This study examined an alternative to the Japanese compact city approach to urban sprawl by evaluating a scenario for the smart decline. The smart de-cline scenario comprises planning and design methods intended to satisfy residents’ lifestyle needs in a context of gradual population decline. The research method was scenario planning using the case study of Ibaraki city in the Northern Osaka Metropolitan Area. Four scenarios were tested: (1) scenario in which vacant land is used, (2) scenario to leave from the suburban, (3) scenario to inhabit around transit stations, and (4) scenario to increase mass transit. The scenarios were analyzed using the Walkability Indicator, which was verified through correlations with the regional evaluations and the daily behaviors of a sample of respondents to a survey. The scenario in which vacant land is used was found to be the most effective as the smart decline for sprawl areas.
