On his return to Okinawa he began to teach the martial arts out of his home in Naha. Later, he alsi taught at the Okinawan Prefecture Police Training center, at the Okinawan Master’s Training college, and at the Naha Commercial High School (where his teacher had once taught). Chojun Miyagi worked hard to spread Karate throughout Okinawa and mainland Japan, and to earn his toudi a status equal to that of the highly respected Japanese martial arts of Judo and Kendo. To achieve this he traveled frequently to mainland japan where he was invited to teach at Kyoto University, kansai University and Ritsumei Kan University. In 1933, Goju-Ryu Karate was the first martial arts in Japan. This was a milestone for Karate as it meant it would aligned with the highly respected martial arts of japan.
Chojun Miyagi dedicated his whole life to Karate. He was responsible for structing his toudi( which he later names Goju-Ryu) into a systemized discipline which could be taught to society in general. This teaching system that he formulated enabled karate to be taught in school for the benefits of the young, and to reach vast numbers of people throughout the world. However, his private teaching at his home remained strictly in adherence to the principle and traditions of his teacher, kanryo Higaonna, and his teacher before him, RuRuKo.
