How to say "wonderful" in Japanese

• 素晴らしいすばらしいJLPT N4approx.Common
  i-adjectiveThe all-purpose word for 'wonderful' as outstanding quality or effect: splendid, magnificent, amazing. Reach for it to praise anything that impresses you — a view, a performance, a job well done.
  その日ひは実じつにすばらしい日ひだった。↗

  It was a really beautiful day.
• 結構けっこうJLPT N5approx.Common
  na-adjectiveSeldom the word you want for 'wonderful': it normally means 'quite, considerably' or works as a polite 'that's fine, no thank you'. Its adjectival sense is closer to 'fine, nice' than to enthusiastic praise.
  好奇心こうきしんがお旺盛おうせいなのは大変たいへんに結構けっこうなことである。↗

  A healthy curiosity is truly a fine thing.
• 最高さいこうJLPT N3approx.Common
  no-adjective, na-adjectiveCovers 'wonderful' as 'the best': superlative, enthusiastic approval. Typical when reacting to something you loved — a meal, a trip, a match — where an English speaker might say 'that was the best!'
  彼かれは現存げんそんする最高さいこうの芸術家げいじゅつかである。↗

  He is the greatest living artist.
• 不思議ふしぎJLPT N3approx.Common
  na-adjective, nounHere 'wonderful' means wondrous rather than excellent: strange, marvelous, incredible, defying explanation. Use it for mysteries and magical or uncanny things; it is the 'wonder' in 'wonderful', not a word of praise for quality.
  この刀かたなには不思議ふしぎないわれがある。↗

  This sword has a strange history.
• 素敵すてきJLPT N3approx.Common
  na-adjectiveCovers 'wonderful' in the sense of 'lovely' or 'charming': personal appreciation of something attractive or delightful — a dress, a room, a kind gesture. It praises charm and appeal rather than excellence or achievement.
  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.

Use 「素晴らしい」 for general excellence, 素敵 for lovely or charming appeal, 最高 for 'the best' enthusiasm, and 不思議 for the wondrous or mysterious; 結構 normally means 'quite' or 'that's fine' and is seldom the word you want.
