Karate gained global attention following its inclusion in the 2020 Tokyo Olympics (held in 2021), though it had already enjoyed widespread popularity, with an estimated 130 million practitioners worldwide. For Japan, the birthplace of karate, this recognition is a profound honor. The author deeply respects the early pioneers of all karate styles who, soon after World War II, spread karate internationally, relying solely on their skills.

As globalization accelerates, the author hopes to introduce more people to the beauty and depth of budō karate, rooted in Japanese culture and traditional values. This book reflects his insights, accumulated experiences, and training philosophy, and is offered in the hope that it will serve as a meaningful guide to readers on their own karate journey.
