In response to this request, the retired Emperor Gotoba sent his vassal Tadatsuna Fujiwara to Kamakura, who submitted as requirements that the punishment of the gokenin (low-ranking warrior vassal) Morita NISHINA (a member of the Western Guard Corps), who was close to the retired Emperor, be overturned, and the annulment of responsibility over the Nagae estate in Settsu Province, which belonged to the courtesan Igakyoku (formerly the prostitute Kamegiku), and the Kurahashi estate be repealed.
これに対し、後鳥羽上皇は近臣藤原忠綱を鎌倉に送り、愛妾伊賀局（元は遊女の亀菊）の所領である摂津国長江荘、倉橋荘の地頭職の撤廃と院に近い御家人仁科盛遠（西面の武士）への処分の撤回を条件として提示した。
