Seven Samurai Kyuzo master swordsman

This is a difficult question. The actor Seiji Miyaguchi had no background in sword practice. Director Kurosawa brought two sword masters onto the set to teach the actor basic sword technique. One left because he had other opportunities. One remained and taught Miyaguchi. Does anyone know this sword master’s name? There used to be a video on You Tube showing this man demonstrating sword technique at the age of 90 but I cannot find it anymore. Thanks for any help!

Hi mandeldog! Yoshio Sugino was the swordplay instructor for Seven Samurai. Might this or this be the video that you were looking for?

Thank you, Vili! It takes a true lover of the Seven Samurai to know that!
