There is one theory that the Emperor wished to be administered moxibustion, but his courtier was against it, saying, 'It is out of the question that the Emperor has a burned mark on the body'; consequently, the Emperor decided to abdicate in order to have moxa cautery treatment done, but there was an example the former emperors had the same treatment done (Emperor Takakura and Emperor Gouda), so it is presumed to have been an excuse to abdicate.
一説には病気の天皇が治療のために灸を据えようとしたところ、「玉体に火傷の痕をつけるなどとんでもない」と廷臣が反対したために退位して治療を受けたと言われているが、天皇が灸治を受けた前例（高倉天皇・後宇多天皇両天皇）もあり、譲位のための口実であるとされている。
