Knowing that the end of his life was approaching, Kiyomori reported to the Cloistered Emperor that Munemori would take over whatever was left after his death and therefore requested him to cooperate with Munemori to carry out political affairs, but since there was no reply from the Cloistered Emperor, Kiyomori held a grudge and left word to 'leave all the state affairs to Munemori and never disagree with him,' and finally died in the residence of TAIRA no Morikuni in Kujo-kawaraguchi on February 4 (leap day).
死期を悟った清盛は、自分の死後はすべて宗盛に任せてあるので、宗盛と協力して政務を行うよう法皇に奏上したが、返答がなかったため、恨みを残して「天下の事は宗盛に任せ、異論あるべからず」と言い残し、閏2月4日に九条河原口の平盛国の屋敷で死去した。
