Imperial Princess Sakahito (the daughter of Imperial Princess Inoe) was suddenly appointed to Ise no Saio (Saio of the Ise-jingu Shrine) at the age of 19 on December 15, 772, after the deposition of her mother Imperial Princess Inoe as empress and Imperial Prince Osabe as crown prince, a daughter of Imperial Princess Inoe, and there is a possibility that the incident was related to the appointment of Imperial Princess Sakahito to Saio.
さらに、宝亀3年（772年）、母の井上内親王と他戸親王の廃后と廃太子事件のあった後の11月13日(旧暦)、俄かに井上内親王の娘の酒人内親王が19歳で伊勢の斎王にト定されており、この事件と酒人内親王の斎王ト定は連動していた可能性がある。
