壇の浦夜枕合戦記 (1977)

Taken out of the pages of history itself, this is the story of the sizzling love between Kenreimon-in of the Taira Clan and Yoshitsuné of the Minamoto Clan. When the Taira Clan had met ignominious defeat at the hands of Yoshitsuné, Kenreimon-in had jumped into the sea with her son, the infant Emperor, but only she had been rescued by Yoshitsuné. A rough-hewn warrior, Yoshitsuné had taken her by force until he awakened an answering love in the Empress with his chamber techniques.
