Kobudo Renbukan is a traditional, non-profit martial arts organization based in Japan's ancient capital, Kamakura. Founded by David Kawazu-Barber, a long-term practitioner of ancient combative traditions, the organization is dedicated to the Research, Analysis and Practical Application of Classical Martial Art Systems. Our training adheres to the guiding principles of Taijutsu (a concept-based system of martial science developed by Japan's samurai warrior class), which emphasizes Simplicity, Practicality, Efficiency (in relation to time, motion and energy), Directness, Non-resistance, Reflex Responsiveness and Body Integration. Our training encompasses various forms of jujutsu, kenpo and weaponry, as handed down to us from ancient times. In addition to the physical aspects of our training, students are also versed in culture, history, tradition, strategy, etiquette and technical skills, such as the making of traditional weapons. Admission to the Kamakura dojo is via invitation only. If you have carefully read the membership guidelines and you feel that you could contribute positively to our community, please feel free to submit a written application.
Nihon Shurikenjutsu Hozonkai
The Japan Shurikenjutsu Preservation Society is actively involved in the research and training of traditional shurikenjutsu and associated arts. Founder, David Kawazu-Barber (Shihan) is a direct disciple of Saito Satoshi, headmaster of Negishi-ryu shurikenjutsu and Shirai-ryu shurikenjutsu, 2 of only 3 schools of classical shurikenjutsu to have survived antiquity (the third being Katori Shinto-ryu). Unlike other schools of shurikenjutsu which existed during the age of the samurai, Negishi-ryu was a specialist school focusing exclusively on blade throwing. In addition to its own unique methods of shuriken design and combat, the Negishi-ryu accumulated a wealth of knowledge from other schools of shurikenjutsu and assimilated them into its vast curriculum.
During the Edo period (1603-1868), the Tokugawa shogunate outlawed the practice of shurikenjutsu by anyone other than the Shogun and his family. But, despite this effort, the Edo era was in fact the heyday for shurikenjutsu, with many (martial art) schools adding it to their hiden (secret) teachings. These teachings were only made privy to the most senior initiates and were strictly passed on orally (kuden). In ancient scrolls we can find references to these teachings and in some instances, sketches of the shuriken used. But, the technical secrets were always passed on verbally from master to student, maintaining a high level of secrecy. For this reason, most of these ancient arts have now faded into the realm of antiquity. In the world today, there are only a few licensed teachers of authentic koryu shurikenjutsu. Of these few, most are now advanced in age.
Over the past 160 years, Negishi-ryu has only been passed on to a handful of select disciples. Current generation headmaster, Saito Satoshi (now retired) began his shuriken training 70 years ago under the tutelage of Naruse Kanji and from 1949 onward, Saito Satoshi became a friend and closed-door student of Fujita Seiko, last of the Koga ninja. During his lifetime, Saito sensei has only accepted a small number of disciples; David is privileged to be one of them. In 2010, Saito Satoshi, David Kawazu-Barber and Ueda Atsuko (granddaughter and last surviving member of the Fujita Seiko bloodline. She inherited Koga-ryu kenpo and Shingetsu-ryu shurikenjutsu from her mother and father, both licensed by Fujita Seiko) established the Shurikenjutsu Research Society in Tokyo, Japan. This exclusive society stills holds monthly meetings at Saito Satoshi's private training hall. The society is made up of Soke (headmasters) from various koryu (classical) martial arts. Our objective is to share and refine our skills and knowledge of authentic shurikenjutsu. David is registered with both the Japan Kobudo Association and the Japan Kobudo Promotion Society (Japan's oldest and most exclusive koryu community) and demonstrates the art of traditional shurikenjutsu at their official exhibitions throughout Japan. He currently serves as Regional Director for both Negishi-ryu and Shirai-ryu in Japan.Dojo Visits
Kobudo Renbukan is a small, non-profit organization with its main training hall (dojo) located in Kamakura, Japan. Our instructor works a regular full-time job, which in Japan, implies long hours. As such, the dojo presently operates only 1-2 days a week. It is not a full-time, commercial operation. Unfortunately, due to a lack of time and resources, we currently do not offer intensive training for overseas visitors (though we would like to). Dojo visits are by appointment only and are limited to potential students. We receive a lot of correspondence from curious people wishing to drop in for a peek. Please understand that we are operating a conservative dojo and not an amusement venue.
"Choosing not to pursue budo as a primary source of income, allows me to focus on what is important -- quality teaching.
Regardless of whether we have one student or a hundred, the training continues unhindered."
David Kawazu-Barber, Principal Instructor
