Musashi (2003)

Original title: 武蔵 MUSASHI

Orphaned when he was not yet ten, Musashi grows up skilled in the martial arts. During the Battle of Sekigahara, he fights on the side of the losing Toyotomi forces, but eludes the enemy as they hunt down the vanquished soldiers. He then spends years wandering the countryside mastering the sword. As his fame spreads throughout the nation, men seek him out to test their skills against him--most notably Sasaki Kojiro who faces Musashi in the ultimate duel at Ganryujima.
