The Kamakura-fu (鎌倉府, Kamakura government) or Kantō-fu (関東府, Kantō government) was a regional government installed in Kamakura, in today's Kanagawa Prefecture, by the Ashikaga shogunate which lasted from 1349 to 1455. It was headed by a dynasty of Ashikaga rulers called Kamakura Kubō (or Kantō Kubō). They were assisted by deputies called Kantō Kanrei traditionally chosen among the members of the Uesugi clan.
Structurally, the Kamakura-fu was a small-scale duplicate of Kyoto's government, had full judiciary and executive powers within its territories and was responsible for its military.[1] At first its territory included just the eight Kantō provinces (the Hasshū (八州)), plus Kai and Izu.[2] Later, Kantō Kubō Ashikaga Ujimitsu was given by the shogunate as a reward for his military support the two huge provinces of Mutsu and Dewa.[2]
