Translation guide
Describes doing something with an empty, unfocused, or absent-minded expression or manner. In Japanese, this is expressed through adverbs, mimetic words, and descriptive phrases that convey blankness, absent-mindedness, or staring into space.
To describe looking or acting without any clear thought or emotion, often with a blank face.
A mimetic adverb meaning 'vacantly', 'absently', or 'blankly'. Very common and natural for describing a vacant expression or state of mind.
彼は窓の外をぼんやりと眺めていた。
He was staring vacantly out the window.
彼女はぼんやりとした表情で座っていた。
She sat with a vacant expression.
A na-adjective meaning 'vacant', 'hollow', or 'blank'. Often used to describe eyes or a gaze that lacks focus or emotion.
彼のうつろな目が印象的だった。
His vacant eyes were striking.
A more literary or formal term meaning 'vacantly', 'dazedly', or 'in a daze'. Often implies shock or bewilderment.
彼は茫然と立ち尽くした。
He stood there vacantly, stunned.
To describe doing something while not really thinking about it, often due to distraction or daydreaming.
Also covers absent-mindedness. Can be used for actions done without focus.
ぼんやりしていて電車を乗り過ごした。
I was spacing out and missed my train stop.
A noun meaning 'absent-mindedness' or 'having one's head in the clouds'. Often used with で or の.
To describe looking at nothing in particular, often with a fixed, unfocused gaze.
Literally 'to stare into the void/empty space'. A natural way to describe staring vacantly.
彼は虚空を見つめて何かを考えていた。
He was staring vacantly into space, thinking about something.
Describes eyes that look as if gazing into the distance, often vacantly.
彼女は遠くを見るような目で座っていた。
She sat with a vacant, far-off look in her eyes.
ぼんやり is the most common and versatile for 'vacantly'. It can describe both a state of mind and a facial expression. うつろ specifically describes a hollow or empty look, especially in the eyes. 茫然 is stronger, often implying shock or being stunned into a vacant state, and is more literary.
There is no single Japanese adverb that perfectly matches all uses of 'vacantly'. Using ぼんやり is the safest default, but consider the specific nuance: blank expression, absent-mindedness, or staring into space.
彼は上の空で話を聞いていた。
He was listening vacantly, with his mind elsewhere.
