After the Heiji War in 1159, reportedly, Koremichi watched FUJIWARA no Nobuyori make awards at his own sweet will and treat samurai (warriors) favorably, saying 'If those who killed many persons get prizes, why no official rank is given to the well in Sanjo-dono,' and thus severely criticized Nobuyori who was the leader of the War (His words were to ridicule the fact that many court ladies killed themselves by jumping into the well when Nobuyori-side's army surrounded the Sanjo-dono).
平治元年（1159年）の平治の乱の際には、藤原信頼が勝手に行った論功行賞で武士を厚遇するのを見て、「人を多く殺した者が恩賞に与るのであれば、どうして三条殿の井戸に官位が与えられないのか」と発言、乱の首謀者である信頼を痛烈に皮肉ったと伝えられる（信頼方の軍勢が三条殿を焼き討ちした際に、多くの女官らが井戸に飛び込んで死亡したことを揶揄したもの）。
