Translation guide
The English interjection 'haha' represents laughter. In Japanese, laughter is expressed differently depending on medium, tone, and gender. This guide covers how to convey laughter in text, speech, and online communication.
（実際に笑う、または「笑った」と言う）
haha (in speech)
Don't say 'haha' as an interjection. Just laugh or say 'I laughed'.
To express laughter in casual digital communication, such as texting, social media, or online chats.
The kanji for 'laugh', often used alone or repeated to indicate laughter, similar to 'lol'. Very common in informal online text.
Abbreviation of 笑 (warai), from the first letter of its romaji. Multiple 'w's indicate stronger laughter, like 'www' for 'lololol'. Extremely common online.
Slang for laughter, derived from the appearance of multiple 'w's looking like grass. Used similarly to 'lol' or 'haha' in very casual online contexts.
To express laughter in face-to-face conversation or voice communication.
Japanese speakers use sounds like 'はは' (haha), 'ひひ' (hihi), or 'ふふ' (fufu) to represent laughter in speech, but these are not used as interjections in the same way as English 'haha'. Instead, they are often part of reported speech or storytelling.
彼は「ははは」と笑った。
He laughed, 'hahaha'.
Instead of using an interjection, it's more natural to say '笑った' (I laughed) or '笑ってる' (I'm laughing) to convey that something is funny.
それ聞いて笑っちゃった。
I heard that and laughed (haha).
To indicate laughter in formal writing, literature, or polite communication.
Means 'sound of laughter'. Used in descriptive writing rather than as an interjection.
部屋から笑い声が聞こえた。
I could hear laughter from the room.
The verb 'to laugh'. In formal contexts, describe the action rather than using onomatopoeia.
In English, 'haha' is a common interjection to express laughter. In Japanese, simply saying 'はは' (haha) aloud as a reaction is unnatural. Instead, Japanese speakers might actually laugh, say '笑った', or use other expressions like 'うける' (ukeru, 'that's funny') in casual speech.
うける！
That's hilarious! (haha)
All three are used online to indicate laughter. '笑' is the most standard and can be used by anyone. 'w' is very common and casual, often repeated. '草' is slangier and more playful, popular among younger users. In formal digital communication, avoid all three and use descriptive phrases instead.
Everyone laughed at the joke.
