ふと

• Reading: ふと
• Romaji: futo
• Pronunciation: /ɸɯ.to/

Meaning

Suddenly; by chance; unexpectedly. Describes something happening without planning or intention.

An adverb describing unintentional or spontaneous moments — a thought crossing your mind, accidentally glancing at something, or suddenly noticing. Common patterns: ふと思う (suddenly think), ふと気づく (happen to notice), ふと見ると (when I happened to look). Softer than 突然 (totsuzen, abruptly), suggesting a gentle, quiet moment of realisation rather than shock.

Examples

1. 電車の中でふと窓の外を見た。 I happened to look out the window on the train.
2. ふと昔の友達のことを思い出した。 I suddenly remembered an old friend.
3. 歩いていたらふと甘い匂いがした。 While walking, I caught a whiff of something sweet.

Origin & History

Historically written as 不図, a compound of 不 (fu, not) and 図 (to, plan/intention) — literally 'unplanned.' The hiragana form ふと is now standard, as the kanji writing has become archaic.
