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.

Notesedit
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.
