ふと

• 読み: ふと
• ローマ字: futo

意味

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.

1. 電車の中でふと窓の外を見た。
2. ふと昔の友達のことを思い出した。
3. 歩いていたらふと甘い匂いがした。

起源と歴史

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.
