 Kamakura's ruler was called "Kantō kubō", a title equivalent to "shōgun" assumed by Ashikaga Takauji's son Motouji after his nomination to "Kantō kanrei", or deputy "shōgun", in 1349.Motouji transferred his original title to the Uesugi family, which had previously held the hereditary title of , and would thereafter provide the "Kantō kanrei".Motouji had been sent by his father because this last understood the importance of controlling the Kantō region and wanted to have an Ashikaga in power there, but the administration in Kamakura was from the beginning characterized by its rebelliousness, so the "shōgun"s idea never really worked and actually backfired.
