Among the many karate technique books, the 7 items I am offering are uniquely rare works. While there are many detailed explanations of kata and other techniques in karate books, I believe there are few technique books that explain the use of the body in karate in detail. Even now, in his old age, Mr. Yanagawa is apparently able to perform the movements he explained in his books. I think it is quite rare for someone to be able to physically perform the movements and have them explained in their writings. I strongly recommend that you read Mr. Yanagawa's works. I believe that Mr. Yanagawa, who is small in stature and light in weight, can deliver strikes with superhuman speed and power because he correctly embodies the principles of karate according to his philosophy. It is difficult to understand these principles from a single book. I believe the items I am offering cover most of his works, so please purchase them and research Mr. Yanagawa's principles. ◆Set of 7 books. No individual sales.
