Kanketsu Sasaki Kojirô: Ganryû-jima kettô (1951)

Master swordsman Kojiro Sasaki is not content with the knowledge of his own power and constantly seeks to impress it upon others. Another great samurai swordsman, Musashi Miyamoto, has great respect for Sasaki's skills, but seeks to find spirituality and redemption for past sins rather than glory. Sasaki challenges Miyamoto, who tries to avoid conflict, but eventually the two must meet. They do so on Ganryu Island.
