Ito Daisuke's wartime retelling of the Miyamoto Musashi story.

Shinobu and her brother Genichiro plead with famous swordsman Musashi Miyamoto to teach them to avenge their father's death. The perpetrators of their father's demise see the siblings practicing, and so enlist the help of another revered swordsman, Kojiro Sasaki, giving the latter an excuse to battle Miyamoto.

Second part of director Hiroshi Inagaki's 1940 adaptation of the story of Musashi Miyamoto.

Miyamoto Musashi is challenged by a series of opponents in this follow up to Miyamoto Musashi's Kongoin Ketto (1942, also called Nitoryu Kaigen) also directed by Ito Daisuke.
