How to say "invasion" in Japanese

Choosing the right word
  • 侵入しんにゅうJLPT N2approx.Common
    noun, suru verb, intransitive verbThe broadest word for physically entering or intruding into a place — a building, property, network, or another's territory. For the invasion of a country as a political act, 侵略 or 侵攻 fits better.
    「ピッキングの道具どうぐ無なしで、どうやって侵入しんにゅうした?」「トイレの窓まどがあいた」↗
    "With no picks how did you break in?" "The toilet window was open."
  • 侵攻しんこうCommon
    noun, suru verb, transitive verb, intransitive verbSpecifically the advance of an armed force into another country or territory; a military word. Use it for armies marching in, not for trespassing or abstract encroachment.
  • 侵略しんりゃくJLPT N1approx.Common
    noun, suru verb, transitive verb, intransitive verbThe invasion of one country by another, viewed as an act of aggression; the word of history and politics. It carries a strong sense of condemning the invading side.
    ヒトラーは1939年ねんにポーランドを侵略しんりゃくした。↗
    Hitler invaded Poland in 1939.
  • 襲来しゅうらいCommon
    noun, suru verb, intransitive verbFrames an invasion as an attack descending on you: an enemy force or a calamity arriving at one's place. Seldom the neutral word for one country's invasion of another — that is 侵略 or 侵攻.
  • 侵害しんがいCommon
    noun, suru verb, transitive verbNot a physical invasion at all: it means infringing or violating rights, interests, or privacy. English 'invasion' as in 'invasion of privacy' corresponds to this word, not to the military terms.
    彼かれは他人たにんの私事しじを侵害しんがいする。↗
    He invades the privacy of others.

Use 侵略 for a country's invasion as an act of aggression, 侵攻 for a military advance into territory, 侵入 for intruding into a place, 襲来 for an attack or calamity arriving, and 侵害 for infringing rights.
