Watch Blind Monk Swordsman (1964) Official Trailer

This is the story of a bad man who re-discovering humanity via woman and child while clashing with the yakuza and being hunted by a man called “Death” who has his own dark past. The prototype for the later two yakuza priest series with Shintaro Katsu and Tomisaburo Wakayama. Apparently so. And the swordsman motif seems to have been concurrent with Daiei's first ZATOICHI production.
