Chōjun Miyagi
was an Okinawan martial artist who founded the Gōjū-ryū school of karate by blending Okinawan and Chinese influences. Life

Early life and training
Sensei Miyagi was born in Higashimachi, Naha, Okinawa on April 25, 1888. One of his parents was a wealthy shop owner. Chojun Miyagi began studying Okinawan martial arts under Ryuko Aragaki at age 11. At age 14, Miyagi was introduced to Kanryo Higashionna (Higaonna Kanryō) by Aragaki. Under his tutelage, Miyagi underwent a very long and arduous period of training. His training with Higaonna was interrupted for a two-year period while Miyagi completed his military service, 1910–1912, in Miyakonojō, Miyazaki. Miyagi trained under Higaonna for 15 years until Higaonna's death in 1916. Training in China
In May 1915, before the death of Higaonna, Miyagi travelled to Fujian Province. In China he visited the grave of Higaonna's teacher, Ryū Ryū Ko. In this first trip he travelled with Eisho Nakamoto. After Kanryo Higaonna's death (in Oct, 1915) he made a second trip to Fuzhou with Gokenki. In this second trip he studied some local Chinese martial arts. It was in this second trip that he observed the Rokkishu (a set of hand exercises rather than a formal kata, which emphasizes the rotation of the forearms and wrists to execute offensive and defensive techniques), which he then adapted into the Tensho Kata. From the blending of these systems, and his native Naha-Te, a new system emerged. However, it was not until 1929 that Chōjun Miyagi named the system Gōjū-ryū, meaning "hard soft style". Return to Japan
After several months in China, Chōjun Miyagi returned to Naha where he opened a dojo. He taught for many years, gaining an enormous reputation as a karateka. Despite his reputation, his greatest achievements lie in popularization and the organization of karate teaching methods. In recognition of his leadership in spreading karate in Japan, his style, Goju-Ryu, became the first style to be officially recognized by the Dai Nippon Butokukai. He introduced karate into Okinawa police work, high schools and other fields of society. He revised and further developed Sanchin - the hard aspect of Goju, and created Tensho - the soft aspect. These kata are considered to contain the essence of the Goju-ryu. The last kata taught in most dojos, Suparinpei, is said by some to contain the full syllabus of Goju-ryu, although this assertion is disputed. Shisochin was Miyagi's favorite kata at the end of his years. With the goal of unification of various karate styles which was in fashion at that time (see Gichin Funakoshi for his works in Japan), he also created more Shuri-te-like katas known as Gekisai Dai Ichi and Gekisai Dai Ni in 1940, taking techniques from higher forms (notably Suparinpei, and upper blocks uncommon for Goju-ryu at that time) and incorporating them into a shorter forms. It is said he created these kata to bridge the gap between Sanchin and Saifa, which contains much more complex moves compared to Sanchin, as well as to have forms to teach to his students in the Prefectural Teacher's College. Death 

Miyagi had his first heart attack in 1951, and died in Okinawa on October 8, 1953, from a second heart attack. Successor
Miyagi died without having officially named a successor, and several of his pupils have proclaimed themselves as his successors. However, Seikichi Toguchi is quoted as saying “Let me first say that I was not named the successor of Goju-Ryu by Miyagi, but nor was anyone else. There are some Goju-Ryu teachers who claim to have been privately appointed successor by Miyagi. These claims are ludicrous and disrespectful of his memory. He never publicly named anyone as successor. Common sense would dictate that if he were to appoint someone, it would have been a longtime student and it would have to be of public record to have any value." After Miyagi's death, his most experienced pupils at the time of his death were Sekō Higa, Meitoku Yagi, Eiichi Miyazato, Koshin Iha, and Seikichi Toguchi. The family of Chojun Miyagi communicated that the founder of the style wanted Eiichi Miyazato to succeed him. The Goju Ryu committee, formed by major students of Miyagi (which included among others Nakaima, Madanbashi, Meitoku Yagi, Iha Koshin) at a meeting in February 1954 voted almost unanimously Eiichi Miyazato as the official successor to Chojun Miyagi. Miyazato continued to teach from Miyagi’s Garden Dojo until 1957, when he built the Jundokan dojo with the help of the Miyagi family. Miyagi's family also donated Hojo Undo tools and Miyagi's Busanagashi statue to Miyazato, which became the symbol for the Jundokan. Another important recognition was made by Miyagi's family in 1963 to Meitoku Yagi, publicly recognizing him as one of the successors of Miyagi and giving him one of Miyagi's karate gis and belts. Later other students would proclaim themselves Miyagi's successors like An’ichi Miyagi (a claim supported by Morio Higaonna, who claims An'ichi as his main teacher) or Gōgen Yamaguchi, whom Peter Urban (in his book The Karate Sensei) says was named in Miyagi's will as successor. Legacy 

Some of Miyagi's more notable students were Seko Higa (also a student of Kanryo Higaonna), Miyazato Ei'ichi (founder of the Jundokan dojo), Meitoku Yagi (founder of the Meibukan dojo, Seikichi Toguchi (founder of Shorei-kan Goju-ryu), and on the Japanese mainland Gōgen Yamaguchi who was the founder of the Gōjū Kai in Japan. The character of Mr. Miyagi in the Karate Kid film series, written by Robert Mark Kamen (a Goju Ryu student of Toguchi - Kayo Ong lineage), was inspired by Chōjun Miyagi. Writings
