Out of the nine 'fu' under the Fu-Han-Ken Sei (the domain and prefecture system), six 'fu' were changed into 'ken' under Haihan-chiken (abolition of feudal domains and establishment of prefectures) published in 1874, which resulted in three 'fu,' which remained in the prefectural system under Meiji Constitute.
府藩県制の元では9つあった府が1874年の廃藩置県によってうち6府を県に改めたことで成立し、明治憲法下の府県制の下でも存続した。
