Good martial arts, several of his students have taken in tournaments, full-contact in Denver, Japan, etc. He knows his karate, been teaching for years. He has a reputation for being strict, no-nonsense (traditional japanese style), and I sure as h'l would not go in and challenge him, unless you want to pick yourself up off the floor! Tradititional Japanese Kyokushinkai kata, blended with Okinawan stances and some techniques.
