Isshinryu (pronounced "e-shin-roo") is an Okinawan karate style founded by Tatsuo Shimabuku (1908-1975) in January 1954.  Isshinryu, literally translated, means "one heart style" or "one heart method".  It is the blending of the strong, direct line attacking of Goju-ryu karate and the quick circular movements of Shorin-ryu karate. Shimabuku Sensei was a recognized master student in each of these prominent Okinawan fighting styles.  Isshinryu is sometimes referred to as "jungle warfare" style of karate due to the low snapping kicks and rapidly retracting hand strikes.  Isshinryu is designed for close-range encounters while also making use of throws, joint locks, and a limited amount of ground fighting
