Kousaku Yokota's fourth book, Karatedo Paradigm Shift, goes beyond the boundaries of Shotokan as he expands his research to cover aspects of Okinawan karate and concepts from other styles.

In this book, Yokota addresses topics such as training and physiology and also talks about the technical and philosophical aspects of the art. He also takes this opportunity to revisit Tekki/Naihanchi, which, unfortunately, seems to have lost its importance in Shotokan despite the fact that it is one of the most important kata in many Okinawan karate styles.

Readers of Karatedo Paradigm Shift will benefit greatly from this work. The research carried out by Kousaku Yokota and the thoughts and concepts that he introduces will enable readers of all styles and abilities to progress further in their karate journey, both physically and psychologically.
