Along with Gichin Funakoshi and Masatoshi Nakayama, Okazaki helped found the Japan Karate Association's instructor training program.

Later that year, it was decided that Okazaki would be trained as a "test case" for the still formulating JKA Instructor Trainee Program.

As part of an effort by Nakayama to spread the practice of Shotokan karate internationally, Okazaki came to the United States in 1961.

Originally planning to stay only six months, he later opened a dojo in Philadelphia, Pennsylvania and settled there permanently.

This decision came following Okazaki's concern that the JKA had not been conducting itself in the manner appropriate to the teachings of Master Gichin Funakoshi.
