How to say "infringement" in Japanese

Choosing the right word
  • 侵害しんがいCommon
    noun, suru verb, transitive verbThe default word for infringement of rights and interests — copyright, patents, privacy and the like; the nuance is encroaching on what belongs to someone else.
    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.
  • 抵触ていしょくCommon
    noun, suru verb, intransitive verbInfringement of a law or treaty: an act that comes into conflict with the provision, running afoul of it; the nuance is clashing with the rule rather than violating a right.
  • 侵犯しんぱんCommon
    noun, suru verb, transitive verbViolation or invasion of foreign territory, rights and the like, with a strong sense of intrusion; for ordinary infringement of someone's rights, 侵害 is usually the word you want.
    民間機みんかんきが軍事的ぐんじてき領域りょういきを侵犯しんぱんしたとのことです。↗
    A commercial airplane allegedly violated military airspace.
  • 違反いはんJLPT N3approx.Common
    noun, suru verb, intransitive verbReally 'violation' or 'breach' — breaking a rule, law or regulation; for infringement of rights in the sense of encroaching on them this is not the word you want.
    Despite their own scandals, the police continue to make arrests as though nothing had happened at all.
  • 反則はんそくCommon
    noun, suru verb, intransitive verbA breach or infraction of rules or regulations — the word for a foul or rule violation in a game or sport; like 違反, it is about rule-breaking, not infringement of rights.

Use 侵害 for infringement of rights or interests; 抵触 for acts that conflict with a law or treaty; 侵犯 for invasion of territory or rights; 違反 and 反則 are really violations or breaches of rules, not rights-infringement.
