How to say "silly" in Japanese

Choosing the right word
  • 愚かおろかJLPT N1approx.Common
    na-adjectiveCovers the 'foolish, silly' sense: lacking sense or judgment. It is a serious, disapproving word for a person or act, stronger than playful teasing, as in calling a decision or remark foolish.
    そんな愚おろかなことを言ゆうな。↗
    Do not say such foolish things.
  • 浅はかあさはかCommon
    na-adjectiveMatches 'silly' only in the sense of thoughtless or short-sighted: a shallow judgment made without thinking things through, such as a hasty plan or a careless remark one regrets.
    私はあさはかにも彼かれが私を助たすけてくれるんだなあと思おもった。↗
    I foolishly imagined that he was going to help me.
  • 馬鹿らしいばからしいJLPT N2approx.Common
    i-adjectiveCovers 'silly' in the sense of absurdly not worthwhile: something so foolish that bothering with it seems pointless, like silly rules or arguments not worth taking seriously.
    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.
  • 滑稽こっけいJLPT N1approx.Common
    na-adjective, nounCovers 'silly' as ridiculous or laughable: behavior or appearance so absurd it makes people laugh. It suggests something comical rather than contemptible, like a silly costume or antic.
  • くだらないJLPT N2approx.Common
    i-adjectiveCovers 'silly' as trivial or nonsensical: things with no value or point, such as silly jokes, worries, or talk. Often the natural word for dismissing something as a waste of time.

'Silly' spans foolish (「愚か」), shallow-thoughtless (「浅はか」), not-worth-it absurdity (「馬鹿らしい」), laughable ridiculousness (滑稽), and pointless triviality (「くだらない」); pick by whether you mean stupid, shortsighted, absurd, comical, or worthless.
