Masatoshi Nakayama Sensei, one of the main disciples of the founder of Karate, Gichin Funakoshi, and Chief Instructor of the J.K.A, was one of the most prominent characters in the history and evolution of modern Karate. A month before his death in April 1987 at the age of 74, Nakayama Sensei welcomed Salvador Herraiz at his home in Tokyo, in the last interview in his life. In it the Master reviewed the key moments in the history of Karate, in his life, in the J.K.A, and also spoke of his philosophy and the dangers that lurk in Karate for the excessive and wrong competitive and sportive approach. Nakayama was undoubtedly the father of J.K.A. until his death, and after his passing, the organization was divided into two branches. The union disappeared with him.
