Ninjutsu



Ninjutsu is a fighting style that is used by the ninjas of Dead or Alive (Kasumi, Hayabusa, Ayane, and Hayate. Ninjustsu sometimes used interchangeably with the term ninpō (忍法, ninpō?) is the martial art, strategy, and tactics of unconventional warfare and guerilla warfare practiced by the shinobi (commonly known outside of Japan as ninja). A female ninja is called a Kunoichi.

While there are several styles of modern ninjutsu, not all can be related to the historic practice of ninjutsu in Japan so as to be considered a koryū.

History
Ninjutsu was developed by groups of people mainly from the Iga Province and Kōka, 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 (ryū) have taught their unique versions of ninjutsu. An example of these is the Togakure-ryū. This ryū 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.[citation needed] 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.[5]

Skills relating to espionage and assassination were highly useful to warring factions in feudal Japan. Because these activities were seen as dishonorable, Japanese warriors hired people who existed below Japan's social classes to perform these tasks. These persons were literally called "non-humans" (非人, hinin?). At some point the skills of espionage became known collectively as ninjutsu,[citation needed] and the people who specialized in these tasks were called shinobi no mono.
