All Japan Karatedo Gojyuryukai

ABOUT Gōjū-ryū-kai Karatedo

Gōjū-ryū (剛柔流), (Japanese for "hard-soft style") is one of the main traditional Okinawan styles of karate, featuring a combination of hard and soft techniques. Both principles, hard and soft, come from the famous martial arts book used by Okinawan masters during the 19th and 20th centuries, the Bubiji (武備志). Gō, which means hard, refers to closed hand techniques or straight linear attacks; jū, which means soft, refers to open hand techniques and circular movements. Gōjū-ryū incorporates both circular and linear movements into its curriculum, combining hard striking attacks such as kicks and close hand punches with softer open hand circular techniques for attacking, blocking, and controlling the opponent, including locks, grappling, takedowns and throws. We are open for all aspiring students; be it young or adult, male or female, any race and nationality. Feel free to enter and feel how good it is to learn martial arts. Because here, we not only make you get strong physically, but also emotionally and mentally.
