ふと (futo)
ふと — suddenly, on an impulse
Pattern
-

Meaning and use
ふと describes something that happens suddenly and without a plan: ふと思い出す (suddenly recall), ふと気づく (notice), ふと見ると (when I happened to look). It fits near-unconscious actions like recalling, noticing and glancing.
Compared with 突然
突然 is for abrupt events; ふと is for a thought or small action that arises unexpectedly. It is not used with deliberate actions such as studying or shopping.

Common mistakes
- Do not use it with deliberate actions: ふと勉強した sounds wrong.
- It is not the same as 突然. For big events such as an earthquake, use 突然.
