Sadly Kanazawa shihan passed away on the 8th of December peacefully in Japan. If you practice karate at all for any decent length of time (more than a year)the chances are you will have used one of his youtube vids. As a Grandmaster winning both Kata and Kumite titles in 1958 he won the kumite in 1957 everyone I know checked their kata against his.
I personally never had the pleasure of training or meeting him but everyone who did spoke highly of him as a person and as a shotokan master. Gibshot send our condolences to his family and to the wider family of karateka who feel the loss to our art.
