The Fuhanken Sanchisei (府藩県三治制, "Fu, Han and Ken three-tiered Governance System") was the subnational government structure in early Meiji Japan. It lasted from the Boshin War, the start to the Meiji Restoration, in 1868 until the replacement of all remaining feudal domains (-han) with prefectures (-ken) in 1871. During this period, prefectures, urban prefectures (府, fu) and rural prefectures (県, ken), controlled by the new central government, and daimyō Domains (藩, han), still under their pre-restoration feudal rulers, formed the primary administrative subdivisions of the country. The exact numbers varied continually as adjustments to the feudal territorial divisions, mergers and splits started to take up pace, but very roughly there were about >250 -han and about <50 -fu/-ken in total dur
