About Us

Okinawa Karate Center about us

For more than 45 years, Shihan Rusty McMains has been bringing the very best in martial arts instruction to the US and Canada. The Okinawa Karate Center UchinaaDiKan in Houston, Texas, has a long history of offering the most authentic Okinawa Goju-Ryu Karate-Jutsu,  Kobu-Jutsu and Martial Science instruction found in North America. In addition to teaching a very unique brand of Okinawa martial arts, all our teachings are based on sound medical and physical sciences as well as practical fighting and study methods developed by Shihan McMains through decades of real-time application. This places the Okinawa Karate Center UchinaaDiKan as one of the few schools in the world that expressly teaches these martial sciences as part of its general program, and one of but a handful in North America.

The Okinawa Karate Center UchinaaDiKan was born out of an overwhelming interest in the classical arts developed on Okinawa. The term "uchinaadikan" literally translates to "Okinawa (uchinaa) Martial Hand (di) Center (kan). A deeper translation, based on the extensive research by Kyoshi McMains and others, is more precisely interpreted as "The great center for the research and study of the indigenous life protection arts of the Okinawan people". Therefore, UchinaaDiKan was chosen to reflect the true nature of all Okinawan martial systems when self-preservation was a high priority, before these arts became a sport.

The Okinawa Karate Center UchinaaDiKan stands apart from most of today's franchised business based karate schools and systems in that our classes focus on the student as a person rather than as a client or customer.

Shihan McMains is not just a member of several of the world's leading martial arts organizations, he is a global leader in these fields. His highly expanded understanding of Western and Eastern sciences and his ability to apply those sciences to any form of martial arts training and protection techniques is unparalleled. He has consulted and trained instructors in Judo/Jujutsu, Arnis/Escrima, Karate, Taekwondo, MMA, Krav Magra and others.

A key to Shihan McMains' success in teaching his students is that he is himself an active student. In addition to his never-ending self practice and study in Okinawa Goju-Ryu and the Hokama Kobujutsu systems, Shihan McMains trains in Yamanni Chinen-Ryu Kobujutsu and is an active member of the Ryukyu Bujutsu Kenkyu Doyukai.

Just as impressive as Shihan McMains' personal experiences, is the collection of extensive experiences of associated schools and instructors both in North America and Okinawa that provide for a deep network of information and training unlike other organizations, all this with the intent in bringing our students the best instruction possible while leaving a legacy for future generations.

As a former amateur and semi-professional fighter, Shihan McMains understands what "putting it on the line" literally means. Though his students may never step into the ring, it is important that his students approach their training with this in mind.

Studying Under Masters

In the four plus decades Shihan McMains has been practicing the martial arts, he has had the distinct honor and privilege of training directly with some of the world's leading martial artists. Because of his close relationship with these instructors, some of the most prized classes were held in ordinary situations including hallways, poolside or on tennis courts of hotels, late nights in backyards, or restaurant parking lots while waiting for their table.

In addition to the hours of practice, there were hours of discussions on planes, in cars, hotel rooms and just hanging out at the house. With this privilege comes the responsibility of maintaining a very high level of knowledge, expertise, integrity, and trust.

What these masters passed to Shihan McMains was more than a martial art. They imparted the deep internal concepts and principles that supported their systems. The more they shared from their individual systems the more Shihan McMains began to see that they weren't all that different as these varied systems shared many of the same technical foundations. It was upon these "First Principles" that Shihan McMains developed his style of teaching.

The Okinawa Karate Center UchinaaDiKan, under the direction of Shihan McMains, is but one of a handful of dojos in North America and the only dojo west of the Mississippi River sanctioned and authorized to teach and represent this unique brand of Okinawan martial arts. The Okinawa Karate Center UchinaaDiKan has the privileged support of Hanshi Luis Morales, 10th Dan, Chief Instructor/Director KenShiKai NA.  Not only is Hanshi Morales the senior most student of Hanshi Tetsuhiro Hokama, 10th Dan, Founder and Head Instructor Kenshi-Kai International in the Western hemisphere, he was presented with the rare "Menkyo Kaiden" (License of Full Transmission) by Hanshi Hokama.

His doctors firmly believe that his physical condition and positive attitude developed over his lifetime of martial arts practice are just as much a part of his recovery as chemotherapy and other common cancer treatments.
