Mr. Raul Andaya has arrived safely in Japan. 🇯🇵Before the JKA Spring Camp begins, he took the opportunity to train at Naka Sensei’s dojo for some extra training.

This is what JKA Arizona is all about — dedication, initiative, and continuing to train at the highest level. Proud to see our dojo represented in Japan.

Way to go, Raul!

OSSU! 👊, Chuck Coburn www.KarateAZ.com

Did you get your day started right — a short walk, some stretching, and 15 minutes of light karate practice… maybe a couple of kata? A great way to begin the day.
Cheers, y’all — Chuck Coburn, OSSU! 😉

Special moments like these remind us what karate is truly about. 🥋

Having a team member visit us all the way from Japan made this time even more meaningful, and at the same time celebrating one of our young karate girls as she prepares for college—proud moment for all of us!

Karate connects us across the world and through every stage of life. Grateful for our dojo family and the memories we continue to build together!

OSSU! 👊🏻

Hong Kong, 1985 🇭🇰

A special moment with Yaguchi Sensei and teammates. Left to right — Our Sensei Chuck Coburn on the end next to Yaguchi Sensei: Stuart Smith, Dan Wolf, Asa Herring.

Training and competing with Yaguchi Sensei was all business — focused, disciplined, and intense. But outside of that, he was truly amazing to be around. Our Sensei Chuck shared many laughs and unforgettable moments.

Thank you, Sensei, for sharing this amazing photograph from the 1980s. 🙏

Moments like these are truly priceless—full of history, dedication, and spirit. Grateful to be part of such a legacy.

OSS!
