Circuit (political division) facts for kids

Kids Encyclopedia Facts

A circuit (道 ; Chinese: dào; Japanese: ) was an historical political division of T'ang China and Japan and Korea. In Korean, the same word (; do) is translated as "province".


Emperor Taizong divided China into parts which were called "circuits".

The organization of government and geography in T'ang China were merged in provinces (tao ) which were ten natural regions. In part, Tang history is about the changing balance between the provinces and a strong central government.


During the pre-modern era, Japan was divided into a central region and seven provincial regions or "circuits", including

  • Hokurikudō (北陸道, literally, "North Land Circuit"), 7 provinces (kuni)
  • Nankaidō (南海道, literally, "South Sea Circuit"), 6 provinces
  • Saikaidō (西海道, literally, "West Sea Circuit"), 8 provinces
  • San'indō (山陰道, literally, "Mountain-north Circuit"), 8 provinces
  • San'yōdō (山陽道, literally, "Mountain-south Circuit"), 8 provinces
  • Tōkaidō (東海道, literally, "East Sea Circuit"), 15 provinces
  • Tōsandō (東山道, literally, "East Mountain Circuit"), 13 provinces

In the mid-19th century, the northern island of Ezo was settled, and renamed Hokkaidō (北海道, literally, "North Mountain Circuit").

Hokkaido did not develop as a "circuit" in the traditional way. It became a prefecture. It had a name which was different from the other prefectures because of the suffix -dō.


After the late-10th century, the province (do) was the main subdivision of Korea.
