The purpose of the paper is to find out trend and primary factors of change in commuting distance in Japanese metropolises for the period of 1965-2000. We distinguish the periods by change in the number of workers and commuting distance. During 1965-1970, commuting distance is increasing remarkably for all metropolises according to the spread of commuting boundary. During 1975-1985, increase of commuting distance is still represented that is caused by increase in the number of workers. During 1985-1990, the hasty increase tendency appears to all metropolises affected by bubble economy. During 1990-2000, only decrease tendency of commuting distance appears to Keihinyo (Tokyo) and Keihanshin (Osaka) metropolises, but the central area shows up increase of commuting distance.
