Only the descendants of Fujiwara no Kamatari's eldest son Fuhito were allowed the name of Fujiwara. All the other members of the Nakatomi clan kept their original family name until Nakatomi no Imimaro was promoted to "chūnagon" with the support of Fuhito. In 764, Kiyomaro, the son of Imimaro, sided with Emperor Kōgen during the Fujiwara no Nakamaro Rebellion, and in 769, he was granted the name Ōnakatomi, thus establishing the Ōnakatomi clan. In the Heian period, all three legitimate houses of Nakatomi clan were granted the name Ōnakatomi. Nakatomi no Ichishi was the last "jingihaku" (Head of the Department of Worship) of the Nakatomi clan, and his son Itohito later took the name of Ōnakatomi, thus being the last member of the Nakatomi clan.
