Review:

The head of Kyokushin-kan Karate, Kancho Hatsuo Royama wrote this first installment of the priciples of karate while still the head technical advisor of Kyokushinkai Kan Karate. This technical manual, the result of 40 years of karate training is in both Japanese and English uses continuous photos to show techniques with a simple to follow written instruction. This book coupled with the second rarer Gokui is a completes the skills of Budo Karate Kancho Royama would later use as a template for the foundation of Kyokushin-kan and its training syllabus therein.

Review by Stephen McCann:
As I wrote for the introduction of this book; Kancho Hatsuo Royama wrote this first instalment of the principles of karate while still the head technical advisor of Kyokushinkai Kan Karate.
This book uses continuous photos to show techniques with a simple to follow written instruction in Japanese and English. I use this book often as a reference tool.
This book coupled with the second Gokui are outstanding and in my opinion the two best books on Karate in my very large collection.
