Chinzei bugyō and Mutō

The Chinzei bugyō is the office Kamakura set up in the 1190s to hold the housemen of Kyūshū together, work the old Dazaifu machinery and watch the sea.

Its first holder was Amano Tōkage, who is remembered for his campaigns in the south in the 1180s; by the late 1190s Mutō Sukeyori, a clerk-warrior of Fujiwara claim, is at Dazaifu in his place or beside him, and his house will take the title Shōni (the Dazaifu's second-in-rank) as its name. The commission sits in the same compound as the court's own Dazaifu offices; the court's governor-general (daini or gon-no-sotsu) is an absentee courtier. The result is a double government of the north of the island, on which the Ōtomo, the Shimazu and the great shrines all lean.
