English, Scientific journal, ABSTRACT

Many long‐distance migratory birds are experiencing global declines, creating an urgent need for conservation actions. Engaging public commitment to their conservation is therefore crucial. However, this task is challenging as the social interest diminishes as the geographic distance to conservation issues increases. One potential solution is to reduce people's psychological distance by providing visual information that illustrates how avian migratory routes connect countries and how conservation organizations implement conservation measures in distant countries. In this study, we conducted a discrete choice experiment with the Japanese public (n = 1081) to estimate their willingness to pay (WTP) for conservation measures aimed at improving and protecting the wintering habitats of migratory birds in Southeast Asia (i.e., establishing wetland/forest nature reserves and implementing environmentally friendly farming/forestry). We tested the impact on WTP of showing respondents avian migratory routes and photographs of activities undertaken by conservation organizations in Southeast Asia. Contrary to predictions, showing the evidence‐based migratory routes connecting Japan and Southeast Asia had limited effects on the WTP of the Japanese public for conservation measures in Southeast Asia. Surprisingly, showing photographs of activities undertaken by conservation organizations in Southeast Asia had slightly negative impacts on WTP. Instead, WTP was strongly linked to subjective connection with nature (nature relatedness), with those exhibiting a stronger nature relatedness showing higher WTP. People showed higher WTP to establish nature reserves in Southeast Asia than to implement environmentally friendly farming/forestry in Southeast Asia, and there were weak negative interactions between implementing nature‐reserve establishment and environmentally friendly farming/forestry simultaneously. These findings suggest that providing visual information alone may not be effective to foster social support for conservation measures in distant countries. Rather, approaches that cultivate the connection with nature—such as environmental education, residential camps, and local nature experiences—are needed, ideally beginning from a young age.

English, Scientific journal, Farmland abandonment contributes to agroecosystem degradation and food crises. Sustainable farmland use requires a well-designed agri-environmental policy to provide farmers with incentives, including agroecosystem services apart from food production. One of these is recreation. Here, we focus on a Japanese terraced paddy land. We assessed seasonal changes in the value of recreational ecosystem services by integrating mobile phone big data of on-site visitors, collected between 2018 and 2020, into a valuation method. The application of mobile data enables the precise and consistent analysis of non-market agroecosystem services. The recreational value of the paddy land varied with season but overall was high. Sustainable farmland use provides social benefits, and we support the validity of agri-environmental policies that relate to economic incentives for agroecosystem conservation. However, the results show that the incentives provided by the public/government may be insufficient in comparison to this recreational value. Our findings provide information regarding the appropriate amount of economic support required to achieve sustainable agricultural land use in this setting.

English, Scientific journal, Understanding how visitors respond to crowding is crucial for ensuring the success, safety, and overall enjoyment of large-scale exhibitions. However, despite its significance, limited research has explored this issue. To address this gap, we conducted a questionnaire survey in 2022 and 2023 for visitors to exhibitions held at the Tokyo Big Sight Convention Center. Our research aims to explore the level of consistency between perceived and actual crowding, levels of discomfort in crowded situations, tolerance levels for crowding, and behaviors to avoid crowded situations. The results revealed significant changes in visitor perceptions across the two-year period. Notably, the acceptable crowd density in 2023 increased by 13% compared to 2022. This change in level of tolerance for crowding might have been influenced by the COVID-19 pandemic and other contextual factors that altered visitors’ perceptions toward crowding. Interestingly, despite these perceptual changes, behaviors to avoid crowded situations remained consistent across both years. The most common response was that no special action was taken to avoid crowded situations. These findings underscore that perceptions and behaviors related to crowding in the context of large-scale exhibitions are not uniform. Our findings offer several implications and insights for crowd management, which event organizers can use to devise strategies aimed at enhancing visitors’ experiences and effectively managing crowding in large-scale exhibitions.

English, Scientific journal, In some natural parks, introducing a shuttle bus system as an alternative to private cars can help reduce congestion and protect nature. This study examines the pilot program to effectively induce visitors to switch to the shuttle bus, while examining the visitors’ understanding of the expansion of the restricted vehicle section in Shiretoko National Park—a World Natural Heritage site known for its rich natural resources, especially as a high-density habitat for brown bears. There are concerns about conflicts between visitors and brown bears that appear along roads. Visitor restrictions, such as limited access to transportation, limit the use of a place and alter the behavior and experience. Therefore, careful consideration is needed before introducing visitor restrictions. The results of our questionnaire survey of visitors indicated that most favored the expansion of the shuttle bus section. The choice experiment revealed that the guides on the bus and an optional experience encouraged visitors to switch to the shuttle buses. Nonetheless, awareness of the pilot program was low, and some visitors preferred their cars, indicating the need for further promotion of awareness and understanding of these new measures.

English, Scientific journal, Regulated egress is often conducted after large events to avoid extreme congestion at stations around event venues. In regulated egress, people are divided into several groups and egress in order. By controlling the number of groups and the time interval between each group’s egress, managers can mitigate the congestion at the stations. In this study, a mathematical model was developed to identify the effective regulated egress. level of discomfort (LOD) was used to evaluate the performance of the regulated egress instead of the total egress time. LOD is the product of the function of density and duration of egress and represents the accumulated discomfort through the egress. A questionnaire survey was conducted to determine the LOD function parameters. Under the assumed conditions, the results of the calibrated model indicated that effective regulated egress could be conducted by dividing the people into two or three groups, which is presumable in terms of management in the real world. In addition to the main result for the effective number of groups, the robustness of the model was confirmed by comparing the results of the two types of LOD functions. In other words, the effective number of groups does not strongly depend on the detailed form of the LOD functions.

English, Scientific journal, Summary

Message framing contributes to an increase in public support for invasive species management. However, little is known about people’s preferences for the multiple objectives of management within different contexts relating to the challenges and benefits of invasive species management. We examine Japanese citizens’ preferences for the goals of free-roaming unowned cat (Felis catus) management in three contextual frames by applying experimentally controlled information and the best–worst scaling technique. Our results indicate that the ecological frame highlighting the ecological impacts of free-roaming unowned cats on native ecosystems significantly increases Japanese citizens’ concern about cat predation, although the frame did not change the preference ranking of goals. There are differences in the effects of message framing depending on cat ownership. The best–worst scaling technique shows that Japanese citizens prefer to maintain a sanitary environment, followed by the prevention of zoonotic diseases. Although the ranking of sanitary environmental management does not depend on cat ownership, the ranking of the other goals differs depending on cat ownership. The findings highlight the importance of strategic message framing and its prioritization in encouraging public support for invasive species management.

English, Scientific journal, Alpine landscapes are projected to be degraded under climate change, which would threaten their benefits to society. Previous studies, however, have been limited to aesthetic change, and it remains unclear how much the aesthetic change would affect human welfare. To address this issue and gain insights into climate change adaptation policies, we conducted a choice experiment survey using digitally manipulated images based on climate change scenarios and natural scientific knowledge in a mountainous national park in Japan. We uncovered that park visitors appreciate the alpine landscapes that include snow patches on mountains and some types of alpine flowers by analyzing the data from 445 respondents. Conversely, both the invasion of alpine vegetation by dwarf bamboo and the disappearance of snow patches due to climate change substantially deteriorated the perceived aesthetic benefits from alpine landscapes. The economic loss caused by climate-induced landscape degradation was estimated at more than 100 USD per visitor, at maximum; the disappearance of snow patches and invasion by dwarf bamboo reduced the benefits by approximately 13 USD and 101 USD, respectively. Our findings suggest that sustaining the aesthetic value of alpine landscapes in national parks via climate change adaptation has potentially significant economic benefits. By supposing that the mountain national park attracts 70,000 visitors in summer, climate change would cause as a minimum of eight million USD economic loss at the park without appropriate measures annually. Our findings highlight the importance of climate change measures by considering climate change impacts on social benefits associated with alpine landscapes.

Japanese, 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.

Wildlife Conservation Japan, 13, 2, 9, 8, Association of Wildlife and Human Society, 2012, [Peer-reviewed]
Japanese, This study explores the potential demand for a bear-watching tour under consideration in Daisetsuzan National Park, Hokkaido, northern Japan, using choice experiment. The brown bear (Ursus arctos yesoensis) is representative of land mammals in Hokkaido. Local residents have overlooked to recognize bears as a potential tourist attraction; however, a bear-watching tour could provide benefit for local residents. Previous studies have shown that this kind of tour also improved wildlife management. A questionnaire survey was conducted in September 2008, and 302 responses (50.3%) were returned by mail. After removing respondents who were not interested in the tour, we analyzed the remaining 190 completed responses. Conditional logit model estimates demonstrate that the willingness-to-pay for the ideal tour, which is the best combination of tour destinations, group sizes, information services and probability of finding bears, is 8,804 JPY; thus, the tour would be profitable for the local residents. However, mixed logit model estimates show that hikers have heterogeneous preferences for tour destinations and information services. Therefore, varieties in terms of tour destination and information services are required to meet hikers' demands.

Japanese, The eco-tour has been encouraged in Shiretoko, a world heritage site, northern Japan, to balance nature conservation with local economy. To keep the number of participants of the tours, acquiring both of new visitors and repeaters is needed. The purpose of this study is to examine what kind of eco-tour should be provided to acquire the new visitors and the repeaters. To understand the preferences of them, choice experiments were applied to general public which contains potential new visitors and on-site visitors which contains potential repeaters. The result shows that the potential new visitors prefer the famous destinations such as Kamuiwakka, while the potential repeaters prefer the sites where they can enjoy primitive settings such as Lake Rausu. Furthermore, there are differences between the preferences for the quality of lecture provided by tour guides and the number of the participants of a tour. The potential repeaters only prefer detailed explanation of the guides and the tour with the small number of participants.

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.

This paper addresses a site-choice behavior of general public using choice experiment for six national parks in Hokkaido, Japan : Rishiri-Rebun-Sarobetsu, Shiretoko, Daisetsuzan, Akan, Kusiro-Shitsugen, and Shikotsu-Toya National Park. The result shows that visiting each national park is valued by respondents. The highest willingness to pay is JPY 80,767 for visiting Shiretoko National Park, and the lowest is JPY 16,476 for Shikotsu-Toya National Park, for example. In addition, a short travel time is positively valued as expected. A willingness to pay for additional one hour is JPY-2,289. On the basis of the results and rates of past visitation for these national parks, recreation opportunities expected by visitors are all different respectively, therefore; role-sharing and characteristic park plans to meet various taste of recreation or tourism in Hokkaido need to be prepared.

Journal of The Japanese Institute of Landscape Architecture, 71, 5, 727, 730, Japanese Institute of Landscape Architecture, 2008, [Peer-reviewed], [Corresponding author], [Domestic magazines]
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.

An Economic Assessment of impacts on visitors by cooperative funding : A case study applying CVM in Yakushima Island, Kagoshima, JAPAN

ENVIRONMENTAL SCIENCE, 21, 4, 307, 316, SOCIETY OF ENVIRONMENTAL SCIENCE, JAPAN, 2008, [Peer-reviewed], [Last author], [Domestic magazines]
Japanese, Movement in search of benefit-received principle spreads in natural parks in Japan as a background of financial difficulties. Although the principle is reasonable, impacts on visitors have never been studied so far, when price settings become higher than before or the number of recreation sites that introduce cost burden increase. This paper discusses issues on a cooperative funding, which is a widely-distributed practical method of benefit received principle in Japan. On-site sampling contingent valuation survey was conducted in Shiratani Unsuikyo and Yakusugi Land, Yakushima Island. The results indicate that an increase in setting of price from JPY 300 to 500 decrease 5% of the number of current visitors. And an increase in pricing to JPY 1, 000 decrease 20% of them. Furthermore higher pricing have more serious impact on younger visitors and visitors living in the vicinity of the island. Moreover, in the present circumstances, almost all of associations that operate the cooperative funding have independent accounting system and no partnership with other associations, therefore; prevalence of the current system without coordination has a possibility to impede the solution of the problems.

A Study on Evaluations of Trail Maintenance by Hikers and Stakeholders
AIKOHA Tetsuya, KOBAYASHI Kihiro, SHOJI Yasushi, YAMAKI Kazushige
Journal of The Japanese Institute of Landscape Architecture, 69, 5, 645, 650, The Japanese Institute of Landscape Architecture, 27 Mar. 2006, [Peer-reviewed], [Domestic magazines]
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.

Japanese, Providing measures to relieve over-use problems are important for management of alpine recreation areas in Japan. For discussing how to control number of visitors, or how many visitors should be limited, it is essential to understand site-choice behavior in those areas. In this study, we explored the modeling of site-choice behavior applying choice experiment, using a sample of fall trekking season in Daisetsuzan National Park. Our results showed that condition of fall leaves and crowding have significant effects on site-choice behavior as well as recreational settings of destination, itinerary, and trekking times. These results will be particularly applicable in designing "regulated utilization area" system that the Ministry of the Environment established in 2003 for coping with over-use situation in National Parks and Quasi National Parks in Japan.

JOURNAL OF THE JAPANESE FORESTRY SOCIETY, 85, 1, 55, 62, THE JAPANESE FORESTRY SOCIETY, 2003, [Peer-reviewed], [Domestic magazines]
To conserve naturalness and establish systematic recreational use management in alpine natural parks, it is essential to clarify each zone's recreational characteristic and management goal in the area, and develop recreation facilities and manage the area in keeping with the goal. This study classified recreation areas in Daisetsuzan National Park using ROS (Recreation Opportunity Spectrum), a planning concept that takes into account the recreation experiences of users. Data concerning users were obtained from a questionnaire survey, and then users were classified into four groups that prefer different levels of facility development, accessibility, etc. Using these results, we classified the areas into four types from a zone with more human influences, development and visitors to a zone with less human influences, development and visitors according to the recreation settings of the zones. We concluded that we could make an objective and rational park plan by considering the degree of development and the management principle of each zone from the viewpoint of visitors' recreation experiences.

Comparison of the Value of Outdoor Recreation: A Case Study Applying Travel Cost Method and Contingent Valuation Method(PAPERS OF THE 19th SCIENTIFIC RESEARCH MEETING)

Landscape Research Japan Online, 64, 5, 685, 690, The Japanese Institute of Landscape Architecture, 2001, [Peer-reviewed], [Lead author, Corresponding author], [Domestic magazines]
Japanese, In recent years environmental valuation method has been used as a method of managing Natural Parks in Japan. There are some methods, such as Travel Cost Method (TCM) and Contingent Valuation Method (CVM), that can evaluate the outdoor recreational value and the environmental values. To obtain the reliable valuation, it is important to compare the valuation of TCM with that of CVM. In this study I evaluated the value of outdoor recreation on Uryunuma Mire, Hokkaido, Japan by applying Zone Travel Cost Method (ZTCM), Individual Travel Cost Method (ITCM), and CVM. Then I compared and discussed these results. The estimate mean of ZTCM was 1214.9yen per visit, and that of ITCM was 1552.6yen per visit. The estimate median and mean of the Single-Bound Model CVM were 1255.7yen and 2260.7yen, and those of the Double-Bound Model CVM were 1192.8yen and 1687.7yen, respectively. Although these values cannot be compared among others directly, all these values relatively concentrated between 1, 000 yen and 2, 000 yen.

The over-use control effect of user fees in the natural park : A contingent valuation study
Shoji Y., Kuriyama K.
Journal of the Japanese Forestry Society, 81, 1, 51, 56, Japanese Forestry Society, 1999, [Peer-reviewed], [Lead author], [Domestic magazines]
Japanese, A problem of the over-use in the natural park causes not only uncomfortable use but also has bad influence for the landscape and ecosystem. We discuss a user fee's effect, especially the effect to the over-use controls. Willingness to Pay (WTP) for a recreational use is estimated by contingent valuation survey for our case study area, Uryunuma mire. Split sample comparison between two elicitation method, payment card and dichotomous choice, is analyzed. The estimated WTPs by payment card are 500 yen for median and 453 yen for mean. The estimated WTPs by dichotomous choice are 2,186 yen for median and 3,322 yen for mean. Our results shows that user fees can reduce the over-use, and visitors who came from far away, had a knowledge about flowers, and had known the that fee have a large WTP.

We evaluated the effects of retention harvesting on ecosystem survices such as water and soil conservation, insect damage control and edible wild plants provision in a large-scale retention foresty experiment in fir plantations in Japan. For water and soil conservation services, water discharge and nitrogen runoff one year after harvest were affected by retention levels of broad-leaved tress in each experimental plot. For services to protect insect damage, avian predation on artificial caterpillars did not correlate with small bird density. Also, growth rate of todo-fir aphids (Cinara todocola) on fir seedlings differed with ant species that attended colonies of todo-fir aphids. For the provision of edible wild plants, we determined the change in the abundance of these plants after harvest and estimated the economic value of these wild plants.

Aikoh Tetsuya
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.

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.

SHOJI Yasushi
The purpose of this research project is to construct travel demand model with budget and time constraints. The project also tried to incorporate multi-purpose and multi-destination trips into the model. My preliminary results represented a way of modeling change in traveler behaviors in national parks by designation of new protected areas and/or policy change. The model is expected to be not only a tool for reducing congestion and environment impact in protected areas, but also a tool for wide range of application in policy planning.

Forest owner's economic incentives for biodiversity conservation are analyzed using environmental economics and forest ecology. First, the survey for forest owners was conducted to develop behavioral model of forest management. Second, spatial data of forests was analyzed using forest GIS. Third, the effects of forest age on the population of birds were statistically analyzed. Fourth, choice experiment study was conducted to estimate the economic value of the ecosystem services of forests. Fifth, economic effects of forest policy to increase bird population were analyzed. Finally, the cost-benefit analysis was conducted to analyze the optimal forest management which maximized the total values of conservation and timber.

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.

The Fundamental Research on Management of World Natural Heritages
Grants-in-Aid for Scientific Research(基盤研究(B))
2005 - 2007
Shin NAGATA, 土屋 俊幸, 柴崎 茂光, 庄子 康
This Project aims to clarify management system as well as current state of recreational use of world natural heritages : Yakushima Island, Shirakami-Sanchi, and Shiretoko in Japan. Ogasawara which is a candidate site for world natural heritage was chosen as our research site, too. Furthermore, management system of Tongariro National Park in New Zealand, which was designated both as world natural and as cultural heritage site, was investigated to compare with Japanese heritage sites.
Concerning Yakushima Island, the cost of maintenance of the entire island dramatically rose after the designation, and management system in Yakushima became very complicated. Over 60% of the local people realized that Yakushima's environment was deteriorating, and they lodged complaints against the public authorities' efforts, saying that they were disrespectful of the opinions of the local residents.
A questionnaire survey for tourists conducted at Shirakami-Sanchi showed that ecotourism conducted in Anmon Area are inclined to mass-tourism because of economic efficiency for ecotourism guides. It was also estimated that tourists' expenditures who visited Juniko-Lake should be around 600 million yen per year and recreational value of the site be 860 million yen per year.
A Conjoint Analysis was applied to ecotourists in Shiretoko Peninsula, and their WTP for an ecotour within guidelines was estimated to be around 10 thousand yen per capita.
In Ogasawara, it was observed that at least 18 local rules for nature resources were build up by local people after 1989, and these rules played an important role in filling gaps between actual situations and legal ones.
Interview surveys for key informants who belonged to Ngati Tuwharetoa or Ngati Rangi around Tongariro National Park, New Zealand so that what to extent public involvement for Maori people was approved. Though Maori people had a chance to give submissions for a draft of Tongariro National Park Management Plan to the department of conservation, there was no reply from the department of conservation.
