Choosing the right word
  • 変へんJLPT N4approx.Common

  • 不思議ふしぎJLPT N3approx.Common
    na-adjective, nounTakes 'curious' toward 'mysterious, puzzling': something wondrous or hard to explain rather than merely odd. Fits a curious phenomenon or coincidence that leaves you wondering how it could be.

    This sword has a strange history.
  • 珍しいめずらしいJLPT N4approx.Common
    i-adjectiveRenders 'curious' as 'unusual': the emphasis falls on rarity and novelty rather than strangeness. Choose it for a curious sight or object — something you have seldom seen before.

    This is a strange kind of fish.
  • 妙みょうJLPT N3approx.Common
    na-adjective, nounCovers 'curious' as 'odd' with a vague, hard-to-place quality: something feels slightly off, though you cannot say just why. Suits a curious feeling, taste, or atmosphere.
    彼かれは自分じぶんの妙みょうな行動こうどうについて明確めいかくに説明せつめいはしなかった。↗
    He offered no specific explanation for his strange behavior.
  • 奇妙きみょうJLPT N3approx.Common
    na-adjective, nounCovers 'curious' as 'peculiar, queer': strangeness pronounced enough to make you puzzle over it. Typical contexts include a curious shape, a peculiar incident, or an event that seems decidedly odd.
    これはとても奇妙きみょうな手紙てがみです。↗
    This is a very strange letter.

All five render the 'strange, odd' side of curious, not the 'eager to know' sense: choose 変 for plain weirdness, 妙 for something vaguely off, 奇妙 for pronounced peculiarity, 不思議 for the mysterious, 「珍しい」 for the unusual.
