どーも

• Reading: どーも
• Romaji: domo
• Pronunciation: /doː.mo/

Meaning

An ultra-flexible casual greeting that can mean 'hey,' 'thanks,' 'hi,' or 'sorry' — the Swiss army knife of Japanese greetings.

どーも (elongated form of どうも) is perhaps the most versatile single word in Japanese social interaction. It can serve as a greeting (hi), thanks (thanks), apology (sorry about that), or farewell (see ya). The elongated vowel makes it feel more casual and breezy than the standard どうも. Its power lies in its vagueness — it acknowledges the other person positively without committing to a specific sentiment.

Examples

1. あ、どーも、お久しぶりです。 Oh, hey, it's been a while.
2. どーも、これどうぞ。 Hey, here you go.
3. どーも〜、また来ましたよ。 Hey there~, I'm back again.

Do Say

• あ、どーも、元気ですか？ (Oh hey, how are you?)

Don't Say

Common Mistakes

• Thinking どーも is impolite — it is casual but not rude in most everyday situations
• Not understanding which meaning is intended — context and tone are key

Origin & History

Casual elongated form of どうも, which derives from a classical adverb meaning 'in any way' or 'by all means.' Over time it became a catch-all social acknowledgment. The vowel elongation (どうも → どーも) adds casualness and is standard in speech and texting.
