>> Vol. 1- Techniques of Kotegaeshi (Reverse Hand) Shuyokan Ryu is a martial art teaching system made up of techniques taken from the traditional martial arts of Yoshinkan Aikido, Kodokan Judo and Jujitsu, and Shotokan Karate Jutsu. Shuyokan Ryu stresses, “self defense”, not fighting. The founder and headmaster, Soke David Dye, has taken these techniques and put them into a practical form of martial art based on his 34 years as a police officer in California and his martial arts training and teaching since 1962. His self-defense system is better known as the “Samurai Cops System of Self-Defense”. This Aikido series is a three volume set covering the complete style of Shuyokan Ryu Aikido.
