Sensei Miyoshi (Michael) Shiwara was Head Instructor of Karate Do Shotokai, at the Sommerville Dojo.  In this picture, Sensei is off to the right while Gagnon, then a student at MIT took this picture of a practice.  The Shodan in the foreground is Rick Bolger, a friend and fellow student at MIT.  Notice the deep Zenkutsu Dachi (forward leaning stance) which is a hallmark of the Japanese karates.
