Rise in Vacant Housing in Post-growth Japan

Overview of Japanese Urban Transformation

This book explores how Japanese cities have transformed since the 1950s by describing housing and urban planning policies, urbanization processes, and maps with GIS analysis. It also discusses how housing vacancies have increased in shrinking Japanese cities, with case studies in Tokyo, Kyoto, Hiroshima, and Utsunomiya, and examines public–private partnerships and civil engagement to revitalize cities. Providing examples of how Japanese cities have addressed the issues of aging populations and urban shrinkage, it contributes to better decision-making by politicians, planners, local authorities, NPOs, and local communities in many rapidly urbanizing and potentially aging regions such as Asia.

Challenges of Urban Shrinkage

In the era of urban shrinkage, Japanese cities have struggled with aging populations, low fertility, population loss, and a decline in the economic base over decades. In particular, shrinkage in metropolitan suburbs and large cities (e.g., sites of prefectural government with 300 000–400 000 inhabitants) has caused serious social problems owing to the huge aging population and large areas covered. One typical problem that has emerged is an increase in vacancies in now empty and abandoned housing.
