How to say "remarkable" in Japanese

Choosing the right word
  • 顕著けんちょCommon
    na-adjective, nounCovers 'remarkable' in the sense of clearly evident: a difference, change, or effect so plain that it cannot be missed, the kind of wording found in research findings or reports.
    高熱こうねつがこの病気びょうきの顕著けんちょな症状しょうじょうだ。↗
    High fever is a prominent symptom of this disease.
  • 著しいいちじるしいJLPT N1approx.Common
    i-adjectiveThe broadest choice: 'remarkable' change, growth, or difference that is strikingly large in degree, and it fits both favorable and unfavorable developments, from rapid progress to marked decline.
    科学かがくは著いちじるしく進歩しんぽした。↗
    Science has made remarkable progress.
  • 格段かくだんCommon
    no-adjective, na-adjectiveIts 'remarkable' sense is narrow: a difference or improvement that is dramatically greater than before. It is not a general adjective for remarkable things, so it seldom fits outside such comparisons.
    それは以前いぜんに比くらべて格段かくだんに進歩しんぽした。↗
    It has greatly improved compared with what it was.
  • 目覚ましいめざましいJLPT N1approx.Common
    i-adjective'Remarkable' with an admiring tone: strikingly good progress, achievement, or activity that impresses the observer. It praises, so it does not suit neutral or negative changes.
    Japan achieved a remarkable development in industrial technology after the war.
  • 非凡ひぼんCommon
    na-adjective, nounHere 'remarkable' means extraordinary rather than striking: people or abilities that are out of the ordinary. It is not the word for remarkable changes, results, or differences.
    彼女かのじょは非凡ひぼんな音楽おんがくの才能さいのうを持もっている。↗
    She has an extraordinary ability in music.

Use 「著しい」 for strikingly large change or degree, 顕著 for clearly evident differences, 格段 for dramatic improvement or difference, 「目覚ましい」 for impressively good achievement, and 非凡 only for extraordinary people or talent.
