"The Essence of Ninjutsu." Written during the Ninja "boom" of the early 1900's, Gingetsu Itoh seeks to dispel the myth that Ninjutsu is an art comprised solely of magic and sorcery. The moving pictures and billboards of the day have lead "the average person to consider Ninjutsu to be a kind of sorcery or magic". The techniques within are as relevant today as those contained in The Art of War. Itoh "Sensei" shows how the skills of those practicing Ninjutsu came about and the way those same methods were verified on the battlefields of the century of fighting that was the Warring States period With arresting anecdotes from military logs of the period as well as insightful commentary as to how this knowledge can be applied, Itoh Sensei presents a complete picture of what was understood about Ninjutsu in the early twentieth century. First time in English. All original illustrations included. Fourth Edition.
