Self-Defense (Goshinjitsu)


A comprehensive self-defense system that incorporates a wide range of skills including striking, throwing (judo), grappling and submissions. While its curriculum is based on classical jujitsu, the techniques themselves have been refined and modernized. The friendly tone of the style and its course structure emphasize the virtues of honor humility and respect.


Matsuno Ryu Goshinjitsu was founded by Joseph Holck, Dai-Shihan, Kodenkan Yudanshakai, whose original name prior to WWll was Joichi Matsuno. Dai-Shihan Holck studied Danzan Ryu Jujitsu and Judo directly under Professor Seishiro Okazaki, founder of the Kodenkan in Hawaii. He also served in the armed forces and was one of the original five founders of Kajukenbo, which at that time was one of the first “mixed martial arts” to be modernized. In 1967 he founded the Kodenkan Yudanshakai in Tucson, AZ and later taught his sons the principles that would become Matsuno Ryu Goshinjitsu. They then began to teach these arts to the general public.


In 1984 Shihan John McGraugh, founder of the Southern Arizona Kodenkan, began studying Goshinjitsu under Vinson Holck, Shihan, son of Joseph Holck, Dai-Shihan. Learning that Matsuno Ryu Goshinjitsu is an art designed to continue improving and changing Shihan McGraugh now teaches a more modernized version of this art incorporating techniques acquired from his studies in Japan, from the mixed martial arts and from various other sources.
