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 Bubishi (Chinese: 武備志; pinyin: Wǔbèi Zhì).
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 joint locks, grappling, takedowns, and throws.
Major emphasis is given to breathing correctly in all of the kata but particularly in the Sanchin kata which is one of two core kata of this style
The development of Gōjū-ryū goes back to Higaonna Kanryō, (1853–1916), a native of Naha, Okinawa. Higaonna began studying Shuri-te as a child. He was first exposed to martial arts in 1867 when he began training in Luohan or "Arhat boxing" under Arakaki Seishō, a fluent Chinese speaker and translator for the court of the Ryukyu Kingdom.
In 1870, Arakaki went to Beijing to translate for Ryukyuan officials. It was then that he recommended Higaonna to Kojo Taitei, under whom Higaonna began training.
With the help of Taitei and a family friend, Yoshimura Chomei (who was an Udun or Prince) Higaonna eventually managed to set up safe passage to China, lodging, and martial arts instruction. In 1873 he left for Fuzhou in Fujian, China, where he began studying Chinese martial arts under various teachers.
