Abstract
This study examines how large-scale urban development accompanied by deregulation impacts the composition of population and housing, and whether gentrification phenomena are occurring, focusing on four Urban Renaissance Urgent Redevelopment Areas in Tokyo: Shinjuku, Akihabara-Kanda, Osaki, and Shibuya. As a result, a rapid increase in population was observed in three areas excluding Shibuya, particularly among the younger generation. In terms of housing composition, the number of single-family homes decreased, while multi-family residences increased. Regarding ownership, the ratio of owned to rented properties varied by area. Characteristics of gentrification, such as the upscale transformation of housing and the increase in economically affluent young residents, were confirmed. In Shinjuku and Osaki, it is believed that the supply of large-scale condominiums due to deregulation was a direct cause of gentrification. On the other hand, in the Akihabara-Kanda area, while it's hard to say that urban development resulting from deregulation was the direct cause, it is conceivable that the expectation of large-scale redevelopment attracted medium-scale condominium development. These findings suggest that urban development with deregulation has the potential to cause gentrification, but whether it is a direct cause varies by area. Additionally, the nature and impact of gentrification also vary depending on the characteristics of the region and development.
