When Master Shimabuku formed Isshinryu, he did so by “blending” the best techniques from both Shorin-Ryu and Goju-Ryu, in addition to employing techniques that were unique to his own design. Taking what he learned from other styles, and molding it to fit his philosophy of what the ultimate fighting art should provide, Isshinryu is the living example of all the martial arts and life influences that were Tatsuo Shimabuku.
