Beware of anyone who says they have a "no-touch knockout" technique

You see a few of these guys around on the internet.

They either hold a "15th degree" in some art, or they hold a "10th degree" in something like nine or ten different arts. 

Zen seven, ken three

"Zen seven, ken three" is a samurai saying that you hear in a martial arts dojo (training hall) even today. It means that technical ability with the sword (ken) or any other weapon is only 30 percent responsible for your success or failure.

The 70 percent factor (the Zen of the saying) in any battle—crossing swords in kendo, or solving a problem—is inside you. Inner training is devoted to cultivating that inner power.

In Praise Of Spies: Ninjutsu's Role In Shaping Japan - (2012)

Shinobi-no-jutsu played a crucial role in the history of Japan, yet its contributions have become almost completely forgotten. Based on actual shinobi manuals and intricate historical analysis, this book presents an accurate presentation of shinobi-no-jutsu and the role it played in shaping Japanese history.

"In Praise of Spies: Ninjutsu's Role in Shaping Japan" by Steven Nojiri is about Shinobi (aka Ninja) who were essentially highly trained covert agents in the feudal Japan era. The Shinobi specialized in unorthodox warfare which included the black arts of espionage, sabotage, infiltration, evasion and assassination, and overt combat in certain situations. Their covert methods of waging war contrasted the ninja with the samurai, who observed strict rules about honor and combat.

This book focuses on the "spying" aspect of the Shinobi. Espionage was the chief role of the ninja; with the aid of disguises, the Shinobi gathered information on enemy terrain, building specifications, as well as obtaining passwords and communiques, just information in general to develop plans of action. Overall intent of this book is twofold. First the author wanted to provide a reference to the effect indirect impact that Shinobi had on early Japanese history. Additionally the author has intended for this book to be a jumping-off point for the reader to investigate and delve deeper into the various topics through outside sources. Of note this book contains a significant amount of material that has never been printed in the English language. The material within this book is based on actual Shinobi manuals and intricate historical analysis presenting accurately the role played by the Shinobi in shaping Japanese history.

I highly recommend this book to anybody interested in spycraft, espionage, early Japanese history and Ninjutsu practitioners and historians. - T.A.L. Dozer

Sacred Conspiracy: A Commentary to the Fukushima Ryu Shinobi-no-Maki - (2015)

A commentary on the Fukushima Ryu Shinobi-no-Maki by Steven Nojiri. The commentary covers both the original Shinobi-no-Maki and the Annotations. Also included in this book is a brief survey of Kusunoki Ryu. This is not a strict history book. This is a book of commentary and personal opinion.

First of all, as explained by the author, "Sacred Conspiracy" is personal commentary concerning the legitimate historical documents of Fukushima ryu ninjutsu, as well as related subject matter. With that said, while it is not a collegiate history text book, it does indeed offer enjoyable insight into medieval Japanese warfare. Mr. Nojiri also provides his family's (the House of Nojiri) kuden (oral tradition) on this topic, in addition to just translation of historic documents. As oral tradition is not something easily corroborated by independent academia, a fact which is fully explained by Mr. Nojiri, it is up to the reader to determine its validity. I for one enjoyed the book immensely, as well as Mr. Nojiri's previous publication "In Praise of Spies", & do highly recommend reading it. - Thomas Urso
