What is the term for the political units of Japan?

Answer 1

In Japan, there were many clans, or extended families which made up the political units. They practiced religious rituals together, lived together, and were the unit of political life. The Taika-era reforms of the 7th century established the ri as the basic social and economic unit and the gun as the smallest political unit to be governed by the central government. The gun were grouped to form more than 60 kuni provinces, the largest political units, which were ruled by governors appointed by the central government. Each kuni was composed of maritime plains, interior basins, and mountains to constitute a more or less independent geographic entity. Several adjacent kuni that were linked by a trunk road or a convenient sea route were grouped into a dō, the term signifying both the route and the region. The core region of the country was called the Kinai which is the land adjacent to the shifting imperial capitals.
