In this book, Dr. Maasaki Hatsumi, 34th Grandmaster of Togakure Ryu Ninjutsu provides the reader with a true glimpse of what it really meant and means to be a practicioner of ninjutsu. Dr Hatsumi discusses the history and evolution of Ninjutsu as well as its uses and applications during fuedal era Japan and beyond. He provides exceptional illustrations, photos, and artwork of various ninja weapons, techniques, and tools. Dr Hatsumi also shares with the reader a paper on ninjutsu written by his teacher or sensei, Toshitsugu Takamatsu. In his paper Takamatsu sensei describes what being a ninja is. He discusses the ninja's duties and responsibilities along with how their influence on certain events should be felt. Whether you are a student of ninjutsu or just an interested reader, this book is a must read! I felt this book went a long way towards dispelling many of the misperceptions often associated with the art of ninjutsu.
This book was written in 1980 and, at the time, it was one of the only sources of reliable information about Ninjutsu. It was written mainly to combat the myths surrounding Ninjas (caused by their portrayal in popular media), but also to stem the claims made by several 'movie Ninjas' that they were actually masters of the art. The book is a declaration, and illustration of proof, that Masaaki Hatsumi is the ONLY surviving Grandmaster of Ninjutsu. At the time of writing Dr Hatsumi's organisation was known as 'Togakure ryu Ninpo Taijutsu'. This book reflects this by focusing upon only one ryu (school) of Ninjutsu- Togakure ryu (whereas there are actually 9 ryu in Dr Hatsumi's current organization- Bujinkan Budo Taijutsu). This doesn't detract from the value or relevancy of this book when studying Ninjutsu's history ... but does make it a simplified and incomplete story. You will need to look elsewhere for a history of the other ryu. This book is NOT a how-to manual for a Ninjutsu student. Although it does contain some invaluable insights about the essence of Ninjutsu, the book has no techniques and little advice on how to improve your form. As suggested by the book's title, it is a reference source about Ninjutsu's history (and over half the book is dedicated to the weapons used by the Ninja). If you want to learn the martial art of Ninjutsu this book will not, nor does it claim to, substitute for tuition by a Bujinkan dojo's instructor (just as you can't learn to drive by reading a history of the automobile, you can't learn the art of Ninjutsu by reading this book). A lot has changed in the world of Ninjutsu since 1980 and other good, reliable sources of information about Ninjutsu (much of it also written by Dr Hatsumi) now exist. This book is accordingly not as valuable as it once was. However, if you know little about Ninjas (other than their incredible mythology) and would like to know the truth, or are looking for an encyclopedia of Ninjutsu weaponry then this is the book for you.
