descriptions associated with ‘Coast’ and ‘Ishikari Coast’ and to talk about their knowledge and thought for coastal environment and management. These results were summarized as follows:
1) Use of place selection was dependent on their activities and management of these places.
2)‘Coast’ reminded users of objective images about the coast or activities pertaining to them. The other, ‘Ishikari Coast’, reminded users of subjective features about this place or knowledge, they have.
3) User evaluation of coastal landscape and user thought about environment depended on their coastal activities. This tendency was especially negative concerning human impact, while most users preferred natural landscapes.

Profiles of subjects were less related to the evaluation. Furthermore, the preference score rose when sky, mountains, or farmland in the foreground existed in a picture. Video pictures were classified into four landscape types;(1) grass land slope, (2) near forest, (3) prospect and near farmland and (4)“prospect” or “relatively open scenery”. We inferred that people had a tendency to feel favorable when presented a sequence of open scenery. Conversely, they feel unfavorable when presented a sequence of closed scenery.

Japanese, In urban areas, private gardens' vegetation contributes to neighborhood environmental quality. Recently, People have expected increased wildlife habitat, improved streetscape, and others tool of community development. To consider these roles, it is important to investigate attitudes of residents regarding their gardens in Megurnino, Hokkaido. In order to understand residential perception and management, we carried out a questionnaire survey concerning vegetated flowers in front yards. The results are as follows. The strongest motivation of gardening is the act of planting. Other motivation factors include nonspecified, food production, and increase of family or neighborhood interaction. People wanted more knowledge about plants or gardening. The type of motive about gardening has influenced residents' perceptions, management, vegetation, and front yard flower arrangements.

Mountaineers' Acceptable Limits of Human Encounters and Manners, and their Coping Behavior
AIKOH Tetsuya, ASAKAWA Shoichiro
Journal of The Japanese Institute of Landscape Architecture, 63, 5, 619, 624, The Japanese Institute of Landscape Architecture, 30 Mar. 2000
Japanese, For defining social carrying capacity in recreational settings, it is necessary to ask visitors about their acceptable limit of encounters with other visitors. But their coping behavior may confound the reliability of that information. We examined the relationship between mountaineers' acceptable limit of encounters and their coping behavior. The survey was conducted at Daisetsuzan National Park from July to September in 1998. Mountaineers' acceptable limit of encounters with other visitors, acceptable limit of discourteous manners, their intention of coping behavior and their experience of coping behavior were acquired by a mail-back questionnaire. The results may be summarized as follows:
1) Mountaineers who were tolerant of encounters were older, traveled shorter distances, and were less able to recognize human impacts.
2) Some mountaineers avoided encounters with others by coping behaviors such as intra-site displacement. When the number of encounters exceeds the acceptable limit, they tend to change their experience definitions to what they expect of more crowded conditions, or move to a less crowded area, tent site or season.

Japanese, As a result of increasing recreational use, various impacts on natural environment and visitor experiences were observed in natural parks. Information about visitors' perceptions of human impact is useful in managing natural parks. The survey was conducted at Daisetsuzan National Park from July to September in 1998. Mountaineers' perceptions of human impact and attitudes to human waste disposal were acquired by a mail-back questionnaire. The results may be summarized as follows:
1) While mountaineers' perceptions of human impact varied, there was a general consensus concerning discomfort with human waste disposal, and the necessity of its management.
2) The difference in disposal methods of waste and attitude to human waste disposal varied according to gender, mode of travel and mountaineers' perception of human impact.

The purpose of this study is to understand the effects of view aspects in river landscape evaluation and to clarify the differences of cognitive constructs by use of the repertory grid technique. The results of quantification-I analysis showed that the view aspects affected evaluations. As the result of multi-dimensional scaling, background was recognized as a dimension which affected the evaluation of any view aspect, which corresponded to the results of the cluster analysis. Conversely, other dimensions which reflected differences of origin in image were recognized for each view aspect, and also correspondedto the results of the cluster analysis. Finally, it was clarified that cognitive constructs varied according to view aspects.

The Influence of Tent Setting on Visitors' Crowding Perception at Mountainous Campsite
AIKOH Tetsuya, ASAKAWA Shoichiro
Journal of The Japanese Institute of Landscape Architecture, 61, 5, 627, 630, The Japanese Institute of Landscape Architecture, 30 Mar. 1998
Japanese, Campsite is one of the most crowded site in mountainous recreation area. We examined the influence of tentsetting on visitors' crowding perception and uncomfortable factor at campsite in Daisetsuzan National Park. In 1995, 1996, we surveyed location oftents, unit area and interval of tents. Visitors' perception of other tents and other visitors, tolerable number of other tents and other visitors, crowding perception and uncomfortable factor were acquired by the questionnaire survey.
The results showed that increase of actual use level decreased unit area and interval of tents, and increased visitors' perceived use level, perceived crowding and number of uncomfortable factors. When actual use level exceeded tolerable use level reported by visitors, perceived crowding and number of uncomfortable factors were high significantly. The results demonstrate the usefulness of tolerable use level to establish carrying capacity for campsites.

Journal of The Japanese Institute of Landscape Architecture, 59, 5, 169, 172, The Japanese Institute of Landscape Architecture, 29 Mar. 1996
Japanese, Informations about visitor behavior and congestion are essential for management and planning in natural parks. In this paper, a computer model were applied to examine the congestion and behavior of visitors on natural trails in Daisetsuzan National Park. From outputs of this model validly represented a real system, it was showed that the number of encounters and visual encounters were relatively high on paths and observation platforms where there were many groups. In addition, the number of encounters may multiply on paths as the number of total groups increases. This model might be a useful tool for management and planning in natural parks.

Motivations and Expectations of Mountatineers in Relation to Choice of Area and Route in Daisetsuzan National Park
KOBAYASHI Akihiro, AIKOH Tetsuya
Journal of The Japanese Institute of Landscape Architecture, 58, 5, 213, 216, The Japanese Institute of Landscape Architecture, 31 Mar. 1995
Japanese, The present study examined the motivations and expectations of mountaineers in relation to the areas they visited and the routes they chose in Daisetsuzan National Park. The analysis was based on data obtained from a mail-back questionnaire survey.
This results showed that the route chosen depended on various factors such as the desire to commune with nature, the desire for solitude, relaxation, mental challenge and physical challenge, and that expectations and motivations for choosing various areas generally corresponded among visitors selecting similar routes. Expectations for each area varied among visitors selecting different routes, while those of visitors selecting a similar route varied during the course of the route. It was presumed that the choice of route was determined as a result of its suitability for providing the desired outcome and because of its availability in terms of limitations imposed by factors such as time, skills and physical strength. thus, route selection is viewed as instrumental behavior with the goal of harmonizing expected and actual outcomes.
A general trend toward high expectations for remote, more pristine areas was observed, whereas expectations were much lower in areas with developed facilities that were easily accessible to large numbers of people. It is thus concluded that development which alters nature in a national park diminishes the expectations and satisfaction of mountaineers who visit the park.

Mountaineers' Acceptable Impact Levels of Encounter and Discourteous Manner in Daisetsuzan National Park
KOBAYASHI Akihiro, AIKOH Tetsuya
Journal of the Japanese Institute of Landscape Architects, 57, 5, 313, 318, The Japanese Institute of Landscape Architecture, 1993
Japanese, It is necessary to set standards for acceptable recreational impact levels for the assessment of National Park. The purposes of the present paper were to determine how much and what kind of recreational impact were acceptable for recreational settings and to clarify some variation of norms in different situations. Mountaineers in Daisetsuzan National Park were chosen for these purposes.
This analysis was based on the data from a questionnaire administered to mountaineers by mail-back survey. We asked the respondents to report “How much impact is tolerable before your experience becomes unpleasant?”. An “It doesn't matter to me” category was included for users unable to name a specific personal norm. The questions included four types of impact measurement: encounter level per day, encounter level at campsites, instance of discourteous manner per day and instance of discourteous manner at campsites and hats.
As a result, findings showed greater variation of norms and an increase in the percentage of “no respon se” to the higher density situation. The tolerance norms for “discourteous manner” were characterized by a few respondents tolerating a little impact. There was little variation between norms for “discourteous manner” in different situations. The tolerance norms for “encounter” were higher than those for “discourteous manner” and higher in the areas with higher use and more development. Response frequencies for each impact question were graphed, aggregating personal norms into a curve showing the full range of agreement levels.
In conclusion, the differences between norms in different situations support the usefulness of normative approach. It is noted that the usefulness of normative approach lies in their ability to characterize agreement about acceptable impact levels for particular recreation settings.

A Relationship between Number of Campers and Crowding Perception at Campsites in Daisetsuzan National Park

Japanese, Establishing carrying capacity requires investigation of the characteristics of visitors' crowding perception, various factors such as for examples, perceived number of other visitors, visitors' experiences, their expectation of density and significance of crowding.
This study examined the relationships of actual use levels, perceived use levels, desirable use levels and visitors' crowding perception at campsites in Daisetsuzan National Park. We examined the differences between desirable use levels and acceptable use levels. For these purposes, visitors' perceptions and views of use level were acquired by the questionnaire survey.
The subjects perceived lower use levels than actual use levels at high use levels. The results indicated that desirable use levels were stable to actual use levels. Therefore, it is apparent that an increase of actual use level increased the difference between actual or perceived use levels and desirable use levels. The increase of those difference increased crowding perception and decreased preference of density at campsites. Also it was revealed that desirable use levels were lower than acceptable use levels.

Japanese, The purposes of this paper were to examine how personal norms of mountaineers affected their evaluations of crowding, and to investigate the relationships among their evaluations of crowding and total evaluations of thier experiences.
Two campsites in Daisetsuzan National Park were choosen forthese purposes. Personal norms, evaluations of crowding and total evaluations were gained by questionnaire survey. Personal norms included motives of mountaineering, expectation of crowding and significance of crowding in their experiences at campsites. Evaluations of crowding at campsites included crowding perception and preference for actual situation. Total evaluations included evaluations of relaxational, solitary environment and multi-lateral satisfaction.
As the results, their significance of crowding affected crowding perception relating relaxational satisfaction and preference relating total satisfaction. Their motives seeking nature experience, quietness and peace of mind affected their significance of crowding. Besides, their motives seeking escape from others affected their expectation and significance of solitary environment, but did not affected their expectation and significance of crowding at campsites. Thus campsites were not likely to gratify mountaineers' needs of solitude.

Japanese, Increasing recreational use of natural park affects natural resources and visitor satisfaction. Study of carrying capacity in nature parks will be needed for a suitable management.
The purposes of this paper were to explore the relationships among visitor crowding, visitor per-ception of encounters with others and actual use levels and to grasp the effects of personal attributes on visitor crowding. As a case study, Daisetsuzan National Park was chosen for these purposes.
Actual use levels included visitor density, number of parties encountered and number of visitors encountered. Visitor perception of encounters and visitor crowding were gained by questionnaire survey to visitors on a trail segment.
The results showed that visitor crowding was more related to visitor perception of encounters than to actual use levels. It was suggested that the process of visitor perception of encounters and visitor crowding was affected by their previous experience of Daisetsuzan National Park.

Chubu-Sangaku National Park has been implementing the "North Alps Trail Program (tentative)" on a trial basis since 2021. In this study, based on this case study, we conducted a text-mining analysis using free description data collected from user questionnaires in order to grasp what points could be improved in the user burden system, based on opinions spontaneously expressed by users regarding user awareness of the cost burden for maintaining trails in national parks. As a result, a positive evaluation was confirmed for the entire initiative, and opinions on the issues and programs for maintaining the mountain trail could be classified into nine groups. In addition, it became clear that the words that appear differ depending on how well they are aware of the current issues., Center for Environmental Information Science, Japanese

Analysis of Seasonal Differences of Children's Urban Park Usage in Snow Cold District
SHIINO Akio, AIKOH Tetsuya, Landscape Research Japan Online, 7, 0, 148, 154, 2014
This paper aimed at clarifying the current circumstances and seasonal differences of children's outdoor plays, and analyzing the factors that affect their behaviors in snow cold district. As a result of questionnaire survey, 1,390 children responded effective answers, and following points were made clear: 1. Frequency and travel time from their own home to children's outdoor playground both felled-off in winter period, 2. Open spaces located close to children's own home were more frequently used as their playground in winter, 3. Parents' opinions about their children's outdoor play in winter affected the frequency of children's outdoor plays, 4. Changing patterns of children's urban park uses between summer and winter were not changed in a single uniform way, but changed into three typical types, such as Type I: use decreased in winter period, Type II: continually used through a whole year, and Type III: use increased in winter period., Japanese Institute of Landscape Architecture, Japanese

Current Status and Issues of Risk Management in the Oirase Stream Area, Towada-Hachimantai National Park, Japan : From the Viewpoints of Visitors' Preferences as Well as Management Practices

This paper aims to clarify the status and issues of risk management in the Oirase Stream Area (OSA). First of all, a visitor questionnaire was carried out in the OSA in October 2009. The respondents were asked to answer questions such as notion of self-responsibility for accidents. The survey showed that respondents could be divided into 4 groups with regard to risk preferences. While around 90% of respondents hoped more recreation facilities should be built for safety, a small portion of respondents agreed to the notion of self-responsibility even in case of the OSA. Furthermore, risk management practices in the OSA were investigated by taking interviews to public authorities. After an accident happened in the OSA in 2003, the public authorities more frequently conducted inspections of fallen trees and fallen branches in advance. Also the Aomori Prefecture signed the facility liability insurance. There, however, still exits potential risks such as inadequate infrastructure and ambiguous borders among stakeholders. More collaborative actions such as establishing a liaison council could be needed., The Japanese Forest Economic Society, Japanese

Relatioship between the national park plan and the national forest plan in Shikotsu-Toya National Park
AIKOH Tetsuya, TOMIDOKORO Yasuko, JILA Annual Scientific Research Meeting Abstracts, 2010, 0, 27, 27, 2010
In Japanese national parks, the designation of a park and its zoning boundaries is influenced by land ownership. There has been criticism that zoning is influenced by timber production or other commercial activities. We examined the relationship between the national park plan and national forest plan in the Shikotsu-Jozankei area in Shikotsu-Toya National Park. We overlaid the national forest management plan map with the park plan map using a GIS. We found that half of the park boundaries have commonality with a national forest unit and 36% with municipal boundaries. The special protection zone and special zone I of the national park plan are similar to the Protection Forest in a national forest. Special zone II is similar to the Recreation Forest in a national forest. National forest functional zones have many similarities with national park zoning. These results clarified the significant effect of a national forest plan on the definition of national park zoning., Japanese Institute of Landscape Architecture, Japanese

Analysis of Economical Effect of Green Spaces on Land Price in Residential Areas by Hedonic Approach
AIKOH Tetsuya, SAKIYAMA Naruko, SHOJI Yasushi, JILA Annual Scientific Research Meeting Abstracts, 2008, 0, 65, 65, 2008
Green spaces in residential areas have various functions, such as for recreational activities, making the place beautiful and so on. In this research, we investigated the economic effect of green spaces on the land prices in the residential area of Sapporo City, through an environmental economics technique. Factors contributing to the formation of the posted land price for the residential area in Sapporo City were identified by the hedonic approach. Results showed that the size of the nearest park or the ratio of green space surrounding the land contributed to the formation of the land price in addition to the area, shape, zoning and the access conditions such as the distance to the closest station and school. Therefore, the building and conservation of green spaces seems to be one clear option for raising the asset value of the residential area., Japanese Institute of Landscape Architecture, Japanese

Recreational use of dog walkers in urban open space is one of the concerned issues by managers. There are complains from other visitors, such as unpicked feces, unleashed dogs, or threatening children. In this study, three different types of urban open space were chosen, then dog walkers' behaviors and their attitudes were surveyed. In the public park, dog walkers and other visitors were sharing same space and time. In the dog run, dog walkers took their dogs a few times a week, and let them run freely. In the exterior of one public facility, dog walkers took their dogs frequently to let them run freely. Consequently, this public space was used as if a dog run. To prevent the conflict between dog walkers and other visitors, manner training and some rules are needed, and besides various types of open spaces should be offered., Japanese Institute of Landscape Architecture, Japanese

A Study on Evaluations of Trail Maintenance by Hikers and Stakeholders
Aikoh Tetsuya, Kobayashi Akihiro, Shoji Yasushi, Yamaki Kazushige, JILA Annual Scientific Research Meeting Abstracts, 2006, 0, 64, 64, 2006
Trail degradations have been found in popular mountainous natural parks in Japan. For maintenance of trails, managers should pay attention to the attitudes of hikers and stakeholders, and they should get the consensus for the ideal maintenance method of trails with hikers and concerned stakeholders. The method that demonstrates projected trail maintenance method is needed. In this paper, we compared the hikers' evaluation of trail condition and the image of trail maintenance between on-site survey and mail-back survey at Daisetsuzan National Park, Japan. We also applied photo-montage method to evaluate projected trail maintenance by stakeholders using conjoint analysis. There were little differences between on-site hikers evaluation and mail-back evaluation. The results also didn't show any differences between labeled photos and unlabeled photos. The results of conjoint analysis showed that stakeholders considered the importance of limit of use level less than trail surface maintenance. Stakeholders preferred boardwalk at Susoaidaira where are flat and muddy area., Japanese Institute of Landscape Architecture

Attitudes of Hikers and Stakeholders about Trail Maintenance at Mt.Rishirisan
Aikoh Tetsuya, Noritomi Tsuyoshi, JILA Annual Scientific Research Meeting Abstracts, 2005, 0, 54, 54, 2005
Trail degradations have been found in most mountainous natural parks in Japan. For maintenance of trails, managers should pay attention to the attitudes of visitors and stakeholders, and they should get the consensus for the ideal maintenance method of trails with visitors and concerned stakeholders. The method that demonstrates projected trail maintenance measure is needed. Moreover managers should understand that the attitudes of hikers and stakeholders about trail maintenance are not always similar. In this paper, we applied photo-montage method to evaluate projected trail maintenance, and analyzed the differences of evaluations of hikers and stakeholders at Mt. Rishirisan in Rishiri Rebun Sarobetsu National Park, Japan. Stakeholders recognized trail impacts, and they felt necessity of some measures more than hikers did, especially around the summit of Mt. Rishirisan. Stakeholders and hikers evaluated the photograph which has steps with logs higher than other photographs. Hikers and stakeholders gave priority over the protection of vegetations and soils around trails. Stakeholders wanted the slight trail maintenance, the PR of the place where trails were degraded and the council which public administrators and local people would discuss the management of the mountain., Japanese Institute of Landscape Architecture

On the Conservation of Coastal Area Scenic Resources in Hokkaido, Japan
MATSUSHIMA Hajime, ASAKAWA Shoichiro, AIKOH Tetsuya, Journal of The Japanese Institute of Landscape Architecture, 65, 5, 633, 636, 30 Mar. 2002
Comparison of coastal landscape resources and land-uses on Hokkaido were discussed in this paper. Conservation of landscape resources, particularly natural coasts, were disturbed by their land-uses. Comparison of the changes in natural coastal areas belonging to natural parks versus those not belonging to natural parks, revealed almost no changes in the former but decreases in the latter, and in particular decreases of sandy gravel coasts. This could be explained by the fact that the management level of coastal areas belonging to natural parks is not as intensive as of those not belonging to. Since the proportion of the sandy gravel coasts in natural park areas has the lowest percentage compared to cliff and rock formations, their preservation and management should be considered., The Japanese Institute of Landscape Architecture, Japanese

Mountain Area Management by Alpine Clubs in Hokkaido, Japan
NAKANE Kazuyuki, AIKOH Tetsuya, ASAKAWA Shoichiro, Journal of The Japanese Institute of Landscape Architecture, 65, 5, 653, 658, 30 Mar. 2002
Summary: The social and ecological impacts caused by the increased number of visitors in the mountains, many of which designated as National Parks, should be considered. Though there are mountaineers involved with the management of some areas, but the structure of their organizations, the nature of their activities as well as the problems they face are unknown. In order to obtain information about this, 225 alpine clubs in Hokkaido were surveyed by a questionnaire, the response rate of which was 61.3%. It became clear that many of the alpine clubs maintain and keep tidy trails and huts, protect land, train climbers and attitudes, and arrange climbing meetings. While involved in management activities, these clubs, regional federations of alpine clubs and volunteer organizations, have played an important role in liaising with other institutions, such as local authorities and foresters. Among the difficulties these clubs had faced were the lack of volunteers, various obstacles as well as the lack of established communications between them and the administration. It could be concluded that providing administrative support and working in collaboration with these clubs could help to obtain a successful management of the mountain areas., The Japanese Institute of Landscape Architecture, Japanese

ATTITUDES TOWARDS STREET FLOWERS IN SAPPORO
Todorova Assenna, Asakawa Shoichiro, Aikoh Tetsuya
JILA Annual Scientific Research Meeting Abstracts, 2002
Recently there have been examples of citizen participation in street flower planting and maintenance in many cities around Hokkaido. Flowers planted along the pavement are to be seen in many residential areas of Sapporo. In order to understand residents’ attitudes towards street flowers, a questionnaire was delivered in the Satsunae area of Higashi Naebo, Sapporo, where flowers had been planted in the streets. The results showed strong agreement on the aesthetical contribution of flowers to the streetscape. Factor analysis of the items related to street flowers revealed the following four factors: ‘effort to maintain’, ‘socio-environmental’, ‘aesthetic value/closeness to nature’ and ‘privacy issues’. Cluster analysis based on factor scores divided the sample into three groups according their attitudes to street flowers. People in Cluster 1 appeared to have negative attitudes as a whole. Representatives of Cluster 2, who were mostly in their 40s and 50s, could be named as the ‘socially oriented’ group whereas those in Cluster 3 appeared to be the aesthetically appreciative group.

JILA Annual Scientific Research Meeting Abstracts, 2002
Comparison of coastal landscape resources and land-uses on Hokkaido were discussed in this paper. Conservation of landscape resources, particularly natural coasts, were disturbed by their land-uses. Comparison of the changes in natural coastal areas belonging to natural parks versus those not belonging to natural parks, revealed almost no changes in the former but decreases in the latter, and in particular decreases of sandy gravel coasts. This could be explained by the fact that the management level of coastal areas belonging to natural parks is not as intensive as of those not belonging to. Since the proportion of the sandy gravel coasts in natural park areas has the lowest percentage compared to cliff and rock formations, their preservation and management should be considered.

JILA Annual Scientific Research Meeting Abstracts, 2002
今日多くの山岳自然公園では、登山利用に伴う自然環境、及び利用者への影響が問題となり対策が求められている。各地から登山者による管理活動が報告されているが、その内容や組織体制、活動に伴う課題は明らかでない。本研究では北海道の山岳会を対象に郵送でアンケート調査を行い、その結果、登山道や山小屋等施設の清掃や修復、監視、技術指導、登山会の開催等の活動が明らかになった。また、山岳会、地区連盟、ボランティア団体が、山岳地管理の組織化と対外的な応対を行っていた事例がみられた。一方、参加者不足、活動の負担、連携不足が問題として挙げられ、行政による支援と制度上の位置付けが必要と考えられた。

本研究の目的は、絶滅危惧種を「見せること」が「守る」ことにつながる方法を創出することである。シマフクロウとコウノトリとトキという異なる絶滅危惧種を対象に、対象種や生息域への影響といった「生態学的問題」と協働と合意形成という「社会学的問題」を同時に考える学際的アプローチにより、絶滅危惧種の保全と利用サイクルの実現を可能とする順応的ガバナンスの要件を明らかにする。この目的に従い、第１に関係者の協働と合意形成が可能な到達点、第２に協働と合意形成に基づく絶滅危惧種への負の影響を最小化する「見せて守る」方法の構築、第３にその方法を持続可能なものとする順応的ガバナンスの要件の解明を目指す。
これまでに以下の研究を進めてきた。第1に知床(シマフクロウ)、佐渡(トキ)、豊岡(コウノトリ)、という国内3地域において、関係者への聞き取り調査を実施し、絶滅危惧種の観光利用の目的、利害関心、関係者のネットワーク構造を把握し、保護関係者と地域の関係者の主張の共通点と相違点を明らかにした。
第2に観光利用による影響が懸念されているシマフクロウの生息地域において、ポストコロナ時代を見越したIT技術を活用した「生息地に見に行かない見方」を実験している。具体的手法は巣内画像及び採餌場所の画像に解説記事を加え、インターネット経由での配信である。閲覧者から感想・意見を収集し、画像配信による見せ方の効果を検証している。第3にインターネットおよび札幌市で野鳥観察に関するアンケートを実施した。

Collaboration with citizens is becoming essential for maintaining and managing public green spaces. Citizen groups and participants are aging, and securing human resources has become an issue. This study conducted a questionnaire survey and group interview surveys on collaboration with citizens in natural and urban parks.
We conducted case studies in the management of mountainous areas, grasslands, coastal areas, forests, and urban flower beds and parks. We identified factors that promote or discourage the sustainability of activities, such as the structure of collaboration, the role of intermediate support organizations, and their role in local communities and environmental conservation.

The objective of this study is to evaluate the planning and management of national parks from various perspectives like biodiversity, recreational use, economic effects, regional collaboration, etc., and to propose a framework to utilize its effectiveness in management.
In the management plan, there have been few examples to address regional future visions. From the case study, the place of discussion by stakeholders is important for sustainable tourism development in protected areas. Volunteers on mountain trails are expected to benefit their lives and health. However, general citizens have not recognized the effects of multifaceted values of national parks. The proposed draft of the management effectiveness evaluation indicators can be utilized in securing transparency of future planning, management and accountability of protected area management.

In Japanese natural parks, such as the country's national parks, overuse of the environment has resulted in the depletion of natural resources and the deterioration of the quality of the natural experience. The purpose of this study is 1) to grasp the state of congestion caused by the concentration of visitors, 2) to clarify the relationship between the level of congestion and the negative impact on visitor experience, and 3) to examine the planning and the management of the parks in order to protect their rustic atmosphere. Based on the study results, the risk of accident caused by visitor congestion was evaluated. The methodology of information dissemination to protect the rustic atmosphere and to manage these risks was also examined. In addition, the impact of the Great East Japan Earthquake of 2011 on visitors in national parks was clarified and the role of the parks was examined and discussed.

This study aims to examine more sustainable management of a world natural heritage site and its adjacent areas in Yakushima Island, including resourcization of local history and folklore. It became more popular that urban residents (women people in particular) who might have influenced by information of travel magazines, travel to Yakushima Island seeking for its wilderness and visit mountain areas such as the Johmon-sugi Cedar. Intensive visitation of mountain areas caused a rise in the percentage of people who felt congestion in peak season. In national forests, there found a lot of forestry remains such as forest railways and settlements; moreover, management system to preserve these remains should be constructed. These remains could be used for educational resources in the medium-term or long-term. It is now a good opportunity for local governments to draw up a comprehensive management plan based on public involvement for diverse resourcization of Yakushima Island.

The natural park system in Japan is insufficient for the concept of risk management. This research project aimed to reveal the actual situation and to examine the future possible park management system improvements. Actual accidents and concerns in national parks were reported by park managers. Visitors were asked to answer their attitudes to risk and responsibilities of outdoor activities in Rishirisan, Daisetsuzan, Shiretoko and Oirase. In addition, we investigated the risk management framework of the Department of Conservation, New Zealand, and the evaluation of the protected area effectiveness in Finland. The possibility of applying to Japanese park system was discussed.

愛甲 哲也
支笏洞爺国立公園の支笏定山渓地域を対象にし、現在の自然公園の公園計画の公園界と地種区分界のそれぞれがどのような由来となっているかを地理情報システムにより計測し、その経緯を整理し,分析を行った。昨年度に引き続き,さらに対象箇所を知床国立公園,大雪山国立公園にも拡大し,地図データを入手し,公園計画と国有林の施業計画を重ねあわせ、自然公園の地種区分と、国有林の保安林指定やレクリエーションの森指定の関連を分析した。その結果,相互は依存関係にあり,自然公園の公園計画に生態系やレクリエーション利用に対する明確な配慮がみられないことが明らかとなった。
さらに、国有林の林班を基準に、自然環境資源に関する情報やレクリエーション資源に関する情報を、地理情報システム上で重ね合わせ、統計解析を行い、自然資源保護と利用体験提供の両側面からの林班の価値付けを行った。土壌や植生,地形的特長から,保護の重要性の高い地区から低い地区まで段階的なクラス分けを行い,アクセスや開発の適正,景観的な見通しのよさなどからレクリエーション的にも段階的にクラス分けを行った。それらのクラスを重ねあわせ,保護と利用の相互の関連を分析した。各林班の得点と現状の公園計画の整合性の検討を行った結果,自然公園内の地種区分において必ずしも保護の必要性の高い場所がそのように区分されているわけではないことなどが明らかとなり,景観プランニング手法に基づく今回の手法が今後の公園計画策定の一つとして提案できる。

愛甲 哲也
山岳地における屎尿処理の影響の評価には、利用者の動態の把握が基礎的情報として欠かせない。しかし山岳地の利用者の把握は、気象条件や地理的条件により制約も多く、役所の統計等のみでは不十分な場合が多い。そこで利尻山の登山口に無人の赤外線カウンターを設置し、1シーズンをとおした登山者数の把握および手法上の問題点を探った。また、屎尿の散乱が見られる場所、登山道の崩壊が著しい場所を記録するために、GPSを用いて地図上に記録した。
夏期の2002年6月18日から8月16日までに鴛泊コースを往復する登山者数は約8,500人と推察された。6月下旬から7月上旬の週末に集中した。時間帯では午前5時台、次に午後3時台が多く、午後9時から午前3時までの夜間にも登山者が計測され、山頂より日の出を見るために夜間に入山する登山者が少なくないことが明らかとなった。
GPSによって記録した、植生が踏みつけられ、大便や使用済みの紙が散乱していた場所と、登山道の崩壊が著しい場所を地図上に記録した。用便が確認されたのは、鴛泊登山口から分岐の間で18箇所(避難小屋周辺含む)、沓形登山口から分岐の間で4箇所(避難小屋周辺含む)、および山頂付近であった。登山道上でもっとも幅員が大きかったのは、沓形コースとの分岐点から直上部の8.6mであった。最も深く登山道が洗掘されていたのは、その上部で、V字型にえぐれ、3mの深さがあった。いずれも火山礫が主体となる標高1,450mから上部である。また利尻山頂上直下では登山道脇の崩落が進んでおり、登山道の幅が1mに満たない箇所もみられた。
赤外線カウンター、GPSを用いることによりインパクトの大きい場所の特定や登山者の動態の把握が可能となり、今後の山岳地管理に有用な情報が得られた。その一方で、カウンターの計測ミスなどの問題も明らかとなり、さらに検討が必要と思われた。

愛甲 哲也
山岳地の野営行為が植生の損失と裸地の拡大に及ばす影響を明らかにするために、大雪山国立公園内のヒサゴ沼キャンプ場において、利用状況(テントの設置位置)、植生(被度、出現種)、土壌(硬度、含水比、仮比重、三相分布、孔隙率、有機物含有量)の調査を行った。
同じサイト内でもテントが常に設置される場所と、まれにテントが設置される場所、テントが設置されない場所があり、野営行為によるインパクトの量が異なることが推察された。
テント設置位置から利用量により調査区を3段階(なし、小、大)に分類し、比較を行った結果、インパクトの程度に違いがみられた。植生に関しては利用量の大きい調査区では、被度が小さく、出現種が少ないことが示された。土壌に関しては、利用量の大きい調査区では硬度(支持強度)は大きく、含水比は低く、仮比重(容積比重)が大きくなることが示された。さらに、利用量の小さい調査区においても利用量の大きい調査区と同程度に気相が減少していることが示された。孔隙率も利用量の大小にかかわらず、利用が行われている調査区では低く、僅かな利用でさえも土壌の固結は生じることが示された。
本研究の結果から、野営行為は僅かな利用でさえも土壌や植生に影響を及ぼしていることが明らかになり、柵の設置等により利用を集中させた方が現段階ではインパクトの軽減につながると予想された。今後の定期的に、利用による植生、土壌への影響についてモニタリングを行っていく必要があると考えられる。
