Fuhito was 13 years old when the Jinshin incident occurred.
His father Kamatari had been a strong supporter of Emperor Tenji, but Kamatari had already died and Fuhito was too young to be appointed a governmental officer, so he was not involved in this political conflict. In 688 he appeared first as a courtier.
In 697 Prince Karu, the son of Prince Kusakabe and therefore grandson of Emperor Temmu and Empress Jitō, was appointed crown prince. Fuhito supported this appointment strongly and gained the favor of Empress Jitō.
