I have trained and I know this Great Martial Arts Master for over 23 years
This is a book that looks at the deeper and hard to understand part of his
art I look foward to reading his books and enjoying his training.
This book is the first in a series of three important books by Hatsumi Sensei. The first two have been written and released within the last five years, the third one will be released soon.
1. The Way of the Ninja
2. Advanced Stickfighting
3. Japanese Kenjutsu
I might be wrong about the title of the third book as it has not been released, but that is the subject. These books are filled with amazing photographs and some pretty high-level concepts in the text.
These books contain secret techniques that a non-Bujinkan student may have trouble deciphering.
In any event, there is much truth and wisdom written in between the lines and I cannot recommend them highly enough. Honestly, there really aren't any other authors that are worth reading when it comes to this subject. If you want to study real ninjutsu, start with these books.
