Ninja (Japanese: 忍者 Ninja) or Shinobi (Japanese: 忍) as a group began writing about them in the fifteenth century as combat organizations that dominated the regions of Iga and Koga in central Japan, although the methods of guerrilla warfare and espionage operations began long before that.
At this time, confrontations between the daimyo clans took place in small areas, and guerrilla warfare and assassinations began as a valuable alternative to the forward attack. Since Bushido, the samurai symbol has forbidden these methods as dishonorable actions, the daimyo did not expect to accomplish his required tasks depending on his special forces, so he had to buy or request support from the ninja to perform selective strikes, espionage, assassination and infiltration into enemy strongholds.
It is rumored that some of the daimyo clans were ninjas and used their role as ninja hunters to dispel suspicion of their involvement in "dishonorable" ninja methods and training. Although classified as killers, many of them were literal fighters. In Hayes' book "The Secret Arts of Ninjas", Hattori Hanzo, one of the most famous ninja fighters, is depicted in a shield similar to that used for samurai fighters. He states that those who recorded the history of the ninjas had high positions in military dictatorships, and that a history student should To understand that the history of the Ninja was recorded by observers who wrote about their activities as seen from the outside.
Ninjutsu has not been a well-defined art since it began, and several eras had passed before the establishment of Ninjutsu as an independent knowledge system with its own rights, the art of Ninjutsu developed as an illegal and anti-samurai culture, which is why the origins of Ninjutsu are covered in centuries of ambiguity, concealment, and intentional confusion.
