The purpose of this paper is to statistically analyze locality in physical types and dwellers characteristics of condominium buildings in Tokyo metropolitan region, by using the 1993 Housing Survey of Japan. Main conclusions are as follows; 1) Typical physical types of condominium buildings in Tokyo central wards are high-rise buildings which contain under 50 apartment units, those of eastern wards are high-rise building of more than 50 units and estates constituted by them, and in western wards is low and mid-rise building under 50 units. 2) Early supply of condominiums in 1960s are separated into high-rise or small buildings in Tokyo wards and large-scale estates constituted by mid-rise buildings in suburbs. Large high-rise building has gradually increased and diversity of building types have been under way since 1970. 3) Most condominium buildings contains many rental dwellers and its average ratio is 30 to 40 % in Tokyo wards, regardless of building age. On the other hand, the average ratio in suburbs has decreased from around 20 % in case of older buildings constructed before 1970 to about 10-15 % after 1980. 4) Most older buildings contains many elderly owner households whose ratio is over 20% of total owner units. Single and elderly households are very common in Tokyo wards, regardless of building age, and young families who purchased used units are also common in suburban condominium buildings.
