Ninja
covert agent, mercenary, or guerrilla warrior in feudal Japan
A ninja (忍者; English: , Japanese: [ɲiꜜɲ.dʑa]), shinobi no mono (忍の者; Japanese: [ɕi.no.bʲi no mo.noꜜ]) or shinobi (忍び; Japanese: [ɕi.no.bʲi]) was a spy and infiltrator in pre-modern Japan. Antecedents may have existed as early as the 12th century. Despite popular belief, there is little evidence that ninja were assassins.
In the unrest of the Sengoku period, the jizamurai, peasant-warriors in Iga Province and the adjacent Kōka District, formed ikki – "revolts" or "leagues" – as a means of self-defense. They became known for their military activities in the nearby regions and sold their services as mercenaries and spies. Following the establishment of the Tokugawa shogunate in the 17th century, the ninja faded into obscurity.
Etymology
Ninja is the on'yomi (Early Middle Chinese–influenced) reading of the two kanji "忍者". In the native kun'yomi reading, it is pronounced shinobi, a shortened form of shinobi-no-mono (忍びの者).
The word shinobi appears in the written record as far back as the late 8th century in poems in the Man'yōshū. The literal meaning of shinobi (忍) is "to steal away; to hide" and—by extension—"to forbear", hence its association with stealth and invisibility.
