In this unique book, the author reveals for the first time the specific details of the long-held secret knowledge of Kappo - Sappo, the esoteric cure or kill techniques of the ancient jujitsu systems of Japan. By definition, cure or kill means that the same points one stimulates to start a person's heart or breathing that has stopped are the same points one stimulates to stop someone's heart or breathing. The author, who has studied with the most senior teachers of four branches of the Okazaki tradition, presents the extensive collection of the Kappo techniques of the Kodenkan - Dan Zan Ryu jujitsu system of Master Henry Okazaki; he explains in extensive detail more than 53 Kappo techniques, options, and variations, as well as examining the traditions of secrecy that surround this subject. In keeping with the Okazaki example and spirit, he is one of the first teachers to break with the tradition of secrecy surrounding Kappo - Sappo. This knowledge is necessary for all serious students of martial arts, and should be relevant to anyone with an interest in traditional Japanese medicine, trauma medicine, natural cures, restorative medicine, and/or Traditional Chinese Medicine.
