"The Cat"
Gōgen Yamaguchi was also famously known in the world of karate-dō as ‘the Cat’; he was a very small man, just over five feet (1.52 meters) and a mere 160 pounds (73 kg); however, he projected the impression of great bulk and an aura reminiscent of the samurai era. He was first dubbed 'the Cat' by American GI’s for his gliding walk and flowing hair. He alone was primarily responsible for the spread of Gōjū-ryū throughout the world today whereby hundreds of thousands of practitioners have experienced some form of training within traditional and non-traditional karate dojo.

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 locks, grappling, takedowns, and throws.

Major emphasis is given to breathing correctly in all of the katas but particularly in the Sanchin kata which is one of two core katas of this style. The second kata is called Tensho, meant to teach the student about the soft style of the system. Gōjū-ryū practices methods that include body strengthening and conditioning, its basic approach to fighting (distance, stickiness, power generation, etc.), and partner drills.

Kata
Gōjū-ryū has 12 core kata in its standard curriculum: gekisai (dai ichi & dai ni), saifa, seiyunchin, seisan, saipai, shisochin, sanseiru, kururunfa, sanchin, tensho, and suparenpai. Students in most schools are required to know all of these kata before reaching sandan.

Morio Higaonna writes that "Karate begins and ends with kata. Kata is the essence and foundation of karate and it represents the accumulation of more than 1000 years of knowledge. Formed by numerous masters throughout the ages through dedicated training and research, the kata are like a map to guide us, and as such should never be changed or tampered with."

Almost all of the kata have a corresponding bunkai oyo, a prearranged two-person fighting drill. These drills help the student to understand the applications of the kata, establish proper rhythm/flow, to practice constant attack/defense, and to safely practice dangerous moves on a partner.

Sanchin
Sanchin (Kanji: 三戦; Katakana: サンチン) means "three battles". This kata is a sort of moving meditation, whose purpose is to unify the mind, body and spirit. The techniques are performed very slowly so that the student masters precise movements, breathing, stance/posture, internal strength, and stability of both mind and body.

Sanchin is the foundation for all other kata, and is generally considered to be the most important kata to master. When new students came to Miyagi, he would often train them for three to five years before introducing them to sanchin. He would make them train very hard, and many of them quit before learning sanchin. Those that remained would focus almost exclusively on sanchin for two to three years. Miyagi's sanchin training was very harsh, and students would often leave practice with bruises from him checking their stance.
