History
Under the
Ritsuryo system, Tama District was part of
Musashi Province. The provincial capital was at Fuchu. The provincial temple (''kokubunji'') was at Kokubunji and the principal shrine (''ichinomiya'') was at Tama.
Western Tokyo previously consisted of three
districts. Nishitama District (whose name literally means "Western Tama") encompassed the present-day cities of Akiruno, Fussa, Hamura, and Ome in addition to the four towns and villages that are now in the district. As municipalities are promoted from town or village to city status, they leave the district. Thus the cities named are no longer part of Nishitama District.
Minamitama District ("Southern Tama") covered the area now occupied by Hachioji, Hino, Inagi, and Machida. With the formation of Inagi in 1971, the last city, the district ceased to exist.
Kitatama District ("Northern Tama") consisted of the locations of the present-day cities of Akishima, Chofu, Fuchu, Higashikurume, Higashimurayama, Higashi-yamato, Kiyose, Kodaira, Koganei, Kokubunji, Komae, Kunitachi, Mitaka, Musashimurayama, Musashino, Nishi-tokyo, and Tachikawa, as well as some land now in
Setagaya. With the establishment of the city of Musashimurayama in 1970, Kitatama District ceased to exist.
