Outline of Final Research Achievements	This study focuses on the issue of urban planning in the age of shrinking cities, where a change is desirable from the traditional planning aimed for regulations to the planning with more flexibility due to the decline of the pressure of development and the increase of unused land. To that end, this study examined people's psychological evaluations of residential environments and convenience, and attitudes toward mixed land use in residential areas, through a questionnaire survey administered to 4,000 residents in four wards of Tokyo (Setagaya-ku, Suginami-ku, Taito-ku, and Sumida-ku). Based on their responses to the questionnaire, the effects of performance-based regulations and the possibility of applying them to the practice of urban planning were discussed.
