清和天皇
Yoritomo was the third son of Minamoto no Yoshitomo, heir of the Minamoto (Seiwa Genji) clan, and his official wife, Yura-Gozen, daughter of Fujiwara no Suenori, head of Atsuta Shrine and a member of the illustrious Fujiwara clan. Yoritomo was born in the family villa, on the western side of Atsuta Shrine, in Atsuta, Nagoya, Owari Province (present-day Seigan-ji). At that time Yoritomo's grandfather Minamoto no Tameyoshi was the head of the Minamoto. Like Benkei, his childhood name was Oniwakamaru (鬼武丸). He was a descendant of Emperor Seiwa.
