How to say "ambiguous" in Japanese

Choosing the right word
  • 曖昧あいまいJLPT N2approx.Common
    na-adjective, nounThe closest match for 'ambiguous' in its core sense: a statement, answer or attitude that is unclear or can be taken in more than one way, often because the speaker is being deliberately noncommittal.
    その法律ほうりつには曖昧あいまいな点てんが多おおい。↗
    That law is full of ambiguities.
  • 意味不明いみふめいCommon
    na-adjective, no-adjectiveFocuses on meaning itself being unfathomable: what someone said or wrote is cryptic, baffling or seems to make no sense, rather than merely having two possible readings.
    It is often pointed out that a vague smile is typical of the Japanese.
  • 不明ふめいJLPT N1approx.Common
    na-adjective, nounReally means 'unclear' or 'unknown' — a cause, fact or detail that cannot be determined — so it suits 'ambiguous' only loosely; it does not describe wording open to several interpretations.
  • 漠然ばくぜんJLPT N1approx.Common
    taru-adjective, adverb (with と)Covers the 'vague' side of 'ambiguous': impressions, ideas or fears that are hazy and not clearly formed. It is not the word for a phrase that carries two distinct readings.
  • あやふやJLPT N1approx.Common
    na-adjectiveA mimetic word for something not firmly settled — an answer, memory or position left indefinite, so you cannot pin it down. Fits 'ambiguous' when the emphasis is on vagueness or noncommittal wavering.
    あやふやな手てつきで一いち枚まいの紙かみを動うごかした。↗
    She fumbled with a piece of paper.

Choose 曖昧 for statements or attitudes open to more than one reading, 意味不明 for meaning you cannot work out, 不明 for facts that are unclear or unknown, 漠然 for hazy impressions, and 「あやふや」 for indefinite, noncommittal answers.
