How to say "oppose" in Japanese

Choosing the right word
  • 立ち向かうたちむかうCommon
    godan verb, intransitive verbCovers facing or fighting against something difficult — an opponent, hardship, or crisis — rather than disobeying a person. Use it when you confront a challenge head-on with determination.
    彼女かのじょは自分じぶんの運命うんめいに立ち向たちむかう覚悟かくごができていた。↗
    She was ready to face her fate.
  • 逆らうさからうJLPT N3approx.Common
    godan verb, intransitive verbThe general word for going against a person, rule, or current: to oppose or disobey someone's will or authority. Use it when defying orders, social expectations, or the flow of things.
    彼かれは世よの風潮ふうちょうに逆さからう。↗
    He is swimming against the tide.
  • 阻むはばむJLPT N1approx.Common
    godan verb, transitive verbThis one is really about blocking, stopping, or preventing an action rather than opposing a person or idea. It is seldom the word you want for 'oppose' in the sense of being against something.
    彼かれらは大おおきな川かわに前進ぜんしんを阻はばまれた。↗
    Their progress was stopped by a wide river.
  • 歯向かうはむかうCommon
    godan verb, intransitive verbCovers rising against or turning on someone, often with an image of talking back or resisting a superior or attacker. It suggests open, often defiant resistance from a weaker party.
    ウサギでさえ、いじめられて片隅かたすみに追おいつめられると、刃向はむかってくるだろう。↗
    Even a rabbit, if badgered into a corner, will fight back.
  • 楯突くたてつくCommon
    godan verb, intransitive verbCovers defying, disobeying, or rebelling against someone above you, such as a parent, boss, or lord. It implies bold opposition to a person of higher standing and would be overkill for ordinary disagreement.
    あの人ひとにたてつかない方ほうがいいよ。↗
    You're better off not getting in his way!

Use 「逆らう」 for going against someone's will or authority, 「楯突く」 for defying a superior, 「歯向かう」 for resisting or turning on someone, 「立ち向かう」 for confronting a challenge head-on, and 「阻む」 mainly for blocking or preventing an action.
