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.
He was staring vacantly out the window.
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.
His vacant eyes were striking.
A more literary or formal term meaning 'vacantly', 'dazedly', or 'in a daze'. Often implies shock or bewilderment.
He stood there vacantly, stunned.
To describe doing something while not really thinking about it, often due to distraction or daydreaming.
To describe looking at nothing in particular, often with a fixed, unfocused gaze.
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.
He was listening vacantly, with his mind elsewhere.
She sat with a vacant, far-off look in her eyes.
