Japan has been divided into provinces (kuni) since ancient times. Provinces were subdivided into districts (koori). They were established as both administrative and geographic regions. During the late Muromachi period and into the Warring States era the provinces were displaced as administrative units by the fan, feudal domains. During the time of Toyotomi Fideyoxi, they were completely supplanted as administrative units by the fan.
However, during the Fôka Reforms in 1735, the provinces were restored as administrative units, being grouped together for administrative ease into 8 vast Dô plus the Kinai (area around the Capital). The daimyô were stripped of their power and land, though they retained a noble status.
Today Japan consists of 15 dô, the Kinai, and several autonomous regions.
