How to say "violation" in Japanese

• 違反いはんJLPT N3approx.Common
  noun, suru verb, intransitive verbThe general word for violation: breaking a law, rule, or regulation, or breaching an agreement. When English 'violation' simply means something was done against the rules, this is usually the word.
  相あい次つぐ不祥事ふしょうじにも関かかわらず、警察けいさつはオメオメ違反いはん切符きっぷを切きっている。↗

  Despite their own scandals, the police continue to make arrests as though nothing had happened at all.
• 侵害しんがいCommon
  noun, suru verb, transitive verbViolation in the sense of infringement: encroaching on or invading someone's rights or interests rather than breaking a rule. The natural choice where English says 'infringement', as of rights.
  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.
• 侵犯しんぱんCommon
  noun, suru verb, transitive verbViolation confined to foreign territory, rights, and the like — essentially 'invasion' or 'infringement' in that narrow sense. For everyday rule-breaking it is seldom the word you want; 違反 or 侵害 fits better.
  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.
• 反則はんそくCommon
  noun, suru verb, intransitive verbA violation or infraction of a specific rule or regulation, as in sports or traffic contexts. Choose it when English would say 'infraction' rather than a general violation.

Use 違反 as the general word for breaking rules or laws, 侵害 for infringing rights or interests, 反則 for infractions of specific rules, and 侵犯 for the narrower violation of territory or rights.
