This study seeks to determine the flow line area ratio by department and the general regression equation for the flow line area ratio.

As a result of the study, they were able to determine the flow area ratio of the hospital to be 30.3%, as well as the flow area ratio of each department and the flow area ratio of each floor according to the combination of departments. Departments such as general outpatient, wards, physiological laboratories, and emergency services have a positive impact on the flow area ratio.

In recent years, non-institutional places known as “Machi no Ibasho” have emerged across Japan.　This paper examines the “Ibasho House” in Ofunato City, Iwate Prefecture, where the author conducted fieldwork, by analyzing how people perceived its guiding principle. The aim of this study is to explore the significance of principle in the operations of “Machi no Ibasho.” Through analysis of the authorʼ s fieldnotes, three meanings of principle in “Machi no Ibasho” were identified: as a catalyst for involvement in operations, as influencing operations by resolving the “gap” between principle and operations, and as a clue for reflecting on operations.

Social problems arise when individuals with sensory sensitivities or developmental disabilities face restrictions at school or work due to overwhelming external stimuli. Online tools and telework can help these individuals engage with society from familiar settings. However, face-to-face interactions remain essential. This study explores the effects of a Quiet Room on individuals with sensory sensitivities by analyzing changes in tension levels through heart rate measurements and questionnaires. By comparing participants with and without sensory sensitivity, the research highlights the potential of Quiet Room in helping these individuals navigate social interactions while maintaining appropriate boundaries.

This paper aims to clarify the actual conditions of commercial zone designation in major provincial cities. As an initial analysis, this study examines the trends in commercial zone designation across 40 cities and considers the relationship between designated zone size and various data. And, focusing on 10 cities with distinctive commercial zone designations, this study analyzes the authorities’ policies and the reactions of local stakeholders based on the proceedings of the City Planning Committee. Through these analyses, this study aims to clarify the process by which commercial zones, as the backbone of urban structure, were designated in each city.

This study classified and statistically analyzed the urbanization status and spatial forms of 106 urban villages in Nanchang City in 1946, 1967, 1983, 2003, and 2023. Results clarified the transition from rural space to planned urban space in urban expansion process. Under urban planning and economic development, urban villages have evolved from spontaneous villages to a mixed grid pattern and ultimately a complete block. Historical urban planning policies, especially those before 1983, played an important role in urban village formation. The public facilities during the planned economy period were confirmed to contribute to urban-rural spatial integration in Nanchang City.

In recent years, cooperation between local governments and residents has become essential for managing abandoned railway sites in rural areas facing depopulation and limited resources. Focusing on the Nagano Dentetsu Yashiro Line, this study aims to clarify local government maintenance strategies and the actual patterns of provisional use by residents. Through field surveys and interviews, it reveals how these uses are shaped by surrounding land use and local conditions, offering insights into current challenges and the potential for resident involvement in future site management.

This study clarifies location structure of depopulating villages in Urbanization Control Area and considers deregulation approach of Development Permission (DP) in Toyohashi City. Toyohashi has both villages of depopulating and non-depopulating. The former ones are located in northeast, southeast and southwest parts of city as one body. They are inconvenient especially for shopping environment of daily commodity and it’s one of main reason for depopulation. Housing developments have decreased since 2001 and drastic increase of vacant houses is predicted in near future. As deregulation approach of DP, this study investigates five pattern cases for five villages with different conditions.

This study explores the differences between women and men in the relationships of perceptions of post-disaster living conditions. The research area in this study is Kirime area of Inami Town, Wakayama, Japan. To illustrate the relationship between residents’ anxiety about living conditions in the early recovery phase and demand for measures to respond to the problems, a questionnaire survey was conducted on residents in the research area. Results indicated that the main factor of the perception of post-disaster living conditions in women group is mental stress, while the main factor in men group is physical health.

Urban greening has gained significant importance recently, leading to the development of systems that immediately increase floor area ratios based on greening scale to encourage voluntary efforts by private real estate developers. However, the long-term benefits of greening remain largely empirical. This study proposes a mathematical model to analyze the optimal greening rate for maximizing profits in real estate development, providing systematic insights. Additionally, through a case study of Tokyo’s comprehensive design system, the model’s effectiveness is validated, elucidating the long-term benefit characteristics of greening.

This study analyzes the management styles and issues of area-management organizations through advertising in the Special District for Urban Regeneration in the Tokyo metropolitan area. Three key points are discovered. First, criteria must be updated flexibly in consideration of coordination between landscape administration and area-management organizations. Second, businesses must promote understanding regarding advertisement posting through collaboration with local officials. Third, independent review standards must be established for advertising in addition to utilizing local schemes and conducting social experiments.

This study examines the landscape characteristics of a historic wholesaler district in Nihombashi, Tokyo, based on onsite survey of 135 buildings along two key streets. The results highlighted current features including low- to middle-rise buildings, wide frontages, continuous projecting signboards and awnings, and business overflow into setback areas, which were observed especially in the district’s central part. Differences between streets were shaped by street width and building scale. While current planning framework keeps row of shops, maintaining the character of small-scale storefronts amid expected high-rise redevelopment remains an issue. The study identifies key challenges in managing urban business cluster landscapes.

Many land use management ordinances (LUMOs) have been enacted since early 1970s. This study clarifies LUMO revision to discuss how it adapted against socioeconomic change in long term. Through nationwide complete survey including questionnaire and interview, this study concludes as follows: 1) totally only 36.9% were revised in spite of municipality officers’ problem awareness, 2) while LUMO is classified into three types, type setting land use basic plan has been revised effectively, 3) even in the case of most progressive ordinance which makes original land use control system, collaborative enforcement with Urban Facility Location Plan is not perfect, etc.

We arranged how the definition of the role of CMR changed after the CM system was introduced into Japan in the 1990’s. And then, we analyzed 150 specification documents of construction projects by local governments to clarify the actual situation of the role of CMR since 2015. As a result, it was revealed that local government often asked CMR for the agreement with various project stakeholders in addition to the standard duties of projects using the CM system, and that CMR accepted the duties of the basic concept stage and various survey operations in projects not using the CM system

The purpose of this research is to clarify the possibility of using vacant detached houses which have a low distribution rate as spaces for personal hobbies. As a result of survey, we found that there was a high demand for those spaces. Furthermore, assuming that hobby spaces are development first by people with a high willingness to pay, it was found that there is a possibility that the use of vacant detached houses as hobby spaces will increase if low-cost vacnt houses don’t require “insulation renovations and soundproofing” or “insulation renovations and earthquake resistance renovations”.

This paper analyzes historical architectural books “KIWARI-SHO”, entitled “Torii no Myoumoku”, and presents new evidence that sheds light on the theoretical transition from the Middle Ages to the early modern period. The first part focuses on interpreting previously unstudied versions of “KIWARI-SHO” that have remained unknown to scholars in the academic field, in order to gain a clearer understanding of the text. The second part compares medieval and early modern texts to trace the transition, with particular attention to the shift from concrete to abstract characteristics.

This paper is the 1st paper of architectural study on viharas of Buddhist caves of Kanheri, in India. Firstly, the results of measurements conducted on 69 examples of early viharas were presented, including plans of caves not previously featured in existing literature. Additionally, the differences in the sizes of the main components of early viharas, the hall and the chamber, in terms of area and ceiling height were analyzed, and the intended purposes of the hall and chamber were discussed. Based on these results, typologies of the floor plans of each viharas composed of hall and cell(s) were presented.

This study aims to clarify Schindler’s and Neutra’s vision of the living environment regarding stay and rest with the seating furniture in the houses they designed. By transferring the precedent studies’ results into the vocabulary-based analysis method, their architectural writings were screened from the perspective of seating furniture. The roles of seating furniture in daily life were examined through diagrams of the interrelationship structure of related concepts in each architect. The results suggest a shift in how architects came to appreciate life in Southern California.

This research contributes to the strategic utilization of under-railway spaces in shaping diverse and dynamic urban environments.

This study aims to clarify the characteristics of urban spatial image used to grasp the complex city of Tokyo as expressed in photo-based street guidance. By collecting materials on the internet, the urban spatial image of photo-based street guidance was analyzed from the following aspects.

Landmarks and instructions in each frame photograph were examined. Then, photo sequences were categorized. Finally, the distribution of sequences around stations was analyzed.

The above analysis revealed that photo-based street guidance conveyed unique urban spatial image around stations and that experiential image is formed in relation to the density and axiality of the urban structure.

This study examined how land owned by the British and other wartime enemies of Japan was treated during World War II, with a focus on the area of Kitano-cho and Yamamoto-dori 1-chome to 3-chome. Such foreign-owned land became management property, immediately following Japan’s entry into the war. However, holders of Japanese citizenship, including naturalized citizens, were able to escape the official property prohibition. In addition, the Japanese government treated India differently from Britain and removed Indians from its list of enemies. As a result, land acquisition by former British citizens who were recognized as Indians continued throughout the war.

Since the pre-war period, city planning administration had consistently and strongly planned to promote its projects through public organization-enforced land readjustment, and during the wartime period rapid expansion occurred, primarily in new industrial city planning. In particular, local cities that had previously delayed city planning projects had high hopes for a breakthrough in the situation, and Sendai was a typical example. Through the discussion in this paper, it is considered that wartime city planning inherited the project system formed in the pre-war period, and that the coercive nature that characterized it was already in place at that time.

Recent advances in deep learning enable automated building detection from remote sensing data. However, building detection typically requires costly high-resolution imagery, limiting scalability and applicability. This study proposes an integrated framework using 10 m resolution open-access Sentinel-2 data for detection and attribute estimation of buildings. Regions are classified based on building characteristics, and a multitask U-Net optimized for each region performs segmentation and building count estimation. Building objects are extracted first, followed by the estimation of structural type and construction year. Finally, earthquake-induced collapse simulations demonstrate the practical utility of the resulting data for urban planning and disaster prevention.
