The purpose of this paper is to apply the segregation model of T. Schelling to the foreign residents in Japan. We constructed agent-based model of four group residents who have Chinese, Korean, Vietnamese and Japanese nationalities in Tokyo 23 wards. The model includes total population, number of foreign residents, land price information, location of Japanese language schools for foreigners and number of public resident complex for each ward. Each actor moves to the other area when the ratio of residents of other nationalities exceeds the tolerance of the actor and select the area due to the existence of the neighboring Japanese language school, the low official land price, the ratio of residents of the same nationality of the local government and the number of public resident complex. The result of simulation executed from 2012 to 2019 shows that concentration of foreign residents occurs in some wards, but compared to the real figures, the value tended to be too extreme. So, we built elaborated model which include number of vacant houses in the ward, ratio of technical intern trainee of each nationality, and assumption that foreign residents prefer much lower land price. The result of simulation using elaborated model fit better than former model, but discrepancy remains. This analysis is just first step to apply ABM model to foreign residents in Japan so we should add decisive factors for choosing place, assume wide distribution of actor's attributes and tolerance, and secondary movement of foreign residents to make it possible to predict the future population of foreigners.
