Isshinryu History

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 a "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.Mizugami

The Isshinryu patch, designed by A.J. Advincula, is called 'Mizugami.' The patch was approved by Master Tatsuo Shimabuku in 1961 and stands as the only Shimabuku-approved patch in the Isshinryu system.The upright oval shape is indicative of the vertical fist, which is a trait unique to Isshinryu karate. The churning water represents the unstable, sometimes violent world of the karate-ka. The gray skies in the background symbolize calm, and the orange border symbolizes a ring of fire, which Shimabuku Sensei saw in a dream. The dragon represents Shimabuku Sensei himself, as his nickname, Tatsuo, translates to "dragon boy." The three gold stars represent Shimabuku Sensei's 3 master instructors - Chotoku Kyan, Choki Motobu, and Chojun Miyagi (the original Mr. Miyagi).

The figure in the center is the Megami ("goddess"), a half-snake half woman that represents both strength and quiet character. This figure also appeared to Shimabuku Sensei in a dream. The raised fist shows the ability of the karate-ka to fight if necessary while extending the open hand in a gesture of peace.
