• Investigating Visitors’ Perceptions and Behaviors in a Crowded Situation at a Large-Scale Exhibition

  Hyerin Kim, Claudio Feliciani, Sakurako Tanida, Xiaolu Jia, Tetsuya Aikoh, Yasushi Shoji, Katsuhiro Nishinari

  Journal of Disaster Research 19 (2) 370 - 378 1881-2473 2024/04/01 [Refereed]
   

  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.

  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.

  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.

  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.
• Decline in the alpine landscape aesthetic value in a national park under climate change

  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.

  The initial purpose of our study was to understand preferences of stakeholders on green infrastructure for flood control using a discrete choice experiment. However, the results of our study included unexpected findings. According to the utility theory of economics, an inexpensive green infrastructure scenario should have been chosen under ceteris paribus conditions, but our results differed from this expectation. Inconsistent results like ours are often interpreted as indicating bias and/or questionnaire design issues. However, our results can be interpreted using relational values. We studied green infrastructure in a large-scale flood control basin in Naganuma, a town in the Hokkaido prefecture in Northern Japan. We conducted a discrete choice experiment with town residents as stakeholders of the green infrastructure. Through the examination of choice and membership parameters of our results, we interpreted that individual identity and place attachment, which are types of relational values, are taken into consideration in the choice situation of the discrete choice experiment. We also found that a notion of social responsibility, which is also a relational value, can help us to understand unexpected findings that cannot be interpreted in terms of economic theory alone. Relational values contribute to our interpretation of preferences related to managing ecosystem services with implications for green infrastructure, culturally significant wildlife, wildlife-related recreation and flood control.

  © 2018 Elsevier Ltd Investigating visitors’ crowding norms is necessary to establish the carrying capacity of natural recreation areas. For this purpose, several question formats have been used, but it is known that these have methodological issues. To reduce these methodological issues, we compared several different question formats to investigate respondents’ perceptions of acceptable crowding limits, using montage photographs of different numbers of people at four sites in Shiretoko and Yakushima World Natural Heritage Site in Japan. We applied the double-bounded dichotomous choice model used in the contingent valuation method. Our use of conventional long- and short-format question models shows that acceptability decreases as the number of people increases, in single- and double-bounded models. This confirms the findings of past studies. Despite differences in the crowding norms as measured using different question formats, there was little difference in the number of people depicted in the photographs. The logit model of the double-bounded dichotomous choice model makes it possible to analyze the impact of differences in the number of people and other relevant factors, including the respondents’ characteristics and attitudes. The number of respondents and the burden on respondents vary in each question format, and each provides different information to managers. Management implications: • A double-bounded dichotomous choice model is shown to be a suitable method to analyze crowding norms at natural recreation sites. • This model is less burdensome for respondents and requires fewer samples than some other methods. • The choice model also permits one to analyze the influences of visitors' characteristics and other factors on crowding norms.

  This study aims to understand the preferences regarding 15 services in ecosystem and facilities provided by urban green spaces using a partial profile choice experiment. The method is one type of discrete choice experiment in which researchers present respondents with only a subset of all the attributes under consideration. Therefore, it has the advantage of valuating large numbers of attributes simultaneously. In Northern Japan's Sapporo city area, which is the site of our study, the future vision for urban green spaces needs to be revised, and thus a valuation of the services from ecosystems and facilities provided by urban green spaces is necessary. The survey was conducted in December 2017 by a contracted research company. Respondents were members of the general public that were registered at the research company and live in the study site. The results showed that overall, services from the ecosystem were preferred over those from facilities. "Forming the landscape" and "Providing places to interact with the forest," which are generally considered requirements of urban green spaces, were highly valuated, as were "Conserving biodiversity" and "Providing evacuation sites," neither of which have been previously considered major services in the context of Japan's urban green space management. Finally, despite Japan's declining birth rate and aging population, "Providing facilities for the elderly" was valuated lower than "Providing facilities for children."

  © 2019 John Wiley & Sons Ltd In recent years, we have experienced mega-flood disasters in Japan due to climate change. In the last century, we have been building disaster prevention infrastructure (artificial levees and dams, referred to as “grey infrastructure”) to protect human lives and assets from floods, but these hard protective measures will not function against mega-floods. Moreover, in a drastically depopulating society such as that in Japan, farmland abandonment prevails, and it will be more difficult to maintain grey infrastructure with a limited tax income. In this study, we propose the introduction of green infrastructure (GI) as an adaptation strategy for climate change. If we can use abandoned farmlands as GI, they may function to reduce disaster risks and provide habitats for various organisms that are adapted to wetland environments. First, we present a conceptual framework for disaster prevention using a hybrid of GI and conventional grey infrastructure. In this combination, the fundamental GI, composed of forests and wetlands in the catchment (GI-1) and additional multilevel GIs such as flood control basins that function when floodwater exceeds the planning level (GI-2) are introduced. We evaluated the flood attenuation function (GI-1) of the Kushiro Wetland using a hydrological model and developed a methodology for selecting suitable locations of GI-2, considering flood risk, biodiversity and the distribution of abandoned farmlands, which represent social and economic costs. The results indicated that the Kushiro Wetland acts as a large natural reservoir that attenuates the hydrological peak discharge during floods and suitable locations for introducing GI-2 are concentrated in floodplain areas developing in the downstream reaches of large rivers. Finally, we discussed the network structure of GI-1 as a hub and GI-2 as a dispersal site for conservation of the Red-crowned Crane, one of the symbolic species of Japan.

  Donation is one of the most important solutions to inadequate funding for protected area management however, there has been little agreement on the measures to be used to encourage visitors to donate. We conducted a field experiment in Daisetsuzan National Park, Japan, to examine the effect on donation behavior of providing information about two types of initial contributions. The first type of contribution is toward the fundraising campaign for trail maintenance and the initial amount of government funding (i.e., seed money) and information is provided about the target amount. The second type is for trail maintenance and information is provided on the value of one day's contribution by other participants. We found that announcing the seed money amount and the target significantly increased the probability of a positive contribution and raised the average contribution, compared with the control treatment of no additional announcements. When the participants knew others' contribution beforehand, the likelihood of a positive contribution increased however, the average contribution tended to decrease. In conclusion, announcing the seed money and the fundraising target is superior to the other measures studied in this paper to raise funds in this specific context of protected area management.
• Citizens promote the conservation of flagship species more than ecosystem services in wetland restoration

  Assessing the non-market value of biodiversity conservation is crucial to justify it economically. Using a choice experiment on wetland restoration in Hokkaido, northern Japan, we assessed the willingness of citizens to pay for different ecological statuses of a flagship species (absence, occasional occupancy, permanent occupancy, and breeding) and other principal conservation targets (establishment of a birdwatching station and wetland sizes). The results showed that the fundraising potential of the flagship species surpassed those of other conservation targets, irrespective of its ecological status, highlighting the superior publicity generated by charismatic species. We also showed that upgrading ecological status from occupancy to breeding did not result in additional financial support. Our study emphasizes that, although publicizing ecologically important statuses such as breeding is critical for successful conservation efforts, focusing much effort on flagship species rather than other conservation targets may be important to increase the economic value of conservation practices if such species are available.
• Demand for bear viewing hikes: Implications for balancing visitor satisfaction with safety in protected areas

  Journal of Outdoor Recreation and Tourism 16 44 - 49 2213-0780 2016/12/01 [Refereed][Not invited]
   

  Wildlife viewing is a popular activity in wilderness recreation areas. However, a desire to avoid human–wildlife conflicts often results in trail restrictions though meant to safeguard visitor safety, these restrictions can curtail park visitors’ opportunities to see wildlife against their wishes and limit a park's economic benefits for the local community. Visitor demand for wildlife viewing must be balanced against the need for public safety. Little research has been conducted on the balance between wildlife-viewing opportunities and human safety. This study uses a discrete choice experiment to quantify park visitors’ willingness to pay to view brown bears (Ursus arctos) on hiking trails in Japan's Daisetsuzan National Park. A latent class model is applied to capture preference heterogeneity among park visitors. The results reveal that two visitor groups—non-local and local—are involved. Non-local visitors evince significant demand for bear viewing and bear-related lectures from trained guides. They also prefer group tours and round-trip hikes that include currently restricted areas. On the other hand, local visitors are not interested in either bear viewing or group tours they do not want extra information from the guide but prefer to hike to the closest destination from the trailhead. These results suggest that implementing a variety of zoning management practices and well-designed nature-based tours in bear habitat areas can improve visitor satisfaction and provide new economic benefits while also protecting visitors from bear attacks. Management implications • The present study has shown that the introducing organized bear viewing tours can create a win-win situation for park visitors and a local community. • This study has demonstrated that bear viewing tours do not only satisfy with visitors’ demand for bear viewing but also enhance their safety by promoting group-hiking in a bear habitat. • This study strengthens the idea that bear viewing tours provide new economic benefits to the local community while avoiding unexplained trail restrictions.

  This study explored visitors' preferences for social conditions of trail use in urban forests. It is important to understand the heterogeneous nature of visitor preferences because the recreational use of urban forests is characterized by multipurpose uses with different visiting motivations. To understand preference heterogeneity, this study used a discrete choice experiment using a latent class model that incorporated motivational and sociodemographic factors as membership likelihood function. In 2006, 256 visitors to the Nopporo Forest Park, Hokkaido, in northern japan, completed questionnaires with a series of discrete choice tasks using computer-manipulated images presenting various social conditions of trail use, such as visitor numbers and harvesting behavior on wild food plants. The study identified two visitor groups. One group consisted of more elders whose motivation was to enjoy the natural environment. Although they tended to tolerate crowded conditions, they particularly disliked plant pickers, who harvest wild vegetables alongside the trail. The other group was less tolerant of crowds, and enjoying the natural environment was not their primary purpose for visiting the park. These visitors especially disliked excessive numbers of visitors, but they did not dislike plant pickers. These results suggest that traditional park management assumptions about typical visitors poorly serve the heterogeneous nature of the visitor population. (C) 2016 Elsevier GmbH. All rights reserved.
• How many broadleaved trees are enough in conifer plantations? The economy of land sharing, land sparing and quantitative targets

  Journal of Applied Ecology 53 (4) 1117 - 1126 0021-8901 2016/08 [Refereed][Not invited]
   

  For biodiversity conservation to be an effective and significant social investment, non-marketed values of biodiversity conservation and its associated opportunity costs should be evaluated in monetary terms. In this study, we measured the willingness to pay (WTP) for bird abundance using a choice experiment (CE) based on the random utility model. We performed a cost-benefit analysis to identify the optimal proportion of broadleaved trees in conifer plantations on a volume basis to maximize the social benefits of bird conservation and wood production. The results suggested that respondents to the CE were not satisfied with their current situation and preferred an increase in bird abundance. However, the estimated WTP indicated diminishing returns of bird conservation. More specifically, WTP first greatly increased before gradually experiencing decreasing marginal values, reaching its peak and finally decreasing slightly with increasing bird abundance. Optimization analyses indicated that when the relationship between bird abundance and broadleaved tree proportion was convex, semi-natural plantations with nonzero broadleaved tree proportion (002-022) were always optimal options. When the relationship was linear, optimal broadleaved tree proportion ranged from 0 to 078 and was greatly affected by wood values. When the relationship was concave, there were only two optimal broadleaved tree proportions: a very high proportion (approximately 090) and the lowest possible proportion (0). When the convex and concave relationships approached the linear form, comparable benefits could be attained across broad ranges of broadleaved tree proportion both within and across the relationships. In such cases, it would be useful to increase the likelihood of a feasible land-use strategy of either land sparing or land sharing in order to be successful.Synthesis and applications. It can be difficult to set quantitative targets in biodiversity conservation solely on an ecological basis, and social benefits of biodiversity conservation can create diminishing returns in many situations. The framework we propose shows how to reconcile resource production and biodiversity conservation in the real world.
• Public segmentation based on the risk perception of brown bear attacks and management preferences

  European Journal of Wildlife Research 62 (2) 203 - 210 1612-4642 2016/04 [Refereed][Not invited]
   

  The purpose of this study is to segment residents based on their perception of the risk of brown bear attacks. In addition, in order to design effective risk communication, we investigated the association between residents' risk perception and their sociodemographic characteristics and beliefs. We conducted a questionnaire survey of residents of Shibetsu Town, Japan. For this survey, questions, developed from several risk perception studies, were used to evaluate the perception of the risk of brown bear attacks. Using a principal component analysis (PCA), we obtained four principal factors: seriousness, avoidability, accountability, and management. Furthermore, a cluster analysis using the PCA factor scores identified three groups of respondents with significantly different risk perceptions. Each group had significantly different sociodemographic characteristics and beliefs. Group 1 respondents had had negative experiences with bears, and therefore considered bear attacks to be high risk. In contrast, group 2 respondents felt less accountable for bear attacks because their lives were less connected to the bears. Finally, group 3 respondents had positive attitudes towards bear conservation. They perceived that, owing to increasing bear populations, bear attacks were unavoidable; however, they did not think the risk was serious. Segmentation based on risk perception can help to reduce potential human-wildlife conflicts and improve wildlife management.
• Reducing the extinction of experience: Association between urban form and recreational use of public greenspace

  Halting the 'extinction of experience', the progressive disengagement of people with the natural world, is vital to human health and wellbeing and to public support for global biological conservation. Home to the majority of humanity, urban areas are the key for engaging people with nature, raising the crucial question of how cities should best be designed to facilitate these experiences. For the purposes of maintaining local biodiversity, intensive development within a small area (land sparing) has been shown to be better than extensive development over a large area (land sharing). Here, we investigated for the first time how different city forms affect people's experience of nature, measured in terms of their use of greenspaces. We selected five pairs of land-sharing and land-sparing study regions with different coverage by greenspaces within the city of Tokyo, central Japan and used a questionnaire survey to determine the use residents made of these spaces. We found the frequency of people's recreational use of urban greenspaces was higher in urban land-sharing than land-sparing regions. Moreover, satisfaction with local green environments was also higher in land-sharing regions. This suggests a potential conflict in the design of cities between the urban form that is most desirable for the direct protection of regional biodiversity, and that which best promotes people's nature experiences and the support for its wider protection. A strong emphasis on the advantages of land sparing may increase the separation of humans from nature, and further reduce public interest in, and awareness of, biodiversity and its benefits.

• Heterogeneous preferences for winter nature-based tours in sub-frigid climate zones: a latent class approach

  Yasushi Shoji, Takahiro Tsuge

  Tourism Economics 21 (2) 387 - 407 1354-8166 2015/04 [Refereed][Not invited]
   

  This study investigates off-season tours by examining people's heterogeneous preferences for nature-based tours in sub-frigid climate zones. To explore heterogeneous preferences for winter nature-based tours in Shiretoko, Japan, the authors conducted a discrete choice experiment with a latent class model. Even though the visitors' preferences were different, it was possible to segment them into three groups based on the results. The first segment clearly preferred a wildlife observation tour and considered the possibility of finding rare eagles and detailed interpretation highly important. At the other extreme, the second segment preferred an adventure-based drift ice tour and were not interested in eagles or detailed interpretation. The final segment comprised those visitors whose preferences were between these two extremes. The findings show that, for satisfactory and profitable tours, tourist agents should provide specific recreation experiences to cater to these heterogeneous preferences rather than experiences thought to be acceptable to all visitors.

  Our study reveals trade-offs associated with human- wildlife conflicts in recreation areas. It is common for recreational users to face risks of wildlife attacks while hiking. Although some studies show that recreational users consider trade-offs between three dimensions of recreational experiences consisting of resource, social and management conditions, there are no studies addressing human-wildlife conflicts from the perspective of the trade-offs for the users. To better understand trade-offs considered by recreational users, we performed a discrete choice experiment. We conducted a questionnaire-based survey among recreational users at the Numameguri hiking trail in Daisetsuzan National Park, Japan, which has a high density of brown bears. Using a series of choice tasks, respondents indicated a preferred trail scenario from a group of alternatives. Scenarios varied in terms of their destinations (resource), crowding (social), management system (management) and bear encounter risk (bear appearances on the trail and bear appearances on mountain slopes seen from the trail). Results show that risk conditions have decisive, negative effects on satisfaction level for those hiking. Specifically, when the risk of encountering brown bears on the trail is high, user satisfaction cannot be increased on the other three dimensions. A consideration of only resource-, social-and management-based indicators is insufficient for understanding recreation experiences in areas with a high risk for human-wildlife conflict. At the recreation areas that are home to large wildlife, a guided tour may leave users more satisfied and safe from wildlife attacks. Understanding trade-offs related to the risk helps tour design and enhances the users' experience.

  The purpose of this study is to examine the preferences of Japanese consumers for certified forest products and estimate their price premiums using a discrete choice experiment. Although Japanese consumers have almost no opportunity to purchase forest certification products now, except paper and paper-related products, Japan may be a promising market with significant scope for increasing the demands for the forest certification products. Each choice task of our discrete choice experiment contained alternative wall renovation scenarios with interior wood materials showing five attributes. In 2008, 150 respondents living in Sapporo, northern Japan, completed our questionnaire, which contained a series of the choice tasks. To understand heterogeneous preferences and identify consumer segments in a systematic way, a latent class model was applied. The results show that the mean price premium on Forest Stewardship Council certification of interior materials was 40.5% under a ceteris paribus condition. However, two identified consumer segments both placed greater value on other attributes of the interior materials: dimensional stability and/or area of production. The results indicate that for suppliers of forest products outside of Japan, the merit of forest certification and the demerit of foreign product will cancel each other out in Japan.

  Tourism Management Perspectives 8 (October) 18 - 27 2211-9736 2013/10 [Refereed][Not invited]
   

  Increasingly there is a call for appropriate management policies to be implemented in national parks to minimize the impacts of tourism on both ecosystems and recreational settings. One facet of such problems is that of traffic congestion as car ownership grows. This study applies a traffic Cellular Automaton Model (CAM) as a decision support tool to ease traffic congestion at Shiretoko National Park in Japan. Despite serious traffic congestion having been reported in the park, a new guiding system and the regulation of private car use was started in the same year. This study shows that a probable increase in traffic congestion can be expected after the introduction of these new management systems, but congestion can be relieved by a slight modification of the temporal and spatial daily inflow of visitors. This study highlights the benefits of computational modeling to support decision-making regarding traffic management in protected areas. © 2013 Elsevier Ltd.

  Journal of Forest Economics 林業経済学会 59 (3) 10 - 20 0285-1598 2013 [Refereed][Not invited]
   

  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.

  Visitor information often serves as the basis for the management plan of parks. However, there exist few scientific and fundamental surveys for parks and open spaces in Japan. We analyzed the correlation between the number of visitors and the various factors in a suburban open space in a northern Japanese city, Takino Park. To explain the fluctuations in the number of visitors in Takino Park, multiple regression analyses with the stepwise method were conducted. The analyses employed social factors and meteorological factors, such as the day of the week, school vacations, temperature and the weather. The results show that the most influential factor is the day of the week, i.e., Sundays and holidays. The weather is also influential as the number of visitors decreases on rainy and snowy days. Comparing different seasons of the year, we found that influential factors varied from one season to the other. A key distinguishing finding of our results is that the weather conditions at the departure site and the weather forecast are also determining factors. These findings will help park managers understand the current situations and examine future management strategies to maintain and enhance visitor satisfaction, and improve information services.

  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.

  Increasing pressure to diversify development of national parks emphasizes the need for new and relevant information for park management decisions. In this paper, we use choice experiment to value different tradeoffs that evolved in park development scenarios. Specifically, we examine which kind of development profiles are worth considering and which paths not to follow. We focus on biodiversity and recreational services provided by Oulanka National Park in Finland, which represents a popular recreation site attracting a large number of visitors. The increase of biodiversity was the most highly valued feature by the respondent national park visitors. Thus, our results show that the protection of biodiversity and recreational and tourism use of national parks can cause conflicting welfare effects if managed in inappropriate ways. Increasing the number of visitors, expanding present resting places, constructing new resting places and an intense increase in information boards, especially if combined with shrinking biodiversity, are welfare reducing managerial actions in national parks.

  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.

  Journal of Forest Economics 林業経済学会 57 (3) 22 - 30 0285-1598 2011 [Refereed][Not invited]
   

  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.

  Differences in trail preferences for social conditions of visitors to forests in Vienna and Sapporo were investigated in 2006 using a standardised image-based stated choice approach. On-site visitors to two comparable pen-urban forests - the Lobau Forest in Vienna, Austria (n = 373), and the Nopporo Forest in Sapporo, Japan (n = 256) - evaluated the same sets of computer manipulated images depicting 128 trail scenarios with different levels of social stimulation. Latent class segmentations, in three sub-segments of similar sizes, differentiated by partly opposite preferences for social conditions, were derived for both samples. A positive contribution of social stimulation to preferences was found for about 17% of Nopporo and 9% of Lobau respondents, while for close to 50% of Lobau respondents and 38% of Nopporo respondents very low levels of social stimulation were preferred. The results indicate that urban forests should be managed for users with a desire for low social densities as well as a denser social setting providing some levels of social stimulation.

  We conduct an experimental survey to analyze how rules for collective decision-making influence individual preferences regarding nature restoration plans. Our study compares two decision-making rules-a consensus rule and a majority rule-wherein participants decide on a plan regarding nature restoration in the Kushiro Wetland, Japan. Our main finding is that the difference between the individual preferences and collective decision-making is less significant under the consensus rule than the majority rule. Furthermore, there is a larger disparity with regard to the marginal willingness to pay between collective and individual decisions when participants are unsatisfied with the results of collective choice.

  Landscape and Ecological Engineering 4 (2) 103 - 113 1860-1871 2008/11 [Refereed][Not invited]
   

  As the pace of ecosystem restoration increases, more attention has been directed towards understanding public preferences for ecosystem restoration projects. This paper utilizes a choice experiments technique to evaluate the restoration project of an endangered species, Nymphoides peltata (known locally as asaza) in Lake Kasumigaura, Japan. The restoration project evaluated in this paper consists of two attributes: an extinction risk and a lakeshore ecosystem. First, we observe a positive willingness-to-pay for the vegetation restoration project: the mean willingness-to-pay for restoring the endangered specie and avoiding extinction was about JPY6,800 and the mean willingness-to-pay for restoring the covering area to the ideal condition that the species originally inhabited in 1996 was about JPY1,600. Second, we clarify what kinds of individual characteristics affect preferences for restoration projects compared with preferences for the status quo. The results show that respondents who have strong environmental attitudes, visit experience, high income, and are female are more likely to prefer restoration projects to the status quo. Third, we investigate whether knowledge and comprehension of ecological information have any influence on respondents' value formations. We find that respondents' comprehension of ecological information is positively related to their willingness-to-pay for the avoidable level of extinction risk attribute, while respondents' knowledge of ecological terms has no effect. Overall, our findings suggest that the public strongly desires the avoidance of extinction of endangered species, and indicates that researchers should be careful about how ecological information is given.
• Estimating annual visitors flow in Daisetsuzan National Park, Japan: combining self-registration books and infrared trail traffic counters

  Journal of Forest Research 13 (5) 286 - 295 1341-6979 2008/10 [Refereed][Not invited]
   

  Information on visitor flow is fundamental to the management of recreation areas. Without such data, recreation managers cannot develop appropriate action plans to maintain a healthy ecosystem and the quality of visitor experiences. Little attention has been paid in Japan on estimating the exact number of visitors to a facility, especially in multi-trailhead systems. A new study in Daisetsuzan National Park, northern Japan, develops a systematic method of estimating visitor flow in complicated trail systems using infrared trail traffic counters and self-registration books. The focus is on using self-registration data that has been underutilized in USA and European countries. Results show that the estimated number of trekkers, 124,000, is almost twice that estimated using only self-registration data, which is commonly adopted by recreation managers as an official number of trekkers. In addition, this method enables us to detect considerable time-series variations of trekker number on any specific trailhead and assists planning measures to combat overuse of segments of the trail system. However, characteristic of this method is that the estimators are biased, and always underestimates. And the smaller the number of visitors at a low-used trailhead, the larger the error is likely to be. Furthermore, an extremely high rate of one-way-trip trekkers on self-registration data invites a critical error. We must also draw attention to the flaws, when we implement this method.

  Understanding a site-choice behavior of park visitor has been a major focus of research in management of national parks and protected areas. 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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

• Evaluating ecosystem services from retention forestry in planted forests from a large-scale experiment

  Japan Society for the Promotion of Science：Grants-in-Aid for Scientific Research

  Date (from‐to) : 2013 -2017 

  Author : OZAKI KENICHI, SAYAMA Katsuhiko, NAKAMURA Futoshi, YAMANAKA Satoshi, INARI Naoki, HIRONAKA Yutaka

   

  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.
• Evaluation of management effectiveness of biodiversity, recreation, economy and collaboration in national parks

  Japan Society for the Promotion of Science：Grants-in-Aid for Scientific Research

  Date (from‐to) : 2014 -2016 

  Author : 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.

• An action research on sustainable resourcization of world natural heritage

  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.
• Constructing travel demand model with budget and time constraints

  Japan Society for the Promotion of Science：Grants-in-Aid for Scientific Research

  Date (from‐to) : 2013 -2014 

  Author : 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 purpose of this research is to provide an economic analysis of the environmental policy for the Shiretoko world heritage site from the point of view of the balance between the nature conservation and recreation use. Namely, we considered the recreation management zone system implemented at the Shiretoko five lakes area since 2011, and compared the recreation use before and after the implementation. A field experimental analysis(i. e. natural experiment) for the management system was applied.

  We developed methodology of ecosystem evaluations regarding forests, rivers and agricultural lands. Also, we examined connectivity and historical changes of habitat mosaics and roles of biological legacies such as large wood in recovering processes of vegetation and stream biota. Fishes, invertebrates, plants, amphibians, mussels and mammals were selected as indicator species to evaluate restoration project based upon the results of monitoring and experiment. As for the economical and social aspects, restoration projects were analyzed, and social acceptance and future dimension were discussed.

  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.
