The content of this book is the culmination of a life long quest for martial arts knowledge and expertise by Grand Master Ed Hartzell (Soke). The founder and creator of the Shin Ju Ryu Kenpo Jujutsu self defense system. Shin Ju Ryu Kenpo Jujutsu is a comprehensive and well rounded self defense martial art system. The base root of Shin Ju Ryu Kenpo Jujutsu can be traced back historically to both Japanese and Chinese martial arts through the lineage of James Masayoshi Mitose. James Mitose brought his family art, Kosho Shorei-ryu Kenpo to the U.S. (Hawaii) from Japan in 1937. Kosho Shorei-ryu Kenpo can be further traced back to the Shaolin Monks and the Kung Fu arts in China. Kosho Shorei-ryu Kenpo consists of both spiritual arts and martial arts. After the bombing of Pearl Harbor in 1941, James Mitose renamed the system he was teaching to Kenpo Jiu-Jitsu. This was only the martial art component of Kosho Shorei-ryu Kenpo, due to being in war time. Thus, the lineage is; Grand Master Ed Hartzell received training from Grand Master Nimar Hassan; who received training from Grand Master James Mitose.
