What people say about our book?

I am a practitioner of Bujinkan in Japan. I have studied this art for more than 33 years. I live in Japan. Also one of my great passions is history, Japanese history but also any history that comes with conflict or great changes in human history. Why do I love this book? In this book I finally find a non native Japanese, who actually can Read and Speak Japanese and with great passion and skill have spend decades on finding hidden evidence on the Ninjas history in Japan. Many foreigners who writes about Ninjas in Japan does not speak Japanese and therefore have to rely on others. This limits them a lot and it shows in their various bestseller books about the Japanese Ninjas. How can you even find any facts on Ninjas besides the Shoninki, Ninpiden or Bansenshukai? This is where the foreign scholars get stuck( Anthony Cummins and Stephen Turnbull), because there is much more knowledge out there but you have to look for it in Japanese. What this author has taught me is there were so many more Ninja clans out there than I ever thought. He has opened a new door in the Ninja universe and I hope that more people will read this book and step through that door and do more research!!!

Whether you’re a martial artist, nipponophile or just love literature, this historical view into the real history of the ninja is outstanding. The author is in a unique position as both a scholar of Japanese language and history and as a long-time high level practitioner who has had a unique level of access and dialogue with Masaaki Hatsumi. The book is a delight to read and look at. Askew has a style of writing that satisfies the appetite of the academics or deeply committed enthusiasts of the subject yet tells the tale in a bright conversational style that explains as it goes so the reader is really able to get a clear understanding of the time and events. It is lavishly illustrated, almost every page has photographs or illustrations so it really captivates your attention fills your senses. This is a book that is joy to spend time with and the reader leaves as a well informed minor expert of the subject.

I have nothing but good things to say about this book. Secret societies in general are very difficult to gather information on; but Massaki Hatsumi has given us all a sneak peak into the world of Ninpo Tai Shin Gi Tai. Sean has done an amazing job researching this, and backs all of his claims with verifiable sources. I can’t wait to read the next book.
This was a fascinating story, tracing the Togakure ninja clan’s origins from Mt. Togakushi down to the well-known ninja hotbed of Iga. The discovery of Toda Shinryuken’s identity is hard to dispute. Not only does this book present a scholarly approach, with credible evidence tracing the Togakure Ryu lineage, I was surprised by the apparent links to falconry. I’m eager to read Mr. Askew’s next book.

Excellent historical look at the ninja. Finally a book that can make claims and show factual linkage with those claims. If your interested in the history of the Ninja and who was who, this is the book. Very well written. Highly recommend! 👍🏻👍🏻👍🏻
You can tell a lot of time was spent researching the history of this martial art! It was really well written and leaves you wanting to learn more. Anyone interested in history and martial arts will find something of interest and probably debate. Check it out!
