Name changes
[edit]- 1928 – Chōfu village (Chōfu-mura) in Ebara county becomes a town and is renamed East Chōfu town (Higashi-Chōfu-machi; note: there had been a Chōfu-machi/Chōfu town in North Tama county, Kanagawa since 1889. There had also been Chōfu-mura/Chōfu village in West Tama county (Nishitama-gun), Kanagawa since 1889. North (Kita-), South (Minami-) and West Tama counties (Nishi-Tama-gun) were transferred from Kanagawa to Tokyo in 1893, so that there were three different municipalities named "Chōfu" (two -mura, one -machi) in Tokyo until 1928. Eventually, East Chōfu town, Ebara became part of Tokyo City in 1932, Chōfu village, West Tama became part of Ōme city in 1951 and Chōfu town, North Tama became part of Chōfu city in 1955)

- 1970 – Yamato town (Yamato-machi) becomes a city and is renamed Higashi-Yamato-shi ("East Yamato city"; note: there was already a Yamato-shi/Yamato city in Kanagawa since 1959. Geographically, Higashi-Yamato-shi lies almost exactly north of Yamato-shi; the Higashi/"East" (東) represents the Tō (東) in Tōkyō – Higashi-Yamato-shi is "Tokyo's Yamato City".[14] There had also been a Yamato town in Saitama which was renamed as Wakō city in 1970.)
- 1970 – Kurume town (Kurume-machi) becomes a city and is renamed East Kurume city (Higashi-Kurume-shi; note: there was already a Kurume-shi/Kurume city in Fukuoka, one of the first 40 cities of Japan in 1889/90.)
Notes
[edit]- There are several technical differences between two types of mergers: hennyū gappei, "incorporating/absorbing mergers", where one or several municipalities merge into another that continues to exist, and shinsetsu gappei, "new establishment mergers", where two or more municipalities dissolve to establish a new one which may bear the identical name of one of its predecessors. In the latter case – regardless of naming –, for example, municipal institutions (mayor and assembly) lose their mandates, and new elections must be held.
- County/district governments were dissolved in the 1920s following a 1921 initiative by the Hara Cabinet and are not mentioned in the list after their abolition as administrative units.
