There has never been such a book - not only in Russia, but also in any of the European languages. This is the only complete NINJA encyclopedia based on authentic Japanese sources. All about the military art of ninjutsu and the legendary "invisible" warriors, nicknamed "demons of the night" (the word "shinobi," which is synonymous with "ninja," means "scout-saboteur" in Japanese). The origin of ninjas and the genesis of their unique fighting skills, the formation and flowering of ninjutsu in the era of internecine wars and its decline under the shogunate, the "code of honor" and secrets of skill, the greatest "schools" and "clans" of ninjas, their weapons and equipment, firepower and spy devices, medicines and poisons - there are no secrets for this encyclopedia!
