Arizona JKA: Shotokan Karate-Do

Arizona Japan Karate Associations

Continuing the Tradition

Arizona JKA is a non-profit, 501(c)3 organization established to carry on the legacy of Master Shojiro Koyama, and is the continuation of Arizona Karate Association. We are JKA-qualified instructors teaching all levels of Shotokan Karate-Do.

Why a Non-Profit?

Lifetime Exercise

We train in karate as lifetime exercise. We have members as young as 5 and as old as 80. Martial Arts training helps in all aspects of life, increasing overall health and well-being, stress reduction, and increased focus.

Educational Karate-Do

Karate-do is physical, mental, and spiritual. In addition to practicing kihon (basics), kata (forms), and kumite (sparring), we learn about the philosophy and Japanese culture.

“Koyama sensei and his many dedicated and proficient students are legends both in the US and abroad. I've been training for 16 years and have been looking forward to training at this dojo for a long time. My first few classes have been great. The class is full of people showing good spirit, and the instruction is also very individualized. A warm atmosphere and top-notch instruction, what more could you ask for?”

“My husband & I trained here for 35 years. This is a family dojo as our children & grandchildren have trained as well. The best part was training in the family class with our grandchildren.”

"This is a perfect place to train karate in the most fulfilling way of the martial art. There are many experienced black belts that have learned this noble martial art from our legendary karate master Koyama Sensei who is very close to the root of the real karate shotokan! The Sensei and the Senpais are very helpful and wise. There is a family atmosphere on the place that make us feel home. Respect and learning are priorities on this dojo. I feel very fortunate to have found this wonderful place. A real dojo with a real Karate that will change your life completely!"

If you're looking for a real traditional JKA (Japan Karate Association) system of shotokan karate school in the Phoenix area, THIS IS THE PLACE. The school is registered under JKA/WF (World Federation) America and also with JKA Headquarter in Japan. This organization is the successor of Arizona Karate Association. Shojiro Koyama Sensei is the Chief Instructor. Under his tutelage are dedicated and highly qualified JKA instructors. This is not a JKA wanna-be school but the REAL DEAL. The instructions in the class are based on the latest JKA teaching methodologies. The teachings are very technical in nature and helps you understand the reasons behind every kihon (basic karate techniques), kata (karate form or structured karate techniques and movement) and kumite (sparring) that you'll learn. The classes are enjoyable too, but making sure everyone learn and develop one's self seriously. It might be daunting at the start, but your hard work will pay off. As Koyama Sensei always say, "No pain no gain". If you're serious in learning the JKA system of shotokan karate, develop positive attitude and self-confidence, as well enjoy the camaraderie of its members, THIS IS THE PLACE. Come on and join and see it for yourself.”

“It’s hardly been 1 year and Jane has learned so much. Having just earned her third belt, the color green is somehow now her new favorite color. Jane’s family and friends have all commented on how she’s more confident, super toned and beams with pride when asked about her training.
The instructors each bring something special and her fellow students are kind and supportive.
Jane looks forward to going to the dojo 3 times a week, anything a 17 year old does without being asked, especially karate is worth its weight in gold. ”
