Common Sense Self-Defense is an excellent text based on the Heike Ryu Ju Jitsu system, developed by Vince Tamura and his brother Mas Tamura. Vince Tamura, a 9th Dan, taught this Ju Jitsu system to his students, which is unique in that it only includes standing techniques and not ground techniques. Presented as a series of self-defense moves, Tamura and Shelton teach these all around amazing techniques in this book. A very interesting book with very descriptive, detailed photographs and explanations. Sensei Vince Tamura is a Judo Ju Jitsu pioneer and this book displays part of his teachings. Tamura was a descendant of the Taira Clan, and served in the US Army Combat Engineers of the First Cavalry Division during the Korean War, earning a bronze star.
