Following the Genpei War, Yoshitsune was appointed as Governor of
Iyo and awarded other titles by cloistered emperor
Go-Shirakawa. His suspicious brother Yoritomo, however, opposed the presentation of these titles, and nullified them. depicting Yoshitsune and his retainers looking at the rough sea while fleeing from Yoritomo's pursuers, by Ishikawa Komei, circa 1880.

Minamoto no Yukiie in opposing Yoritomo. Incurring Yoritomo's wrath, Yoshitsune fled Kyoto in 1185. His faithful mistress,
Shizuka Gozen, carrying his unborn child, fled with him at first, but then was left behind, and soon taken into custody by forces loyal to Yoritomo. Yoshitsune eventually made his way to Hiraizumi, Mutsu, once again to the protection of Fujiwara no Hidehira, and lived undisturbed for a time. Hidehira's son
Fujiwara no Yasuhira had promised upon Hidehira's death to honor his father's wishes and continue to shelter Yoshitsune, but, giving in to pressure from Yoritomo, betrayed Yoshitsune, surrounding his Koromogawa-no-tachi residence with his troops, defeating Yoshitsune's retainers, including
Benkei (in a famous
"standing death"), and forcing Yoshitsune to commit
seppuku. Yasuhira then had Yoshitsune's head preserved in sake, placed in a black-lacquered chest, and sent to Yoritomo as proof of his death. Historical sources differ as to the fate of Yoshitsune's mistress Shizuka and their son. Yoshitsune is enshrined in the
Shirahata Jinja, a
Shinto shrine in the city of
Fujisawa. == Rumors and legend ==
