Watanabe sensei was very welcoming and open, a trait shared amongst all the best karateka I've had the pleasure to meet. Although he is a dedicated and serious Kudo sensei, he also trains karate kata on his own, bringing back one traditional aspect of karate that is lacking in Kudo. Under the name
Yuiga-ryu, He has done some deep introspection and personal reflection of kata and bunkai, and shared some interesting insights with me after the Kudo class had ended. Interestingly, although the Kyokushin katas take after Naha-te styles like Goju-ryu, Watanabe sensei is really fascinated by Naihanchi, the foundational kata of Shorin-ryu, and has published an entire video series about it. He made me think of Choki Motobu, an experienced fighter who went his own way, establishing Motobu-ryu, and spent much of his life plumbing the depths of Naihanchi.
