Tokyo 7th district was a constituency of the House of Representatives in the Diet of Japan (national legislature).
For the election of 1976, Western parts were split off to form the new 11th district.
As of 1993, the 7th district consisted of the cities of Tachikawa, Musashino, Mitaka, Akishima, Koganei, Kodaira, Higashimurayama, Kokubunji, Kunitachi, Tanashi, Hōya, Higashiyamato, Kiyose, Higashikurume and Musashimurayama.
In the 1986 election, the LDP stopped nominating two candidates and Kiyoshi Ozawa (later minister during the coalition with the Socialist Party) became the party's only candidate in Tokyo 7th district.
Since the electoral reform of 1994 the area is distributed over several single-member districts.
