Abstract
Recently many apartment-houses are built in Sendai keeping pace with the increase of population. The apartment-houses are distributed less in the central part of the city, and more in the old residential areas and the new residential areas to the north, the east and the southwest of the outer zone of the city. They receive many immigrants from outside the city. One of the recent trends is the encroachment of the apartment-houses new residential areas. It is because high landvalue in the inner part of the city is prohibitive to the apartment-houses. The conclusion obtained from the analysis of the distribution of apartment houses is compatible with the concept of segregation by Louis Wirth.
