Ninja, The Secret History of Ninjutsu: Ancient Shadow Warriors of Japan
Here, for the first time, is an in-depth, factual look at the entire art of ninjutsu, including the emergence of the ninja warriors and philosophy in feudal Japan; detailed historical events; its context in the development of other schools of martial arts; and the philosophies and exercises of the school today.
Based on more than ten years of study and translation of authentic Japanese texts, including many that have never before been translated, this is the most comprehensive and accurate study of the art of ninjutsu ever written outside of Japan. This ninja book includes studies of ninjutsu history, philosophy, wisdom, and presents a wide range of information from authors, historians, chronicles and scrolls in order to foster a deep understanding of this "shadowy" art.
For those who train in ninjutsu, for other martial art practitioners, for historians, and for anyone with an interest in Japanese feudal history or Japanese martial arts, The Ninja: The Secret History of Ninjutsu shines a light on this enigmatic subject.
