The first complete translation of the ultimate Ninja manual—a comprehensive guide to the arts of the ninja, including espionage, warfare, assassination, and more
 
In 1676, a ninja named Fujibayashi collected and combined information from the ninja clans of Iga—regarded to be the homeland of the ninja—and compiled it into an authoritative book. Known as The Bansenhukai, Fujibayashi's book has now been translated into English by the Historical Ninjutsu Research Team and is widely considered to be the ‘bible’ of ninjutsu, the arts of the ninja.

The Book of Ninja begins with an in-depth introduction to the history of Fujibayashi's scripture. The teachings themselves, appealingly rendered in this translation, then take us into the secrets of guerrilla warfare and espionage. We learn how to become the ultimate spy, whether through a network of spies or by hiding in plain sight. Through the stealth and concealment tactics of night-time infiltration, through weapon and tool building skills, and through mission planning, we can learn much both about warfare and about adopting the right mindset for tackling our own inner and outer enemies. Adding to the mix for the spycraft lover, there are sections on capturing criminals, performing night raids, making secret codes and signs, and even techniques for predicting the weather, and using an esoteric Buddhist system of divination. An exciting and engaging tome of lost knowledge, The Book of Ninja is the final say in the world of the ninja and the ultimate classic for samurai and ninja enthusiasts alike.
