The traditional Japanese method of espionage; involves stealthy movements and the use of camouflage.
Ninjutsu was developed by groups of people mainly from the Iga Province and K?ka, Shiga of Japan.
Throughout history the shinobi have been seen as assassins, scouts and spies. They are mainly noted for their use of stealth and deception. They have been associated in the public imagination with activities that are considered criminal by modern standards. Throughout history many different schools (ry?) have taught their unique versions of ninjutsu. An example of these is the Togakure-ry?. This ry? was developed after a defeated samurai warrior called Daisuke Togakure escaped to the region of Iga. Later he came in contact with the warrior-monk Kain Doshi who taught him a new way of viewing life and the means of survival (ninjutsu).
Ninjutsu was developed as a collection of fundamental survivalist techniques in the warring state of feudal Japan. The ninja used their art to ensure their survival in a time of violent political turmoil. Ninjutsu included methods of gathering information, and techniques of non-detection, avoidance, and misdirection. Ninjutsu can also involve training in disguise, escape, concealment, archery, medicine, explosives, and poisons. Skills relating to espionage and assassination were highly useful to warring factions because these activities were seen as dishonorable. The Japanese warriors hired people who existed below Japan's social classes to perform these tasks, these persons were literally called "non-humans". At some point the skills of espionage became known collectively as ninjutsu,and the people who specialised in these tasks were called shinobi no mono.
In the late 1970s and early 1980s ninjutsu became famous through many action films, Sho Kosugi a practitioner of ninjustu became famous through these movies.
