While Yasutada was sick in bed, he chanted a sutra of Yakushi Nyorai (the Healing Buddha) as a prayer, as soon as he heard the name of konpira (guardian deity of seafaring), he went mad (it is said that he, Konoe no daisho (Major Captain of the Palace Guards), thought to be killed) and died a short time later ("Okagami" (the Great Mirror)).
保忠が病床に伏せ、祈祷のため僧侶に薬師如来の読経をさせた途中、金毘羅の名前が出た事を聞いた途端に発狂し（近衛大将である自分を縊るのだと思ったという）、まもなく絶命した（『大鏡』）。
