How to say "meaningful" in Japanese

Choosing the right word
  • 有意義ゆういぎCommon
    na-adjectiveThe common everyday word for 'meaningful' in the sense of worthwhile or rewarding — meaningful work, experiences, or time. When you mean something valuable and fulfilling rather than suggestive, this is the default choice.
    大学だいがくでの生活せいかつは有意義ゆういぎである。↗
    The life in the university is significant.
  • 有意ゆうい
    na-adjective, no-adjectiveLess common, and in practice chiefly a term of statistics and other technical fields, where it means 'significant' in the sense of statistically significant. Seldom the word you want for everyday 'meaningful'.
  • 意味ありげいみありげ
    expression, na-adjectiveDescribes a look, smile, tone, or remark that seems to carry an unstated meaning — suggestive or telling rather than plainly significant. This is what you reach for with a 'meaningful glance' or 'meaningful pause'.
  • na-adjectiveSuggestive with an air of mystery: it describes someone or something that looks as if there is an untold story behind it, often with a faintly suspicious air. It is usually written in kana alone.
  • 意味深長いみしんちょう
    na-adjective, nounPregnant with significance: a four-character idiom for remarks, works, or events with profound, often hidden meaning that rewards reflection. It points to depth rather than mere hinting.
    彼女かのじょの態度たいどは意味いみ深長しんちょうだった。↗
    She gave me a meaningful look.

For worthwhile, rewarding 'meaningful' use 有意義; for technical 'significant' use 有意; for looks or remarks hinting at hidden meaning use 「意味ありげ」 or, with an air of mystery, 「いわくありげ」; 意味深長 expresses profound, pregnant significance.
