Gōjū-Ryū was co-founded by Chojun Miyagi, and is one of the four recognized major styles of Karate in the world today. In 1930, Gōjū-Ryū was the first major style registered with the Dai Nippon Butoku Kai, the Japanese governmental organization dedicated to the preservation and promotion of Japanese martial arts. Also listed as a co-founder of the style was Kenwa Mabuni, founder of Shito-Ryu karate. Miyagi (and Mabuni) trained under Naha-te master Kanryo Higaonna. Gōjū-Ryū means "hard-soft style."

* Major emphasis is given to breathing correctly. Gōjū-Ryū practices methods that include body strengthening and conditioning, its basic approach to fighting (distance, stickiness, power generation, etc.), and partner drills. Gōjū-Ryū incorporates both circular and linear movements into its curriculum. Gōjū-Ryū combines 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.

Miyagi and Mabuni were best of friends. It was Miyagi who introduced Mabuni to Higaonna. Soke Kenzo Mabuni (son of Kenwa Mabuni and heir to the Shito-Ryu style) often referred to Miyagi as his "uncle from Okinawa."
