How to say "ridiculous" in Japanese

Choosing the right word
  • 無茶むちゃJLPT N1approx.Common
    na-adjective, nounCovers 'ridiculous' in the sense of absurd and unreasonable: a demand, plan, or schedule so excessive that it defies common sense. The nuance is going too far, beyond what is reasonable.
    君きみがそれをたった一人ひとりでやろうなんてむちゃだ。↗
    You are mad to try to do it all alone.
  • 法外ほうがいCommon
    na-adjective, nounCovers 'ridiculous' chiefly of amounts — prices, fees, charges — that are exorbitant, far beyond any reasonable level. A restaurant charging a ridiculous price is the classic context.
    私はこの自転車じてんしゃを法外ほうがいに安やすく買かった。↗
    I bought this bicycle dirt-cheap.
  • おかしいJLPT N4approx.Common
    i-adjectiveThe word when 'ridiculous' means laughable or absurd enough to laugh at; also the natural exclamation — 'that's ridiculous!' — at something you find absurd.
    君きみのジョークは何度なんど聞きいてもおかしい。↗
    Your joke is funny no matter how many times I hear it.
  • pre-noun adjectivalThe same laughable, absurd sense, in the form used directly before a noun: a ridiculous story, suggestion, or situation. Use this when 'ridiculous' modifies a noun.
    We saw a funny movie last Sunday.
  • 馬鹿らしいばからしいJLPT N2approx.Common
    i-adjectiveCovers 'ridiculous' as silly and foolish rather than outrageous; said of an effort or act so silly that it is hardly worth the trouble.
    彼女かのじょは馬鹿ばからしい質問しつもんをされていらいらした。↗
    She got rattled by the stupid question.

Choose 無茶 for the absurd-unreasonable sense, 法外 for exorbitant amounts such as prices, 「おかしい」 or 「おかしな」 for the laughable sense (the latter before nouns), and 「馬鹿らしい」 for what is merely silly or pointless.
