    Global ESG initiatives are becoming more active. Third-party certification system is used as a method to disclose the results as non-financial information. Although there are many studies on third-party certification, there is no research on their certified results. Therefore, we selected two certification systems, SEGES and ABINC, which evaluated for creating and maintenance corporate green spaces in Japan, and studied on their cases obtained certifications. We The number of certifications obtained is increasing year by year. In order to get a bird's-eye view of performance, we categorized them by whether they would own land or buildings (Type I, II) or sold them (Type III). If they were owned, they were classified into whether they were used for their own business (Type I) or used for rental business (Type II). As a result, it was found that the ownership Type I and II preferred SEGES, which evaluates the comprehensive value of green spaces. And the certification renewal rate of two systems was low for type III. With the publication of the TNFD, it is expected that the movement towards non-financial information disclosure will become even stronger, but whether the third-party certification system will be able to continue to respond to this trend remains to be determined by research into the awareness of companies seeking certification.

    To understand the current situation of elementary school children's commutes in Japan, an online survey targeting women aged 20-49 with children attending municipal elementary schools was conducted in the fall of 2023. This survey garnered 6,000 valid responses, revealing that 82% of children walked to school and 67% walked home daily, with walking being more prevalent in larger cities. Besides walking, family car rides were the most common mode of transportation, although after-school program operators often directly pick up the children. Less than 2% of the children used school buses more than 11 days per month for both arrival and departure. A significant number of children commuted with peers from their neighborhoods, yet 15% walked to school and 11% walked home alone. In terms of independent mobility, 77% were allowed to walk home by themselves, but only 15% were permitted to travel outside their school district. Parents identified risks such as strangers during commutes and traffic accidents and heatstroke outside of commuting times.

    The challenges of a declining and aging population drive the shift to more intensive urban structures. The importance of sub-centers is also increasing due to the diverse ways of living and working in the post-covid(19) world. Based on these backgrounds, this study aimed to identify the results and issues of the “RENOVATION KOBE” project, which aims to create a comprehensive space around a subcenter station based on the premise of a multi-pole, decentralized urban structure. To clarify the actual situation, we surveyed private businesses involved in supporting the utilization of the plaza. “RENOVATION KOBE” is seen to have PR effects on citizens and to induce urban functions. Still, it became clear that the initiative is unclear and relies heavily on the corporate efforts of business operators.

(2) The largest number of core cities have no specific method of notification or distribution about countermeasures for food allergies. Many of them also do not emphasize variation in stocks, and the total dispersion of the 2-4 components, which are from the administrator's perspective, is about twice the dispersion of the 1 component, which is from the party's perspective. (3) Core cities should announce that they have already considered patients with food allergies. They should also take countermeasures from the point of view of the people concerned.

    This study focuses on evaluating the landscape of the Fukurogawa River in Tottori City, Japan, considering its historical changes and current maintenance. The study used methods such as green visibility analysis, profile analysis, and principal component analysis to evaluate the impact of various attributes on landscape perception. Key findings revealed that walkability, friendliness, and greenery significantly influence people’s impressions of the landscape. The research highlights the importance of integrating social and functional aspects of urban spaces with natural environmental qualities. It was found that even areas with high green visibility require proper vegetation management and sidewalks to have a positive impact. While the research was based on a limited number of photographs and respondents, the study suggests that broader future research could help to develop more universally valued and effective river green spaces.

    The study examines the location and development of nine local industries in Shiga Prefecture, particularly focusing on the textile industry in Shin-Asahi-cho, Takashima City. This area has been historically characterized by garment weaving, industrial fabric weaving, and yarn spinning. However, recent challenges such as succession shortages and declining demand have led to business contractions, prompting some individuals to cease operations, resulting in inactive factories scattered throughout the region. Through investigating the remaining wooden textile factories, the study reveals their unique features and locations, along with examples of repurposing post-closure, including adapting former textile factories for different uses, such as warehouses, and utilizing operational textile factories as warehouses. While previously overlooked as scenic resources, the study identifies the potential for leveraging the spatial resources of Takashima textiles.

    To achieve decarbonization by 2050, the Japanese government is calling for improved energy performance in new buildings. In particular, the central Tokyo area has a high concentration of aging small-sized buildings, which need to be reconstructed or renovated to improve the efficiency of their energy use. However, building owners are faced with the high cost of ZEB and energy efficient renovations. Therefore, there is a need to implement reconstruction or renovation at an appropriate time, and to improve business feasibility by providing incentives. The purpose of this study is to clarify how environmental measures should be introduced and how business schemes should be constructed to achieve decarbonization. As a result, it is clear that early reconstruction and energy-saving retrofitting will improve the environmental performance of the district, and that it is possible to introduce environmental measures that ensure business feasibility by utilizing the revenue from the proposed deregulation of floor area ratio.

    In recent years, urban revitalization projects involving the conversion or removal of elevated structures in urban centers have been actively undertaken. Their realization and effects take a certain amount of time to be reflected in the spatial planning of the surrounding area. In this study, using The Bentway in the City of Toronto as a case study, we analyze the impact of a project that realized the conversion of an elevated highway into a public space underneath in a short period of time by a charitable foundation on the spatial planning for the surrounding district. The analysis shows that before and after the realization of the project, the positioning of the elevated highway in spatial planning changed from a barrier to a place of potential. In addition, by engaging with organizations in the surrounding neighborhoods through various programs, the space of The Bentway project itself also changed its positioning from a hub of public space to a public laboratory.
