Gokishichidō

thumb|upright=2|Regions in the 8th century (see below for modern Japanese prefectures) was the name for ancient administrative units organized in Japan during the Asuka period (AD 538–710), as part of a legal and governmental system borrowed from the Chinese. Though these units did not survive as administrative structures beyond the Muromachi period (1336–1573), they did remain important geographical entities until the 19th century. The Gokishichidō consisted of five provinces in the Kinai () or capital region, plus seven dō () or circuits, each of which contained provinces of its own.
