笑う

• Reading: わらう
• Romaji: warau
• Kanji breakdown: 笑 (laugh/smile) + う (verb suffix) → to laugh
• Pronunciation: /wa.ɾa.ɯ/

Meaning

As a slang reaction: 'LOL' or 'I'm laughing' — used at the end of sentences or as a standalone amused response.

笑う is the standard Japanese verb meaning 'to laugh,' but in internet and texting culture it doubles as a reaction marker. Written as (笑) after a sentence, abbreviated to 笑 alone, or shortened to 'w,' it is the most universal Japanese laugh expression. Unlike 草 or わろた which are strictly internet slang, 笑う in parentheses (笑) bridges casual and semi-formal written communication, appearing even in some magazine articles and light business messages.

Examples

1. 寝坊して逆方向の電車乗っちゃった（笑）。 I overslept and got on the train going the wrong direction (lol).
2. あの番組の司会者面白すぎて笑う。 The host of that show is so funny I can't stop laughing.
3. 自分で作ったお弁当が崩壊してて笑うしかない。 My homemade bento completely fell apart and all I can do is laugh.
