How to say "fantastic" in Japanese

Choosing the right word
  • na-adjectiveThe direct loanword, used much as in English for enthusiastic approval: 'That's fantastic!' It covers the excited 'wonderful, great' sense rather than 'odd' or 'bizarre'.
  • 奇想天外きそうてんがいCommon
    na-adjective, no-adjectiveCovers 'fantastic' in the sense of wildly imaginative and bizarre: outlandish ideas, plots, or schemes so unconventional they seem unbelievable. It describes the strangeness, not the excellence, of something.
    このミステリーのトリックは、奇想天外きそうてんがいだ。↗
    This mystery has a plot twist that's completely novel.
  • 珍妙ちんみょうCommon
    na-adjective, nounCorresponds to the 'queer, odd' side of 'fantastic', not the approving one: it describes something strange or peculiar, often amusingly or critically so. It is seldom what you want for 'wonderful'.
  • 素敵すてきJLPT N3approx.Common
    na-adjectiveCovers the warm, approving sense: something lovely, charming, or enchanting that you find delightful. Typical when complimenting clothes, a person, a place, or an evening.
    あなた達たちは本当ほんとうに素敵すてきなお客きゃくだ。↗
    You're such a lovely audience.
  • 憎いにくいJLPT N2approx.Common
    i-adjectiveLiterally 'hateful', but here it works as admiring praise: something done so skillfully or cleverly that it commands grudging, half-envious admiration — 'fantastic' in the sense of 'brilliant, admirable'.

Use 「ファンタスティック」 for enthusiastic approval, 素敵 for charming loveliness, 「憎い」 for admiring 'brilliant!' praise, 奇想天外 for wildly bizarre ideas, and 珍妙 only for odd, queer strangeness.
