Join the Rengokai!



We are not interested in politics and do not interfere or dictate in the way that members run their organization or any other affiliation which they may be involved with. When requested, we endeavor to assist members in any way possible through our global information network.

We warmly invite you to join our organization!

Organizational Affiliation fee is $250 LIFETIME.


For affiliation, please send us an email with the personal résumé, photo and copy of the graduation diploma of the School Owner/Head Instructor. Send it to Association Headquarters. Notification will be sent as soon as the applicant has been approved, and, all of the requirements for joining are satisfied. The next step in the process is to organize a training session with Headquarters. This is usually accomplished through a Seminar involving the student body and Instructors. This approach allows you to monitor their reactions to the new training. For a Dojo to maintain its Affiliation in the event its Head Instructor is incapacitated or leaves the Dojo, the next senior student must be, or obtain, Individual Membership in the Rengokai.

Individual Membership

Individual Membership with the Rengokai can only be obtained through an affiliated school or Black Belt member. Talk to your instructor. If your school is affiliated with us, ask to become an Individual Member. If Your school isn't affiliated with us, ask your instructor to visit our website!

In order to protect the integrity of the Rengokai, all organizations and unaffiliated Black Belts must be vetted, personally, before they can be admitted to membership. Member organizations can attend and/or organize seminars of the Ryukyu Kenpo Karate Kobudo Rengokai when they want and where they want. This is a SERVICE organization FOR its MEMBERS.

The Ryukyu Kenpo Karate Kobudo Rengokai accepts, but does not certify nor issue certificates for, the rank currently held by members joining the Rengokai that was issued by other organizations. In addition, we leave all Kyu (colored belt) level certification in the hands of the individual Dojo and Organizations. The RKKKR does accept applications for Teacher and Dan level certification from Individual Members, authorized by their organization, who wish to verify their current, or progress to another, level.

If you feel your organization can pass muster, and, could benefit from an Association that cares more about its members' well-being than their money, then, contact us about joining an elite group of dedicated professionals who care about quality of the arts they learn and teach.



Being as how we are members of a global organization, Seminars are a necessity in our training regimen. They, like our training, are at the same time painful and joyous occasions. The good, most times, far outweighs the bad involved with Seminars. Shuseki Shihan J.D. Natan, (納騰 徳維,首席 師範) teaches seminars. If you would like to host a seminar, even in the USA, weapons, self-defense, or other, please contact us via the 'Contact' page. Any proposals for seminars, trips or events, with Sensei J.D. Natan, will be finalized with prepaid round trip travel arrangements and half of the agreed upon fees. Due to Sensei Natan's age and health, he now requires Sensei Yehoshua Kadosh to accompany him in order to assist him in teaching and traveling. Daishihan Kadosh's travel expenses are to be met in full.

When Natan, Sensei teaches, he is sure to explain the small details that are often left out of the instruction of many others. He makes sure that he has a couple of days, before and after, any seminars, or camps, he teaches, to spend additional time with the host instructor, to insure that he is "ahead of the curve", and capable of assisting his students to apply and remember the material that was covered in the training sessions. This total commitment, to the quality of the instruction, is what is missing most of the time. This is why so many are so impressed by his knowledge and approachability.
