A town (町 chō) is a local administrative unit in Japan.  It is a local public body along with prefecture (ken or other equivalents), city (shi), and village (mura).  Geographically, a town's extent is contained within a prefecture.

Note that the same word (町 machi or chō) is also used in names of smaller region, usually a part of ward in a city.
