HOSOI thinks that the demotion of Dokyo is a typical political change of the time and that the reason Kiyomaro did not receive an important position in the court of Emperor Konin was that originally he came from a powerful local clan and he was a member of close advisers to Emperor Shotoku and his connection with the side of Emperor Konin was not so close.
道鏡の左遷はこの時代の典型的な政変であり、清麻呂が光仁朝で重用されなかったのは、彼が元々地方豪族出身でなおかつ称徳天皇の側近層であった以上、光仁天皇側とのつながりは希薄だったと解している。
