There are some records in Kyoto, including "Meigetsuki" (Chronicle of the Bright Moon) by FUJIWARA no Teika, that describe the report, 'Since Yoriie died of disease on October 14, Sanetomo succeeded the position of Shogun,' that was delivered in the early morning of October 20th and an appointment of Sanetomo to Seii Taishogun was requested even though Yoriie was still alive.
まだ頼家が存命しているにも関わらず、鎌倉から「9月1日に頼家が病死したので、実朝が後を継いだ」との報告が9月7日早朝に都に届き、実朝の征夷大将軍任命が要請された事が、藤原定家の日記『明月記』の他、複数の京都側の記録で確認されている。
