About Full Contact Ryukyu Kenpo


Ryukyu Kenpo Kobujutsu (琉球 拳法 古武術) along with Bogu Kumite (full contact sparring) is one of the oldest, and most effective, life protection arts that man has ever developed. Through centuries of development in the orient, bodily movement, physical blows, punches, and kicks have been refined to a level never before seen in human history. The training is difficult and demanding. It takes perseverance, high motivation, a good mind, and, an unwillingness to compromise standards. Self-defense is not a game. Our goal is to provide effective strategies and skills for surviving violent encounters – at whatever level. As much as we endevour to instruct you in successfully developing your mind and body, it is imperative that you practice rigorously and properly, as instructed.

The Self Confidence created by Ryukyu Kenpo Kobujutsu training with Bogu Kumite, also gives one the courage to set and work towards worthy personal goals; as well as living free from fear. The Kenpo movements and exercises help decrease built up stress and tensions in the body and mind; leading to greater health and self improvement, while enhancing the length and quality of life enjoyed by Ryukyu Kenpo practitioners.

Ryukyu Kenpo is taught by Certified Licensed instructors. These credentials are prominently displayed, or available on request, by all legitimate instructors. Ryukyu Kenpo is a vast and complicated subject involving striking with both arms and legs, parries, entrapments, immobilization's, balance interrupts, joint locks and dislocations, anatomical physiological point structures, analytical research, Kata, weapons (improvised as well as standard weapons), two man drills, contact sparring, character development, mental development techniques, and a deep and abiding respect for man and our world. Even something as simple as punching someone entails such minutiae as: distancing, timing, angle of attack, twist, load bearing surfaces, point physiology, and energy release (Ki) and transference.

Today, unfortunately many people think Ryukyu Kenpo Kobujutsu is some type of "Karate". Through misinformation, due to ignorance of history or fabrication by unscrupulous agenda driven instructors, they do not realize that Karate and its offshoots like Taekwondo and many others are weak, watered down, often sporterized, derivatives of the original Ryukyu (Okinawan) Kenpo and Kobujutsu. The father of Karate in Japan, Gichen Funakoshi's, first book written for the Japanese was "Ryukyu Kenpo Karate-do" in 1922. In his final book, written just before his death in 1957, he reaffirms that "Karate" came from Ryukyu Kenpo; and discusses how he changed it, and other names to better suit his Japanese students. Choki Motobu, another Okinawan instructor (and renown fighter) was Funakoshi's nemesis. His book "Okinawa Kenpo Karate-Jutsu on Kumite" was published in Japan in 1926. Motobu concentrated on Kumite (fighting techniques) and not just on Kata as did Funakoshi. These two men and their students were the main forces behind "Karate" in Japan; and by extension the world. They both were Kenpo instructors from Okinawa; the main island in the Ryukyu chain.

Yehoshua Kadosh is the head instructor of the Kenpukan dojo in Jerusalem, Israel. In 2001 Yehoshua began training in Ryukyu Kenpo with Grand Master D'veed Natan. As he quickly rose in rank he began to teach children as an assistant instructor to Hanshi D'veed Natan at the Academy of Ryukyu Kenpo in Jerusalem. In 2004 Yehoshua was instituted as Director of the Children's Training Department for the Ryukyu Kenpo Kobujutsu Kai. Also, having been a skilled sparring student he was given the responsibility of teaching sparring classes for adults at the Ryukenkan dojo in Jerusalem. Since 2008 Sensei Kadosh has run his own classes in Ryukyu Kenpo, Bogu Kumite and Kobujutsu at various locations in Israel, On the 16th of May, 2013, Yehoshua Kadosh received his 5th Dan rank, full teaching license as well as the title of "Renshi" from 10th Dan Grand Master D'veed Natan. In 2015 Renshi Kadosh was promoted to Director of Research and Development of the "Ryukyu Kenpo Karate Kobudo Reengokai".

Renshi Kadosh is a graduate of the "Wingate" program at Tel Aviv University, studied "kappo" (resuscitation techniques), and trained in first aid with Magen David Adom professionals. Teaching has become a specialty with Renshi Kadosh not only because of the patience and care that he shows to his students, but also because of his methodical approach to teaching and attention to detail that ensures complete understanding of the material demonstrated.
