Administrative divisions in Yamatai

Due to the sheer size of the Empire of Toishima, the nation as a whole have been split into several levels of administrative divisions since Miyako was first colonised. The constitution of Toishima provides for five levels of local government: planets, provinces, prefectures, cities and towns.

While the government has oversight over planets and provinces, prefectures, cities and towns typically fall under the jurisdiction of their home provinces, which are largely autonomous.

Provinces
Main article: Province

Provinces are semi-autonomous constituent political entities that share their sovereignty with their home planet and the Government of Toishima. The provincial governments are entrusted with the care of the people within their territories and the production of materials and goods as per planetary government-set quotas. Provinces are also able to muster a limited armed force to defend themselves from internal and external threats.

States are further divided into prefectures or prefecture equivalents, which may be assigned some local governmental authority but are not sovereign. Prefectural structure varies widely by state.
