How to say "incredible" in Japanese

Choosing the right word
  • すげーCommon
    interjection, expressionCovers the exclamatory 'incredible!' of amazement at something impressive or unbelievable. It is rough, casual speech, so it fits excited talk with friends rather than polite or written contexts.

    Wha? Study, reflexes, all the parameters are MAX! You've even saved money up to the limit ... Amazing.
  • 奇想天外きそうてんがいCommon
    na-adjective, no-adjectiveMatches 'incredible' only in the sense of bizarre, wildly imaginative, or off-the-wall. Use it for plots, ideas, or schemes so outlandish they defy expectation, not for general praise.

  • 不思議ふしぎJLPT N3approx.Common
