About "Okinawa-Kenpo" ――

Okinawa-kenpo is a karate style which has been developed based on ancient Okinawan martial arts called "Ti". Its technique and thought were studied and refined by a Tomari-te master, Shinkichi Kuniyoshi (also known as "BUSHI" Kuniyoshi) and passed down to Grand Master Shigeru Nakamura, the founder of Okinawa-kenpo. Grand Master Nakamura opened his own dojo "Okinawa-kenpo Karate-do Shurenjo" at Onaka, Nago city and taught his art of karate.

Okinawa-kenpo is a karate style which has been developed based on ancient Okinawan martial arts called "Ti". Its technique and thought were studied and refined by a Tomari-te master, Shinkichi Kuniyoshi (also known as "BUSHI" Kuniyoshi) and passed down to Grand Master Shigeru Nakamura, the founder of Okinawa-kenpo. Grand Master Nakamura opened his own dojo "Okinawa-kenpo Karate-do Shurenjo" at Onaka, Nago city and taught his art of karate.

Grand Master Nakamura disliked the thought of karate being divided into separate styles. There used to be no Ryuha (schools) in Okinawa karate. All styles were merely called "Ti". That was the reason why he simply named his karate "Okinawa-kenpo", which means "Okinawa Ti". His intension was to unify all styles of karate under the name of Okinawa-kenpo. He called for like-minded karate-ka (karate practitioners) and held meetings to try to make his dream come true.

In June 17, 1961, karate masters from all over Okinawa gathered at Yashio-so, Naha city. At this meeting, they had a discussion about the unification of Okinawa karate and finally came to endorse it (Establishing of Okinawa Kobudo Kyokai). However, after Grand Master Nakamura's passing in 1969, the group fell apart.

Today, Okinawa-kenpo is known as a name of karate style. We use the term of "Okinawa-kenpo" not only for indicating our style, but also for inheriting Kuniyoshi and Nakamura's will. Our goal is to preserve BUSHI Kuniyoshi's Tomari-te and pass it to the next generation.

"Until the formation of Okinawa-kenpo"

"Okinawa-kenpo" was founded by Grand Master Shigeru Nakamura in 1960 as an association of diverse dojos based on his belief "there is no Ryuha in Okinawa karate".

Participation to a competition in Kyushu as "The All Japan karate-do Federation, Okinawa District" was how it all started. Nakamura felt how strong Japanese karate organization was at the competition and worried about the future of Okinawa karate.

Then, he appealed to all karate-ka in Okinawa for participating to the movement of "Okinawa-kenpo".

In June 17, 1961, karate masters from all over Okinawa gathered at Yashio-so, Naha city. At this meeting, they had a discussion about the unification of Okinawa karate and finally came to endorse it (Establishing of Okinawa Kobudo Kyokai).

After Nakamura's passing, the group fell apart. However, Okinawa karate advanced to an era of great development.

Each karate style goes on its own way, and Okinawa-kenpo has become the name of the style which was taught and practiced by the students of Grand Master Nakamura.

Various Ryuha participated in the movement of "Okinawa-kenpo".

Mostly, they were from "The All Japan karate-do Federation, Okinawa District" and "Okinawa Kobudo Kyokai". Exchange of techniques was widely performed among them.

"After the passing of Grand Master Shigeru Nakamura"

After the death of Nakamura, Okinawa-kenpo was divided into several groups.
Each group inherited Nakamura's will and techniques and developed Okinawa-kenpo in their own way.
