This study aims to understand the phenomena of population recovery and construction of high-rise condominiums in urban centers of mid-sized local cities. From 2000 to 2010, population of the downtowns had recovered in 27 out of 45 case study cities, while that of downtown peripheries had shrunk in 42 cities. High-rise condominiums had been constructed and the household living in them had increased in the downtowns and downtown peripheries in all of the case study cities, but the household living in detached houses had decreased in the downtowns and downtown peripheries in almost all of the cities. Therefore, downtown peripheries, of which detached houses constitute a majority, had taken on population decline. Some downtowns of which detached houses constitute a majority have the same cause.
