In Japanese history, a ninja is a warrior specially trained in a variety of unorthodox arts of war. These include assassination, illusion, espionage, and various martial arts.
The exact origin of the ninja is a matter of debate. It is known that ninja appeared in 14th century Japan and remained active from the Kamakura to the Edo period. The role of the ninja may have included sabotage, espionage, scouting and assassination as a method of destabilization or to cause social chaos. Such actions may have taken place at the service of a feudal lord (daimyo, shogun), or other entity waging guerilla warfare.
