Where to Watch Ken (1964)

Kokubu, captain of his university's kendo team, is a mystery to those who know him: An ascetic dedicated to a point of obsession with the simplicity and beauty of the sword arts. Kagawa, a promising but arrogant kendo student, is attracted to Kokubu's devout leadership but kept at a distance by his standoffish nature. With the national championships fast approaching, the pair clash as Kokubu drives his students with increasingly rigorous training and Kagawa tests Kokubu's grip on the class.
