Even though it is conceded that this 'diary' is the same as the tales of "Hogen" and "Heiji," Enkeibon, which preserves the original form of "Heike Monogatari" but doesn't contain the same words, it is questioned whether it really tells the truth about the period when Kiyomori was alive.
仮にこの「日記」を『保元』『平治』の物語とおなじと認めた場合でも、『平家物語』の古態本である延慶(日本)本などにはこの話はなく、本当に清盛生存時の事実を伝えているかどうかはかなり疑問もある。
