Absolutely wanted to share this video of a self-defense demonstration by Sensei Kanazawa. Of course, this is only a demonstration of Shotokan Karate, and therefore choreographed. But, yes, the moves are genuine and it gives you an insight into the spirit and control of martial arts.
I love this video and how it showcases Kanazawa’s form and control. The self-defense move at the 1:00 minute mark is stunning. Enjoy!
