ninjutsu
LowTechnical/Specialist (martial arts), Informal (popular culture)
Definition
Meaning
The traditional Japanese martial art, strategies, and techniques of espionage and guerrilla warfare practised by the shinobi (ninja).
While primarily a martial art, the term is also used in popular culture to refer to ninja skills and abilities, often depicted with supernatural elements. Figuratively, it can denote any highly skilled, stealthy, or strategic manoeuvring.
Linguistics
Semantic Notes
In its traditional sense, ninjutsu is a complete system of martial arts, survival, and espionage, not just 'stealth' or 'assassination'. The modern, popular-culture usage often exaggerates or fictionalizes its capabilities.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'дзю-дзюцу' (jūjutsu) or 'джиу-джитсу'. Ninjutsu is specifically ninja arts, not general hand-to-hand combat.
- Avoid translating it as 'шпионаж' (espionage) only, as it encompasses a much broader set of survival and martial skills.
Common Mistakes
- Pronouncing it as /ˈnɪn.dʒʌt.su/ (nin-jaht-soo) instead of /nɪnˈdʒʊt.su/ (nin-JOOT-soo).
- Using it as a countable noun (e.g., 'He knows many ninjutsus') instead of an uncountable one.
- Confusing it with generic 'ninja moves' from films.

FAQ
Frequently Asked Questions
No. Historically, it was a comprehensive system for guerrilla warfare, espionage, survival, and information gathering. Assassination was one potential application among many.
Only informally or humorously (e.g., 'I used some office ninjutsu to get the last biscuit'). In formal contexts, it refers specifically to the Japanese martial art.
While arts like judo and karate are often sports or systems of direct combat, traditional ninjutsu focused on asymmetric warfare: espionage, sabotage, escape, and using the environment to survive, not necessarily winning a fair fight.
Yes. 'Jutsu' (術) means 'art', 'technique', or 'skill'. So 'ninjutsu' is the 'art of stealth/perseverance', and 'jujutsu' is the 'gentle/soft art'.
