  <p>This paper analyzes the records and the future policies of 1,177 cities regarding the downsizing of commercial zoning areas to examine methods of revising land use regulations to maintain a lively city center. The results revealed the following points: First, commercial zone areas have expanded even as commercial demand has declined. Second, 15 cities have reduced commercial zoning by more than 5ha. Third, only a few cities have planned to reduce or revise commercial zoning in the future, but in those few cities, the zoning was reviewed based on their future land use demand. These findings suggest the need for a clear technical standard for the future operation of appropriate zoning.</p>

  <p>Nowadays, people's “Ibasho” exist not only in physical space but also in cyberspace, but it is not clear what kind of “Ibasho” people have, including in cyberspace. The purpose of this study is to clarify the aspect of people’s “Ibasho” formed in cyberspace and physical space especially focusing on the characteristics and the psychological aspect of “Ibasho”. This study found that the psychological function of “Ibasho” differs depending on the type of “Ibasho” classified into four categories: cyberspace / physical space, personal / social, and what kind of place it is.In addition, based on the results, this study proposes eight points that make a difference between the "Ibasho" in cyberspace and physical space.</p>

  <p>This study focuses on an aging single-family neighborhood in a suburb of Fukuoka City. The purpose of this study is to clarify the factors that affect the actual situation of building renewal and the likelihood of building renewal due to differences in housing supply methods. We found that building renewal is more likely to occur in neighborhoods built by a method in which only the land is sold (a) than in a method in which detached houses and land are sold at the same time (b). In addition, it was found that (1) the flexibility to change the lot size, (2) the location on a corner lot, and (3) the small difference in elevation from the front street had a particular impact on the likelihood of renewal. In type (b) Neighborhoods, residential rental is more likely to occur. In (a) type neighborhoods, the timing of housing construction is more diverse, and site division often occurs during rebuilding.</p>

  <p>The purpose of this study is to clarify the actual conditions of community interaction in a high-rise apartment cluster district and the role of community SNS in community interaction through a survey of actual living conditions and the use of community SNS in the high-rise apartment cluster district. The study also examines the challenges and potential uses of local SNS to promote regional exchange in high-rise apartment clusters. Specifically, we took up PIAZZA, a local SNS used in the high-rise apartment cluster area in Tokyo, and conducted a web-based questionnaire survey of its users. The results showed that 1) PIAZZA users go out frequently regardless of their attributes, but the degree of community interaction differs from person to person, and 2) PIAZZA in the area has a strong character as a place for mothers raising children to exchange information online, and its effect on actual interaction among residents is limited.</p>

  <p>With the advance of the Participatory Planning, it gets more important to improve residents' participation in city planning in Japan. This study focuses on the one of the online participatory platforms, "Decidim", which derived from Barcelona in 2020, and clarifies its actual utilization in three advanced cases in Japan. We conducted interviews with the adopters and analyzed comments on Decidim to reveal the benefits and challenges in using Decidim. In Japan, Decidim is used in various ways and purposes, and can be used to expand the scope of participation. On the other hand, it has a difficulty in being accepted by most of civil servants and residents, how to "use" it, and how to customize it. It can be said, Decidim is a tool for "empathy", not "deliberation" in Japan.</p>
