How to say "cruel" in Japanese

Choosing the right word
  • ひどいJLPT N4approx.Common
    i-adjectiveThe broadest choice: cruel or heartless words and treatment, and by extension anything harsh or simply terrible. When you mean a plain 'that's cruel' in ordinary situations, this is the word you reach for.
  • 残酷ざんこくJLPT N1approx.Common
    na-adjective, nounThe core word for cruelty itself: brutal, ruthless, merciless acts or treatment, from cruel punishment to a cruel twist of fate; stronger and more pointed than ひどい.
    The monster's smile was cruel.
  • 無残むざんCommon
    na-adjective, nounCruel in the sense of atrocious: merciless deeds or outcomes that leave someone in a miserable state, as in a brutal end or crushing defeat; often stresses the wretched result.
  • 残虐ざんぎゃくCommon
    na-adjective, nounThe savage, barbarous face of 'cruel': brutal violence and atrocities, cruelty whose savagery shocks. It fits accounts of barbaric acts of violence, not everyday unkindness.
    警官けいかんたちはその残虐ざんぎゃくな殺人さつじん事件じけんの手掛てがかりを捜さがしている。↗
    The cops are searching for clues to the cruel murder.
  • 邪険じゃけんCommon
    na-adjective, nounCruel in the interpersonal sense: hard-hearted, harsh, unkind treatment of a person; the cruelty lies in coldness of manner, not brutality or violence. Often closer to 'heartless' than 'cruel'.

    Please don't be cold!
