How to say "moment" in Japanese

Choosing the right word
  • 時ときJLPT N5approx.Common
    nounCovers 'moment' as a point in time — 'at that moment', 'the moment when something happened'. Its basic meaning is time or occasion, so for a fleeting instant another word usually fits better.
    12才さいの時とき彼かれは声変こえがわりした。↗
    His voice broke when he was twelve.
  • 瞬間しゅんかんJLPT N3approx.Common
    nounThe straightforward word for a moment or instant: a very short stretch of time, as when something happens. Reach for this when you simply mean a brief point in time.
    この瞬間しゅんかんは歴史れきしに記録きろくされるだろう。↗
    This moment will be recorded in history.
  • 一瞬いっしゅんJLPT N3approx.Common
    noun, adverbAn instant so brief it barely registers — 'for an instant', 'in a flash'. Use it when the emphasis falls on just how short the moment is.
    それは私にとってはらはらする一瞬いっしゅんだった。↗
    It was a nervous moment for me.
  • nounHere 'moment' means a short while — a brief stretch of time experienced or spent, not a split second. It is usually written in kana alone rather than in kanji.
    私達わたしたちは海岸かいがんですばらしいひとときを過すごした。↗
    We had a glorious time at the seaside.
  • 刹那せつなCommon
    noun, adverbAn instant treated as vanishingly brief; the word carries a poetic, weighty tone compared with 瞬間, and for an ordinary 'moment' 瞬間 is usually the safer choice.

Use 瞬間 for a neutral brief instant, 一瞬 when stressing brevity, 時 for 'the moment when' as a point in time, 「ひととき」 for a short while, and 刹那 for a poetic, vanishingly brief instant.
