Ninjutsu

Spying in Japan dates as far back as Prince Shōtoku (572–622). According to Shōninki, the first open usage of ninjutsu during a military campaign was in the Genpei War, when Minamoto no Kuro Yoshitsune chose warriors to serve as shinobi(ninja) during a battle. This manuscript goes on to say that during the Kenmu era, Kusunoki Masashige frequently used ninjutsu. According to footnotes in this manuscript, the Genpei War lasted from 1180 to 1185, and the Kenmu Restoration occurred between 1333 and 1336.[3] Ninjutsu was developed by the samurai of the Nanboku-cho period, and further refined by groups of jizamurai mainly from Kōka and the Iga Province of Japan in later periods. From circa 1460 to 1574 and 1581, respectively, these jizamurai led Kōka and Iga as de facto independent confederacies – the Kōka and Iga ikki – and formed an alliance together which persisted until the conquest of Kōka by Oda Nobunaga in 1574.

Throughout history, the shinobi were assassins, scouts, and spies who were hired mostly by territorial lords known as daimyō. Despite being able to assassinate in stealth, the primary role was as spies and scouts. Shinobi are mainly noted for their use of stealth and deception. They would use this to avoid direct confrontation if possible, which enabled them to escape large groups of opposition.

Many different schools (ryū) have taught their unique versions of ninjutsu. An example of this is the Togakure-ryū, which claims to have been developed after a defeated samurai warrior called Daisuke Togakure escaped to the region of Iga. He later came in contact with the warrior-monk Kain Doshi, who taught him a new way of viewing life and the means of survival (ninjutsu).[2]^: 18–21

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 involved training in disguise, escape, concealment, archery, and medicine. Skills relating to espionage and assassination were highly useful to warring factions in feudal Japan. At some point, the skills of espionage became known collectively as ninjutsu, and the people who specialized in these tasks were called shinobi no mono.

Today, the last authentic heir of ninjutsu is Jinichi Kawakami, the 21st head of the Koga Ban family, honorary director of the Ninja Museum of Igaryu, and professor at Mie University, specializing in the research of ninjutsu.[4][5] In 2012, Kawakami chose to be the end of his line of ninjutsu, stating that the art has no practical place in the modern age.[6]
