Samurai Kamakura Gongorō Kagemasa, the hero of the Kabuki theatre play Shibaraku.

The historical Kamakura Kagemasa is famous for his bravery for having continued to fight for the Minamoto clan after losing an eye in battle in the Gosannen W ar (1083–1087). In the play, when the evil lord has ordered his retainers to kill the imperial prisoners who will not obey his will, Kamakura Gongoro, who is capable of superhuman strength, appears with the shout “Shibaraku” (Wait a Moment!) and saves their lives.
