List of Provinces of Japan
The List of Provinces of Japan changed over time. The number and borders of provinces evolved from the 7th century through the Meiji Period. In the 1870s, the provinces were replaced by prefectures.
The traditional way of parsing the land of Japan was "five provinces and seven circuits" (go-shichidō).
The traditional five core provinces of Japan were called goki.
The traditional seven core circuits of Japan were called shichidō.
