Karate-dō Dojo history

Arizona JKA carries on the legacy and training of Master Koyama
Arizona Japan Karate Association may only be a few years old (we were founded in 2017), but we build on the legacy of the Arizona Karate Association. When Master Shojiro Koyama retired in 2017, he requested that we continue teaching the art of Shotokan Karate. We created Arizona JKA as a non-profit to carry on the legacy and training of Master Koyama.
But the history of the dojo actually begins in 1961, when Gary and Joan Abbott started the dojo in a building at 28th street and Thomas. The dojo members trained here, and went to Los Angeles to train with Master Nishyama who was at that time the Japan Karate Association’s closest teacher to Phoenix. Joan and Gary requested a Japanese instructor for the Phoenix dojo, and the JKA sent Shojiro Koyama to Phoenix in 1964. Gary and Joan’s legacy continues, as their daughter Kimi is on the AJKA board, and teaches and trains at the dojo.
Sensei Koyama taught thousands of students during his years as a karate sensei. He taught at Arizona State University, Phoenix College, Mesa, and of course at the dojo. The dojo moved to its current location in 1969. In [year] the dojo joined the ISKF (International Shotokan Karate Federation), which was led by Master Okazaki. While part of the ISKF, Master Koyama began what would become the longest-running karate tournament in the US, the Western States Karate Tournament. Western States was a non-profit that benefitted local organizations (The 100 Club of Arizona) and national organizations (Cystic Fibrosis Foundation) during its 51-year history.
Sensei Koyama also established the Western Region Summer Camp, which ran for 35 years, most of those in Flagstaff, and the last 13 years in Payson, Arizona. Thousands of students benefited from the advanced training in both locations.
The Dojo has always been a place for both old and new friendships, attracting a diverse group of people interested in a common pursuit. This natural diversity allows people to focus on what we have in common, rather than how we are different. In addition, it creates a positive model for our increasingly polarized society.

In this blend of old and new, the ultimate goal continues to be the physical, mental, and spiritual benefits of traditional martial arts training for children, adults, and seniors. The tradition continues at the Arizona JKA, with respect for the past and excitement for the future. Our children, through hard work and effort, absorb the energy and culture of a traditional Dojo. Just as Master Koyama came to the United States to spread traditional Shotokan Karate, we look to our youth to carry on that tradition for future generations.
