• Synonym有用ゆうようNeutralMeans useful, with the focus on whether something can be put to use; typically used to evaluate tools and information.
• Synonym意義深いいぎぶかいWrittenWritten/formal. Suggests far-reaching significance and carries a more solemn tone than 「有意義」; used of experiences, research, discussions and the like.
• Synonym価値あるかちあるNeutralMeans valuable. An expository-sounding phrasing — close to 「有意義」 in sense but noticeably stiffer.
• Related重要じゅうようNeutralMeans important, stressing sheer weight; unlike 「有意義」 it does not necessarily imply a sense of gain.
• Related大切たいせつNeutralMeans important or precious, colored by a feeling of cherishing something, as in 「大切な人」.
• Related肝心かんじんNeutralMeans crucial or vital, zeroing in on the core point, as in 「肝心な点」.
• Related役立つやくだつNeutralA verb meaning to be useful or to serve a purpose; common in speech, with the stress on practical results.
• Related実用的じつようてきNeutralMeans practical, stressing real-world application; it says nothing about how meaningful something is.
• Related重宝ちょうほうNeutralMeans handy and convenient, as in 「重宝する」; the emphasis is on practical value in use.
• RelatedいいNeutralSimply means good — the broadest word of all, giving a vague overall verdict rather than commenting on meaning.
• RelatedグッドCasualA loanword meaning good; breezy and colloquial, with a vague overall evaluation.
• Related便利べんりNeutralMeans convenient, stressing that something saves trouble and effort; it does not address whether something is meaningful.
• Related有意ゆういWrittenWritten/formal. Means meaningful, but also statistically significant or intentional — a technical, specialist flavor.
• Related助けになるたすけになるNeutralA set phrase meaning to be helpful; colloquial, and centered on being useful to people.
• Antonym無意味むいみNeutralMeans utterly meaningless — the direct opposite of 「有意義」.
• Antonym無駄むだNeutralMeans wasted or futile — the opposite of 「有意義」 in its rewarding, gainful sense.

Use 「有意義」 for time or experiences that feel fulfilling and rewarding, as in 「有意義な時間を過ごす」. When the point is real benefit, say 「有益」; when something can be put to use, 「役立つ」; for sheer importance, 「重要」. 「意義深い」 is a weightier written option, 「有用」 fits tools and information, 「便利」 is about convenience, and 「大切」 and 「肝心」 stress cherishing and critical importance. The opposites are 「無意味」 and 「無駄」.
