Thank you KenpoDavid, it is always a concern of mine that Shorinji Kempo gets related to American Kempo. It is quite different and there is no connection or linage with any other style. Doshin So based his art on his experiences when studying martial arts at the Shoalin Temple. When he returned to Japan he re-visited some other arts he had learned earlier. He then developed Shorinji Kempo, restructuring all of his experience so that the end result was a well-integrated form of self-defence. I have seen Doshin So listed in the geneology of Aiki Jutsu, and it is true that he studied this older form of Jujutsu and many of our techniques look similar; however it is also true that Aiki Jutsu originally came from China. The name, Shorinji Kempo, has needed protection to stop some people claiming linage or trading on its success. Shorinji Kempo is the most popular martial art in Japan now, and WSKO is the biggest single martial art organisation in the world. With the growing awareness of Shorinji Kempo in the west there has been quite a lot of people claiming to have trained in it, or hold black belt status. What they don't understand is that WSKO keeps records of all members, and will act to protect the name and reputation of Shorinji Kempo.
