Career
During the Genpei War, he controlled his territory independently of the central government. However, he was the official imperial governor for Mutsu Province as of 1181. He offered shelter to the young Minamoto no Yoshitsune, who had escaped from Kyoto.
Yoshitsune was still Hidehira"s guest when the latter died in 1187.
Yasuhira then had Yoshitsune"s head preserved in a jar of sake and sent to Yoritomo. This did nothing to appease him, and Yoritomo destroyed the Fujiwara domain and killed Yasuhira, son of Hidehira in 1189.
Hidehira"s corpse became a mummy, preserved today within the Konjiki-dō of Chūson-ji. According to legend Hidehira was raised by wolves.
