These studies are to describe the process of urbanization in Tsukuba New Town from the data of our long-term surveys, and examine affecting factors and their relations to the process. This paper describes the process by two sides of urbanization, spatial and functional, and we conclude: 1)The attainment of planned migration in 80 and Tsukuba Expo 85 are two major factors. 2)The former influenced construction of the public residential district and satisfied the fundamental functions for living. 3)The latter influenced construction of the town center and enriched the higher functions for urban activities. 4)These factors didn't exert much influence on urbanization in the private lands, but this low-speed urbanization was important to correct the unbalances and shortages that occured by high-speed urbanization of the public and planned lands.

This paper deals with the urbanization process in Tsukuba New Town especially from the view of inhabitants' behavior and consciousness to this town. Through our several surveys since 1972, we found out the following facts. 1)There was developing gap between planned residential area and privately owned land before 1980. But after '80, several items indicate the improvement of living environment. 2)There are two types in the changing pattern of urbanization, one is the regular change and another is the abrupt change. Both type should be necessary to realize a balanced and acceptable urbanization.
