This paper reports the research result carried out as the development research of our previous research to clarify the rent formation mechanism in Japan. First, we developed building micro geodata that recorded the spatial distribution of about 60 million residential buildings throughout Japan. In addition, we developed the database that can evaluate the value of about 11 million rental apartments and condominiums in Japan by giving them information on about 400 types of rent formation elements. Moreover, by clustering the database and performing sparse modeling on each cluster, we developed a method that clarifies rent formation factors that contribute positively or negatively to rent. As a result, as a nationwide trend, population dynamics around the property and the fullness of function of property contributed positively to rent formation. On the other hand, disaster risk does not affect rent formation.

This study aims to spatially investigate the pedestrian wind environment in the village located on Ogi island in the Seto Inland Sea, Japan. Then, Computational Fluid Dynamics (CFD) simulations were performed to analyze the effects of village morphology such as stone retaining walls and alleys configurations, on pedestrian wind environment. The wind speeds in alleys was relaxed owing to its narrow width in winter season and the location of leeward of a mountain. Then, the spatial distributions of exceedance probability for wind speed to contribute to wind potential maps were estimated.

In this research, we focus on the risk of unused vacant houses in vacant rental housing, utilizing the information on registered houses of the new housing safety net system, and grasp and analyze the actual situation. As a result, the vacancy continuation period of registered houses is about 10 months on average, about 10% is vacant for more than 2 years, the longest vacant room lasts for 6 years becomes clear. By the quantitative analysis, it is revealed that the risk of becoming unused vacant houses is concerned in those rental houses in major metropolitan areas, as the rental housing is far from the station, and the rental housing with a large residential area has a longer vacancy duration.

The examination of the function and the meaning of the black doors found in Japanese folk houses was the starting point for this research. Through previous researches focusing on Japanese rituals, we considered the ecstasy over rituals as one of the true natures of dwelling spaces. We conducted field surveys focusing on dwelling spaces in settlements that still have traditional rituals. Thus, we discovered that the Japanese dwelling spaces not only incorporate rituals such as traditional festivals, but also semiotic rituals such as black doors. The ecstasy over rituals brings sharp and subtle tension to the dwelling space.
