A community portal about Ninja with blogs, videos, and photos. Ninja were agents of a fourteenth century Japanese secret mercenary organization for stealth operations. They acted in feudal Japan, from Kamakura period to Edo period. Their missions included scouting, espionage, sabotage, and assassination, usually for feudal rulers (daimyo or shogun). Verifying information about ninja is a very difficult task. The secrecy in the organization and operations makes any related subject difficult to verify; with ninja, this is further compounded by the specific circumstances of its occurrence in distant lands using a different language, and the myth arisen around them. This compounded dificulty in verification is made nearly impossible by the stealthy lifestyle and multitude of dispatched victims of the ninja. Dead men tell no tales, and, as such, there are very few records of these shuriken-wielding silent killers.
