98 free Ninja trivia questions with answers — history quiz, new questions added Oct 2026.
The real shinobi were spies, scouts and arsonists for hire from two mountain districts of central Japan, and almost nothing about the black-clad assassin of the movies survives contact with the records. The black costume comes from kabuki stagehands, the straight "ninja sword" cannot be traced before 1956, and the best-known ninja of all, Hattori Hanzo, was a samurai general famous for his spear. These 98 questions cover the history (Iga and Koga, the Sengoku mercenaries, Oda Nobunaga's 1581 invasion, the Shimabara Rebellion, the Edo-period manuals), the kit (shuriken, makibishi, nightingale floors built to defeat them), the famous names (Hanzo, Fuma Kotaro, Ishikawa Goemon boiled alive in Kyoto), and the pop culture that followed: Enter the Ninja, Ninja Gaiden, the Teenage Mutant Ninja Turtles, Naruto and the Sasuke obstacle course that became Ninja Warrior. Easy questions cover the words and the weapons; harder ones ask about clan politics, manuscripts and Mie University's ninja research centre. Every answer is cited to a page we checked, with a short explanation so you learn something even when you miss. Play it solo or print it for a history round.

Q 02Ninja sometimes travelled disguised as komuso, wandering flute-playing monks who hid their faces under what?

Q 03Which 1967 James Bond film sends 007 to train with ninja in Japan?

Q 08Films cast ninja as assassins, but what was their chief role in the historical record?
Espionage
Espionage came first: like modern spies, ninja gathered intelligence on an enemy's strength, and the sword-swinging assassin is an image that came from movies and comics.

Arson was the usual method: an abbot's diary for 1541 records men of Iga slipping into Kasagi Castle in secret and setting fire to the priests' quarters.
Q 10The oniwaban, spies who took over from the shogun's Iga and Koga guards, were named for which part of Edo Castle?

Matsuo Basho
Q 21Makibishi, used to slow pursuers, are the Japanese version of which weapon?

Q 23Despite his ninja reputation, what was Hattori Hanzo's actual station in life?
A samurai general
Matsuo Basho came from Iga and walked for months through northern Japan in his forties, so a 1966 book imagined him on a secret shogunate mission; a Mie University scholar who checked found his pace no faster than other fit travellers'.
Q 14The famous 1676 ninja manual compiled from Iga and Koga knowledge is called what?
Bansenshukai

Q 16The black ninja costume of fiction is thought to imitate which figures from Edo theatre?
Kuroko stagehands
Kuroko stagehands wore black so that audiences would ignore them, and dressing a stage ninja the same way is thought to have made his attack a surprise; real ninja wore ordinary, unremarkable colours.
Q 17Which 2019 FromSoftware game, starring a one-armed shinobi called Wolf, won Game of the Year at The Game Awards?
Sekiro
Sekiro began as a new entry in Tenchu, the ninja stealth series its studio owns, before outgrowing the idea; the title is a contraction of the Japanese for 'one-armed wolf'.
Q 18Which Japanese castle's 'nightingale floors' chirp when walked on, long said to warn of intruders?
Nijo
Nijo Castle's corridors chirp because clamps under the boards move against nails, and the castle itself calls the intruder-alarm story a mistake.
Q 19What does the word shuriken literally mean?
Hand-hidden blade
Hand-hidden blade is the literal reading: small enough to palm, shuriken were carried by samurai as well as ninja, and were meant more to distract an opponent than to kill.
Q 20Shuriken were reportedly left lying in plain sight, coated in what?
Poison
Poison is what the reports describe, meant for whoever picked one up; shuriken could also be wrapped in a lit fuse and thrown to start fires, or planted in the ground to injure anyone who stepped on them.

Q 27A retired swordsmith named Hattori Hanzo forges the heroine's blade in which 2003 film?

Q 28A viral 2019 Facebook joke proposed 'Naruto running' past the guards of which US site?
Area 51
Area 51's mock raid drew more than two million sign-ups on the theory that the arms-back anime run would outpace bullets, and law enforcement in Nevada took it seriously enough to issue warnings.
