Book by Kim Ashida: Secret Ninja

All the secrets and techniques for becoming invisible. A detailed look at the tools used in ninjutsu and how they are used.

The study of an ancient and obscure form of martial art aimed at providing a comprehensive understanding of Ninjutsu.

The ninja was considered a master of weapons, and this volume provides a detailed explanation of the various tools and their uses. However, the study of the art of Ninjutsu as a whole does not require knowledge of any type of weapon, and as a famous master once said: "Ninjutsu can be practiced by a naked man in an empty room."

You can’t move quickly and silently if you’re loaded down with equipment that, if dropped, would certainly be confiscated. So what should you do? This book covers all the ways to make yourself invisible in the presence of the enemy, to enter anywhere without being seen, and to pass through without leaving a trace. This is the way of Ninjutsu: The Art of Invisibility.
