This paper analyzes the mobile retailers in Tokyo that are expected to help customers living at distant locations from retail shops. The location data of mobile retailers were collected through interviews to sales managers and examination on the internet. The data were analyzed based on a Poisson regression model. Analysis and interviews revealed that mobile retailers play a key role in providing shopping opportinities to the people who encounter difficulites in shopping such as distant and elderly people. Mobile retailers also promote social interaction between their customers. Legal regulations, on the other hand, prohibit a wide spread of mobile retailers, which should be resolved by administrations.

This paper reports on a collaborative project implemented in August 2021 between Hyogo Prefectural Hokusetsu-Sanda High School and the University of Hyogo. The two-day short-term intensive project provided an opportunity for high school and university students to study together. The results of this project can be described as follows: 1) The program assumed a form of cooperation based on an equal relationship between the high school and the university from the design stage, which allowed for enhanced educational content and appropriate division of roles; 2) Responses to the questionnaire by participating students were mostly positive; and 3) Although this project was successful, some issues need to be resolved in order to continue implementing the project and clarify any links with urban planning or Machizukuri.

Midosuji is one of the representative streets of Osaka City. In Midosuji, an orderly landscape has been formed by the continuous walls and skyline under regulatory guidance. However, in recent years, it is about to move to a new stage of interactive landscape management by the government and area management organizations through the application of local rules. In this study, we first organized the actual situation of interactive landscape management in Midosuji. Next, we conducted a field survey on the application status of local rules. Next, we conducted a questionnaire survey of local residents regarding their evaluation of the Midosuji landscape. Based on the above, we analyzed the evaluation of landscape management in Midosuji.

In this study, we defined "Landscape Management" (LM) as an approach to manage the landscape of the area by various actors, and clarified the characteristics of LM operated by Community Organization (CO) through a questionnaire survey throughout Japan. The framework of questionnaire for the analysis of LM includes indicators such as "operation of the landscape rules", "landscape formation projects", "management of public spaces", "measures for vacant houses and vacant land", "event efforts", "management of rural landscape, farmland", "management of traditional landscape, traditional events ". Second, we selected the Fujikawa-Juku, Okazaki City, Aichi Prefecture, as our target case study. Fujikawa-Juku is a local city with historical townscape, where various LM practices are carried out by CO. We analyzed the development process of LM through interviews with CO in the Fujikawa-Juku.

In this study, as an example of a new town where population is expected to decrease in the future, it aims to investigate the distribution of vacant lots and vacant houses in the Nankai Hashimoto Rinkan Rural City and to understand the issues for maintaining the new town for the future. A field survey and a material survey were conducted, and comparisons were made by smaller areas in comparison to the previous studies. As a result, it became clear that the vacant house rate is high in areas that are more than 10 minutes on foot from the elementary school. In addition, there were some areas where vacant houses were found even though the residential land was unsold. From a 20-year data survey, it was found that many of the vacant lots have been used as parking lots in a planned manner, and that the number of parking lots has not increased in recent years.

In recent years, the consolidation of police and residential police boxes has been progressing. This paper examines the relationship between the decrease in the number of police and residential police boxes, and residents’ fear of crime and crime risk perception at the city level in Japan from 2015 to 2020, using “Digital Maps 25000” and “Research and study on fear of crime.” The differences in fear of crime and crime risk perception between respondents from the cities with a decreasing number of police boxes and cities in which it was stable were determined by a t-test. The same analysis was conducted at the residential police boxes. The results showed that the fear of crime and crime risk perception in the decreasing cities tended to be lower at police boxes, and fear of crime in the decreasing cities tended to be higher at residential police boxes.

In this study, we held a learning program for junior high school students in the area using a simulation video of evacuation behavior at the time of flood damage in the Arakawa and Kamogawa basins of Saitama City. We measured change consciousness to support vulnerable people. As a result, the following became clear. 1) In the evacuation behavior simulation, by creating scenario A where you will be involved in inundation and scenario B where they will not only help themselves but also help people who need consideration as an evacuation guide, people can prepare for disasters and evacuate early. We could create an easy-to-understand material to encourage people to evacuate. 2) It became clear that holding learning program using evacuation behavior simulations is effective in raising residents' awareness of disaster prevention.

One of the problems in many local governments in Japan is population decline. This is no exception even in ordinance-designated cities, and the population will decline significantly in some cities. The population of Yokohama City differs from north to south areas in terms of its population growth. Furthermore, the characteristics of each area also differ among directions (north, south, east, and west). Therefore, if Yokohama City considers measures for population decline, it is at least important to understand the characteristics of demographics at the ward level. In this study, we clustered the characteristics of changes of populations, social populations, and natural populations based on the time trend in the wards of Yokohama City. Then, the results of the classifications were further evaluated. Finally, the characteristics of each ward were clarified, and we furthermore considered future population changes based on the results.

Kagai is a Japanese term for traditional entertainment districts. Kagai reached its prosperity from the Taisho era to the early Showa period and the middle of the Showa period. To date, no study has clarified the actual situation of Kagai in Niigata prefecture in rise period after World War II. This study attempts accurately to clarify the Ryoriya association and distribution of Ryoriya in middle of the Showa period in Niigata prefecture. Major results are as fillows. 1) There were Ryoriya associations in at least 19 districts of Kagai in Niigata prefecture in 1963. 2) In 1963, 574 Ryoriya were members of the prefectural Ryoriya associations, of which about 20% are still open. 3) As for the distribution tendency of Ryoriya, about 90% of the areas were concentrated in a certain area, and most of them tended to be located in the old shopping streets and around the station.
