Jōkyū War
Even in Satsuma Province, the Shimazu clan's rule was not stable. As a result of the Jōkyū War, Satsuma's Kawanabe District came under the control of the Tokusō (mainline) family of the Hōjō clan. Hōjō's retainer, the Chikama clan, served as the district governor and deputy jitō of Kawanabe District.
