According to the description of "Gyokuyo," the record of the day, from the late December to early January, the Omi-Genji (Minamoto clan) including Yoshitsune YAMAMOTO was in the middle of the battle against the tsuitoshi, so some say that the articles in "Azuma Kagami" on the fall of the castle on December 4 and the meeting with Yoritomo on January 4 are not trustworthy.
当時の記録である『玉葉』の記載をおくならば12月上旬は山本義経他の近江源氏は平氏の追討使と交戦中であり、『吾妻鏡』の12月1日の落城ならびに12月10日条の頼朝の対面という記事は信用がおけないという説もある。
