Question: are ninja chinese or japanese?
Answer: A ninja (忍者, Japanese pronunciation: [ɲiꜜɲdʑa]) or shinobi (忍び, [ɕinobi]) was a covert agent or mercenary in feudal Japan. The functions of a ninja included espionage, deception, and surprise attacks. Their covert methods of waging irregular warfare were deemed dishonorable and beneath the honor of the samurai.
