Bruce Juchnik is a 10th degree black belt and the Grandmaster and Hanshi of Kosho Shorei-Ryu Kempo, teaching from his school in Orangevale, California. Mr. Juchnik began his training in the Tracy System of Kenpo, obtaining a 3rd degree black belt, and operating a successful chain of self defense studios. While it was known that James Mitose was responsible for bringing the art of kenpo to America, no one had heard of this man since he retired from teaching in 1953. Juchnik came into contact with Mitose and the kenpo art of Kosho Ryu while working as a prison guard between 1977 to 1981, at Folsom Prison. One of the inmates at the prison turned out to be The Honorable Professor James Mitose, the 21st Great Grandmaster of Kosho Ryu (21 generations removed from Bodhidharma) and patriarch of the Temple in Kyoto, Japan.

Mr. Juchnik, Rick Alemany, Ray Arquilla, Eugene Sedeno, and Arnold Golub spent many hours with Mitose discussing their respective kenpo arts. It was during these times that Mitose revealed the philosophical aspects of the Kosho system. These men all had a good, solid background in the physical art of kenpo, but Mitose sought to complete their training by revealing the other aspects of the art to them.

Most kenpo systems are based on the War Arts, which are techniques that incapacitate an opponent very quickly, typically within the first two movements. Mitose revealed the Joint Striking and Locking, Push/Pull, and Evasion concepts to these men and they each applied it to their own arts. These talks also delved into breathing techniques, jumping patterns, nutrition, etc., basically, all of the things that Mitose had learned as a child growing up at his families temple in Japan, where he lived the life of a warrior-monk. All 5 of these men were certified as Masters of Kosho Shorei Ryu Kenpo Karate by Great Grandmaster James Mitose. Bruce Juchnik was appointed as Master #1.

Before his death, Mitose awarded Bruce Juchnik a full mastery certification (Menkyo Kaiden and Inka Shomei) and gave him a patriarchal copyright to kenpo, the "power to do whatever (Juchnik Hanshi) thinks is good and right for God, for (Mitose), and for Kosho Shorei, true self-defense, true and pure Karate and Kenpo" from that day forward.

Bruce Juchnik worked with Mitose’s first Black Belt, Professor Thomas S.H. Young from 1982 until the death of Professor Young in 1995 in order to better connect James Mitose’s early teachings from Hawaii in the 1940s with the new teachings transmitted to Bruce Juchnik in the 1970s and 1980s. Thomas Young was an active participating member in Juchnik Hanshi's organization, the Sei Kosho Shorei Kai International (S.K.S.K.I), until Professor Young’s death.

Juchnik currently serves as Director of the Sei Kosho Shorei Kai International and is the President of the Martial Arts Collective Society, a diverse group of leaders in the martial arts world. Mr. Juchnik has devoted tremendous energy in building unity in the martial arts, bringing together leaders of dozens of styles to further improve the community of martial arts. Hanshi produces an annual “Gathering” of masters from a myriad of martial arts styles, conducting training seminars and building friendship within the arts. Mr. Juchnik serves as President of the American Filipino & Indonesian Martial Arts Association Majut Payat.

Bruce Juchnik is ranked in several styles of martial arts, including Tang Soo-do, Arnis, Kung fu, as well as being a 3rd degree black belt in the Tracy System of Kenpo. Bruce Juchnik founded the Sei Kosho Shorei Kai International (S.K.S.K.I.). The Kai was developed to carry on and preserve the teachings of James Masayoshi Mitose.
