Early life
Shintarô Katsu entered the world on November 29, 1931 in Tokyo, Japan, the son of Kineya Katsutōji, a shamisen player who ran a music school. As a child, Katsu had a blind shamisen instructor, a coincidence that later informed his portrayal of the blind Zatoichi. His younger brother, Tomisaburō Wakayama, also became a celebrated actor.
