    This study focuses on the social value of local public transportation, defined as its spillover effects across various sectors. We attempt to build a model for logically and quantitatively understanding the social value. Specifically, based on findings from previous studies, the effects of local public transportation on sectors such as healthcare and welfare, community development, commerce and tourism, industry and the regional economy, childcare and education, and traffic safety, environment, and infrastructure management were organized into a logic model. Furthermore, issues related to implementing public transportation policies that consider social value were identified through interviews with local governments, and actions to address these challenges were proposed.

    Recently, the preservation and utilization of cultural properties have been actively discussed, and unique venues (UV) are attracting attention as a new way to utilize cultural properties. In this report, we take up the “UV HIMEJI Plan” as a case study to investigate the concept of the “UV HIMEJI Plan” and its current achievements and issues. As a result, it was found that the current plan is a system that allows the use of the site without damaging the value of the World Cultural Heritage site. However, the number of users is low, and there is a risk that an increase in the number of users will cause a loss of the dignity of the World Cultural Heritage and the special feeling required for UV. So, it is necessary to consider what kind of content to select in the future.

    Public bicycle sharing schemes are installed in cities around the world. While the flexibility of the system allowing for one-way and short-distance uses opens the door for combined uses with other modes of public transport, research on such uses are limited. Using data from the Open Data Challenge for Public Transportation, we have created a web-based application “Cycle Shortcut: Beat the Winding Rails” which explored the potential of such rail-shared cycle combined trips in the Greater Tokyo area through rail-cycle combined route-finding, isochrone visualizations, and mapping areas with high cycling potential using network analytical methodologies. The application revealed patterns for stations and areas where cycling can be actively integrated, aiming to reconstruct the transport network-based spatial recognition of the city and potentially transform people’s transportation and cycling behavior.

    The importance of self-help and mutual aid is growing due to the increasing severity and frequency of large-scale disasters. District disaster prevention plans are a resident-centered institutional mechanism for the purpose of improving local disaster preparedness. The purpose of this paper is to investigate the current status of disaster reduction planning in Kobe City 30 years after the Great Hanshin-Awaji Earthquake through interviews and a literature review. As a result, it became clear that there are disparities in the current status of disaster reduction planning in Kobe City among regions, depending on whether they have experienced the disaster or not, and on the structure of their residents. Based on these results, it is necessary to create a new mechanism for community-driven disaster reduction and to promote cooperation with other entities, in accordance with the actual conditions of each community.

    The scope for discretionary judgment by local governments is expanding in urban planning administration, and there is a growing need for unique initiatives and judgment criteria. This paper focuses on the location designation and planning standards for high-rise buildings in Ibaraki City, Osaka Prefecture. Through a comprehensive literature review and interviews conducted in February 2025, the following three points were identified: 1) Ibaraki City's approach is unique and comparable to cases in Germany. 2) Despite the advanced nature of the system, its implementation is minimal. 3) A comparative study with municipalities having similar location characteristics is necessary.

    In recent years, the global push for decarbonization has accelerated the adoption of renewable energy. However, this development has also led to challenges such as environmental degradation and opposition from local residents. In Japan, a country with abundant geothermal resources, geothermal power is being developed as a renewable energy source. Yet, some local governments have implemented ordinances and regulations that place restrictions on such development. Geothermal energy is distinct from other renewables in that it involves specific stakeholders—such as hot spring operators—who are closely tied to local resources, making consensus-building with communities essential. In this context, local regulations play a critical role in geothermal development. This paper focuses on appropriate geothermal energy development in Japan and, through a case study in Beppu-city Kyushu, examines the types of local policies and regulations needed to promote its harmonious integration with local communities.

    The purpose of this study was to focus on changes and factors in the travel patterns of young people around railroad stations before and after the COVID-19. Using the change in the number of passengers as the explained variable, a regression analysis was conducted for 20 stations from Omiya to Akabane Stations. The results indicated that among the younger age groups, differences from other age groups were found in the distance to the central business district (CBD) and the density of surrounding amenities, and that the change in the number of passengers was higher at stations with more extensive amenities near the station. Furthermore, the sign of the estimated coefficient values for the distance to the CBD were reversed depending on whether or not the commuter pass ownership rate was controlled. This suggests that commuting behavior is changing as a result of the spread of telework and online classes due to the COVID-19.

    With the decline in population and the aging of the population, the “Regional Experience Seekers” has been attracting attention, but most of them remain involved only in the area around their place of residence. Therefore, it can be said that although the Regional Experience Seekers can be obtained in areas surrounding metropolitan areas where there are many residents, they are in short supply in areas far from metropolitan areas that need bearers. Therefore, in this study, from the perspective of expanding their involvement to distant areas, we ascertained the current situation and conducted an analysis to expand their involvement. As a result, we found that the higher their income, the more they visit distant areas. Our analysis also suggested that while many of them chose “work-related” as the reason for visiting distant areas, altruistic reasons such as “my companion and the people I am staying with are happy” were influential in their continued involvement.

    The purpose of this paper is to clarify the usage of former military land and buildings by national universities in Northern Kanto region.In Ibaraki Prefecture, the former Tsukuba Naval Air Base was temporarily used by Mito High School which was affected by the air raid. And then, it moved to the former 2nd Infantry Regiment in Mito and, it became the main campus of the Ibaraki University together with the adjacent former Mito Army Hospital. In addition, the Ibaraki Youth Normal School, which was not affected by the air raid, used the former Tsukuba Naval Air Base and opened a farm at the former Nishi-Tsukuba Army Airfield. The Kasumigaura Agricultural College was established at the former Kasumigaura Naval Air Base, which later became the Faculty of Agriculture at Ibaraki University. In Tochigi Prefecture, part of the former Utsunomiya Army Airfield was used as a farm for the Utsunomiya Agricultural and Forestry College, and Utsunomiya University took over the farm. In Gunma Prefecture, the former 15th Infantry Regiment was used by the Gunma Normal School for Boys, which lost its building in a fire, and the Gunma Youth Normal School, which needed to relocate after the WWII. However, Gunma University did not take over it.

    In southern Shiga Prefecture, Omihachiman, Yasu, and Moriyama have populations between 50,000 and 100,000, while Kusatsu has about 140,000, and all have maintained their populations. This study examines changes from 2000 to 2020 in the location of facilities by industry (commercial, medical/welfare, public) and form (stand-alone or complex) within a 1 km radius of major JR stations in these cities. It also compares differences in facility distribution inside and outside this radius, considering urban structure and planning. Key findings include: (1) a decrease in retail facilities, while medical and welfare facilities remained stable or increased; (2) a significant rise in both the number and proportion of complex facilities; and (3) distinct patterns in facility distribution near stations, reflecting each city's unique urban planning and arterial road networks.

    This research focuses on the concept of “Perception Change” and aims to clarify the structure and changes in perceptions of disaster preparedness among (1)consumers (2)companies and corporations, and (3)retailers, and to examine future issues. In this research, the perception of disaster preparedness among consumers is greatly influenced by companies, corporations, and retailers. By creating new products, services and thoughts should not be limited to “stockpiled goods and disaster prevention goods = using in emergency situations”. Those initiatives could change consumers’ perceptions. On the other hand, the fact that so many people are NOT prepared is a problem, because they still draw a line between disaster and extraordinary. While companies, corporations, and retailers are taking a different approach to disaster preparedness, the challenge is for consumers themselves to change their own perceptions of disaster preparedness.

    The purpose of this study is to develop disaster preparedness educational materials for people with intellectual disabilities and to clarify their usefulness and challenges. We also conduct an analysis based on their level of understanding and behavioral characteristics. We found that we need to communicate with them sufficiently while they are learning. We thought that if we spend time talking with them, their learning effect will improve. We also found that they have the potential to deepen their understanding by learning repeatedly. Their level of understanding increased as the level of their disabilities became milder. They also showed behavioral characteristics that hindered their concentration while learning, so it is necessary to create a learning environment.

    This study aims to clarify identify the differences in public GIS in Niigata City(e-map) and New York City(ZoLa).E-map is possible to grasp the details of regulations for the concerned location as urban planning information all at once. On the other hand, ZoLa is possible to select and view layers for each zoning, which is more detailed than in Japan. In addition, detailed information on buildings in individual tax lots is available to the public. Although there are differences in the content and methods of public disclosure through open GIS in the two cities, it is thought that each city can respond to demand in terms of whether or not a building site has been determined when users are considering building or resettling in the city.

    The purpose of this study is to identify the requirements for an effective tool for promoting planning by producing a tool for sharing with children a vision of the future of their community for the administrative plans of two specific regions and attempting to apply the tool in practice.The results suggest that a tool can be developed and effective if it meets four requirements. The four requirements are as follows: 1) a tool that can be familiarized with community planning, 2) a tool that can be enjoyed intuitively by adults, 3) a tool that can be developed and used in various ways, and 4) a tool that can be used in relation to the six elements of children's behavior. The six elements of children's behavior are: 1) learning, 2) knowing, 3) thinking, 4) talking, 5) playing, and 6) moving.

    Favorable external perceptions of a region are increasingly recognized as a key factor in cultivating regional experience seekers. This study longitudinally examines university students’ perceptions of cities—specifically, which cities they like or dislike—based on responses collected in an introductory urban planning course. The findings suggest that cities labeled as "disliked" are often chosen based on vague impressions rather than personal experience. Moreover, traditional tourist destinations such as Kyoto and Kamakura are increasingly viewed negatively due to issues like overtourism. In addition, the process of self-questioning the learner's own perceptions about cities would be the foundation of their deeper insight into cities in urban planning education, particularly for beginners.

    This study aims to elucidate the current conditions, challenges, and related factors surrounding public-private partnerships (PPPs) in reconstruction urban development projects in areas affected by the Great East Japan Earthquake, including regions impacted by the Fukushima nuclear disaster. Furthermore, the research seeks to offer policy recommendations for enhancing the implementation of PPPs in future reconstruction efforts. To achieve these objectives, data were collected through questionnaires administered to local governments. The analysis involved a comparative assessment of urban development projects with and without reconstruction components, as well as cross-regional comparisons. As a result, it was found that regional differences were larger than the differences between reconstruction projects and non-reconstruction projects, and that PPPs were more difficult to consider and implement in Fukushima than in Miyagi and Iwate, and that the challenges were greater in Fukushima than in Miyagi and Iwate.

    This study documents an innovative experiment in participatory urban visioning conducted in Mae Hia Town, Thailand. The workshop utilized LEGO® Serious Play® (LSP) methodology integrated with Imaginary Future Generations (IFG) techniques to enable diverse stakeholders to articulate their personal and collective urban imaginaries in tangible forms. Forty participants representing five key stakeholder sectors collaboratively envisioned Mae Hia's past (2014), present (2024), and desired future (2044) states. The findings suggest that LSP can serve as policy instruments for activating civic agency, co-producing knowledge, and embedding context-sensitive planning capacities in secondary cities. This approach offers valuable insights for urban planners working in contexts where traditional engagement methods struggle to foster meaningful dialogue across diverse groups and generations of residents.

    In Kurashiki, a number of initiatives related to nighttime landscaping have been implemented. However, in recent years, the use of nighttime landscaping has rapidly transformed the area into a tourist destination, and the balance between residents living in the area and tourism is becoming unbalanced. The purpose of this study is to assist in the future development of nighttime landscapes. During the period of nighttime landscape development, nighttime lighting projects were completed in a short period of time, and the foundation of the nighttime landscape was established. However, the nighttime landscape with dramatic lighting highlighted the progression and hollowing out of the tourist area. In the period of nighttime landscape utilization, the balance between tourism and daily life became more important. In the future, it is also very important how to improve the living environment in the development of nighttime landscapes.

    Streets along greenways are being utilized in an integrated manner with stores and plazas using pedestrian malls. This study examines buildings along five greenways in terms of (1) landscape characteristics and (2) utilization of greenways by pedestrian malls, with the aim of contributing to the development and utilization policies for greenway spaces. (1) No rooftop greening, wall greening, or other forms of surface greening have been implemented. In cities with many residential buildings, it is difficult to form an integrated landscape with greenways. It is important to show specific greening areas and greening methods that are appropriate for the use of buildings and the actual conditions. (2) It has been confirmed that initiatives to make the greenways more accessible to citizens and proactive promotion of events will bring about a lively atmosphere not only along the greenways but also in the surrounding areas.

    In this study, we focused on Kansai Region in central Japan, and constructed digital point vegetation data from 1950s land-use maps in paper format. Then we overlaid it with 1980s and 2000s vegetation data in vector format and identified vegetation change patterns its distribution characteristics. As a result, the patterns of vegetation change can be classified into 66 categories, and the 12 most frequently identified patterns indicate that there are two major trends of change in the area: a) from pine trees to other vegetation and b) urbanization. In the granite-based mountain areas, especially on steep slopes, pine forests have remained since the 1950s, but in other areas, the vegetation has shifted from pine to Quercus serrata due to pine wilt disease and other factors. However, there are only a few sites where pine forests have been replaced by evergreen forests. These uneven and limited distribution of evergreen forest conversion suggests that dynamic forest change may be occurring in these areas, influenced by land use change from rural to urban areas, rather than unidirectional vegetation succession as has been discussed.

    People are becoming increasingly isolated as connections between people diminish in society, and open innovation, which connects companies with each other in the face of global competition, is becoming increasingly important. Against this backdrop, a movement has emerged in multi-tenant large-scale logistics facilities located between highway interchanges and residential areas in the suburbs of large cities to support community building by involving the surrounding residents, and to promote innovations among the companies occupying the facilities. This paper reports on the background behind these developments and what is actually being done in such a logistics facility, and finally consider the implications of these activities for community buildings including “area management”.

    In recent years, research and development of eVTOL has been progressing around the world, and in Japan, activities such as demonstration tests and route design for its introduction have begun in various regions. This study focuses on the nature of requirements for eVTOL route setting, and summarizes the trends in the perception of each requirement based on a questionnaire survey on route selection. It was suggested that requirements such as DID are often viewed as an additive factor regarding area considerations. Since requirements are perceived differently in different regions, it is important to identify and focus on requirements that can be the axis of discussion in each region.

Therefore, a logistic regression analysis was conducted to identify the locations where traffic accidents are most likely to occur. The analysis revealed the following two points.1. Effective traffic accident reduction measures differ depending on traffic volume, type of accident, and driver age group. Therefore, it is necessary to consider measures according to the environment of the roads where we plan to reduce accidents.2. Land use ratio and population distribution also affect the accident likelihood.

    Redevelopment of public bathhouse (sentō) sites in Japan shows unique trends, often utilizing existing facilities for commercial purposes. Due to the rise of in-home bathing and aging infrastructure, sentō are rapidly disappearing. This study analyzes the relationship between the surrounding environment and the redevelopment of closed sentō sites. The results suggest correlations linked to specific redevelopment trends and the unique characteristics of these culturally significant spaces.

    The purpose of this study is to analyze the results of the walkable pilot program “Hot Izunaka” implemented in Izunokuni City, Shizuoka Prefecture, which promotes people's staying and rambling activities by creating multiple spaces to stay simultaneously, and to clarify future issues. The pilot program achieved a high turnout of 134 participants over the three-day period, with approximately 80% of the participants visiting all five stay-type spaces. While the stamp rally effectively promoted circulation, the duration of stay was short and visits to areas other than the designated ones were limited. This study revealed the importance of planning according to the characteristics of the location, environmental comfort, and coordination with surrounding facilities in order to engage more people, encourage them to rambling around a city, and revitalize the community.

    This report focuses on business intelligence (BI) tools, which have been attracting attention in recent years and are being applied in our society. In particular, to discover the potential of BI tools in landscape urban planning, I examined the usefulness of a system for collecting landscape elements through machine learning. The results suggested that gathering information by using BI tools bridges multiple analytical tools and is particularly effective in terms of visualization. Object detection using machine learning, as applied in this report, resulted in a huge number of cropped images, so a framework for clearly classifying and organizing the results is necessary. Therefore, linking with a BI tool that can instantly store data seems to be an essential mechanism for creating a series of image collection systems. There were some obstacles, such as the need to spend a lot of time adjusting data storage at the stage of visualizing the results of the analysis. In the future, I intend to extract these individual issues and try to improve the system. I will also collect more information on BI tools in an effort to contribute to the social implementation of landscape research.
