Product Description


Ninjutsu has been variously described as the 'art of sneaking in', the 'art of stealth' and even the 'art of invisibility', and this book reveals the ninja's way of life that few outside of Japan have experienced. Ninja were the cloak-and-dagger artists of Japan's feudal era, from the late 13th century to the early 17th century. Japanese youths were trained within the Iga and Koga ninja networks, which were run like armed camps and turned out only espionage agents. Iga and Koga youths were born ninja and died ninja - there was no other way of life open to them. They were thus able to devote all their time to training, and they were considered full-fledged ninja when they were still in their teens.

Format: Paperback
This book is a general information book on the art of ninjutsu, and its followers. It touches on many aspects of it, yet not too deeply. It is a good book for someone who is seeking knowledge on the subject, about what he/she does not know a whole lot about. Unfortunately many who are familiar with the art will look at it and say, "oh, no, not another one". On the lighter side, I found no misrepresantions or bending of facts in the book. All that the author says is true, and he is knowledgable. I have also found that in my copy of the book about 30 pages toward the end have been reprinted, even with the same page number. So as it is, the pages go 1, 2,...87, 88, 65, 67.. So you get the same information twice. I do not know if it is only a misprint of my copy, or it is in all versions.

Bought this book years ago and what was so good about this book was that mr adams was a pure researcher and went to great lengths to find some of the few remaining masters who teach the art.Many people claim that there is only one master alive today but there are a few as mr adams has found out. If you read his book and have some knowledge on the art it all adds up so what does it matter anyway if they are a little different or use different names.To the outsider this is a great book that has been very well researched and presented..... highly recomended.

Written as it was at the end of the '70s, this book is really good because Andrew Adams is discovering about Ninjutsu before all the hype that we have today became prominent. Good for finding a basic history.

HASH(0x93d8ec18) out of 5 stars A general Ninja overview 19 Sept. 2000
By Grant Meredith - Published on Amazon.com
Format: Paperback
What we have here is a general overview of traditional Japanese Ninjutsu, the author has even featured and spoken to Grandmaster Hatsumi. The book has large B/W photos of Ninjas in various posers and off the unique weaponry of their warrior class. The book opens up with two chapters on the origins and history of the ninja, then its onto weaponry and some ingenious tools of the trade.Following chapters include : poisons and curatives, physical and mental training, strategy, espionage, warfare, penetration of enemy strongholds, tricks, escaping and hiding,famous ninjas in history and the modern day ninja. The book is generally quite informative and anybody interested in the art should be encouraged to read this. No specific techniques are shown and as I have said the book is very general in nature. Enjoy the read.

HASH(0x942da4d4) out of 5 stars The Book That Introduced Ninjutsu To The English Speaking World 16 Nov. 2005
By Michael Chesbro - Published on Amazon.com
Format: Paperback
Ninja: The Invisible Assassins is one of the first books to introduce ninjutsu to the English speaking world. My copy of this book was published in 1973.

"Cloaked in black from head to toe and concealing a small arsenal of deadly weapons and secret devices, these medieval masterminds of espionage, sabotage, arson and assassination moved stealthily but relentlessly across the pages of Japan's turbulent era, from the 13th to the 17th Centuries." Ninja developed the strangest and most chilling art ever to be brought forth from the vast reaches of Asia.

The ninja studied the skills of all of the martial arts of the day, as well as mastering a wide range of unique weapons. Andrew Adams explores many of these weapons, such as the `shinobi-zue' (a staff concealing a hidden chain), the kyoketsu-shogi (a hook-knife with a long cord and attached ring), the well-known shuriken (throwing stars and spikes), and many other weapons that fill the ninja's arsenal.

Poisons and curatives were part of the ninja's skills. The ninja's training allowed him to prepare gunpowder and explosives, medicines, poisons, and even concentrate and dehydrate foods to be used on long missions.

The ninja were also masters of strategy and espionage. Andres Adams gives us insight into these principles, and their historical application by the various ninja clans.

Finally, we are introduced to the leading ninjutsu masters of the modern day (the early 1970s), men such as Yoshiaki Hatsumi, Norihiro Iga-Hakuyusai, and Yumio Nawa.

If it can be said that there is a `classic ninjutsu book' it must be Ninja: The Invisible Assassins by Andrew Adams. This book is very well written, illustrated with several photographs and makes a strong effort to be historically accurate while still providing interesting and entertaining reading. If you could have only one book about ninjutsu, it should be this book!

HASH(0x9401f6f0) out of 5 stars Fun Read 18 April 2013
By John - Published on Amazon.com
Format: Paperback Verified Purchase
Though some of the work is a bit dated and current information has disproved some of the data, it is still a fun read for those of use who grew up during the "ninja craze".

By A Customer - Published on Amazon.com
Format: Paperback
Not bad for being published about 30 years ago (my copy says 1970,if I read it right) The author researched it well, citing several sources with the photo's provided by Soke Masaaki Hatsumi. Information on history and the development of the art while not exhaustive is useful to anyone researching Ninjutsu and it's origins. It does have sections on the weapons and other tools used by the historical ninja and does attempt to dispell some of the myths by explaining how the myths were possibly started. If you are a new student to the Bujinkan then you should consider taking a look for the historical perspective. Not a bad book overall, a bit dated in publishing technique and definatly not an exhaustive source of information but worth a look.

HASH(0x93d91024) out of 5 stars the ninja 10 Aug. 2011
By Jeff - Published on Amazon.com
Format: Paperback Verified Purchase
This is a great book to read for anyone beginning their exploration of ninjitsu. Its a good historical guide and is easy to read with lots of pictures, and alot of good fictional scenerios. Once you have a basic understanding though you will want to read more books by Hatsumi and other of Stephen Hayes works to get a more in depth picture of the ancient art. Great for anyone interested in learning more about the life of the ninja or beggining the art training.
