In local cities in Japan, the hollowing out of central urban areas has become increasingly serious. To revitalize a central urban area, it is important to entice inhabitants. Once people begin to live there, various urban functions for residence will follow, and a “community town” will be built. In this study, various questionnaire surveys and interview surveys were carried out in Toyohashi City, Aichi Prefecture. The survey results were analyzed from the perspective of both residents and housing suppliers, clarifying the existing conditions of residence in the central urban area in a medium-scale Japanese city. The findings were:
1) There are an overwhelming number of rented apartments in Toyohashi City, and the core area of the locations has shifted from the central urban area to surrounding areas.
2) Sites in the central urban area are small and not suited to condominium construction in terms of scale and shape. Furthermore, landowners' interest in land utilization has been lukewarm, and hence there has so far been a small supply of condominiums in this area.
3). Since around 2001, many condominiums have been built in the central urban area and surrounding areas. The reasons were a) relatively large plots of land suited to condominium construction have been supplied; b) Toyohashi City, which had been less successful in supplying condominiums, became a new target market; and c) a redevelopment subsidy was injected into the central urban area, which had higher land prices than in the suburbs. As a result, project profitability was ensured.
4) Most households expressing interest in residing in the central urban area are a) mainly young, single-person households wanting convenience in commuting, who had moved from outside the city and the suburbs, or had relocated within the central urban area; b) young nuclear households regarding access to public transportation and parents as important, who had relocated within the central urban area or had moved from the suburbs; and c) middle-aged nuclear.households regarding access to public transportation and shopping convenience as important, who had relocated within the central urban area.
5) Although few, there are a certain number of households who express interest in living in a central urban area. Depending on the supply of condominiums, central urban area residences may appear even in medium-scale cities such as Toyohashi.
6) Condominium residents in the central urban area often focus on urban conveniences rather than the amenities of the residential environment. However, it would be much more important to supply such amenities as spacious living areas and parking spaces for the establishment of a central urban residential area.
In small and medium-scale cities where detached homes in the suburbs are most common, central urban area residence cannot be explained only by economic reasons. It will not occur unless there are administrative supports and sincere actions of inhabitants on the basis of social necessity. The establishment of a central urban residential area depends on public opinion of the social meaning of a central urban area in the future.
Because the results in Toyohashi City and data from other cities in Japan were not sufficiently compared, the generality and uniqueness cannot be analyzed in this paper. Therefore, it will be necessary to accumulate findings from other studies to broaden our understanding of central urban area residence in medium-scale cities in the future.
