おは

• Reading: おは
• Romaji: oha
• Pronunciation: /o.ha/

Meaning

A super-short texting abbreviation of おはよう, meaning 'morning' or 'mornin'' — the laziest possible good morning.

おは is おはよう stripped down to its bare minimum — just two syllables fired off in a text or chat. It is the quintessential morning greeting for people too sleepy or too busy to type the full word. It is most common in LINE messages, Twitter/X posts, and group chats. Despite its extreme brevity, it carries warmth because its casualness implies closeness with the recipient.

Examples

1. おは〜、今日何するの？ Mornin'~, what are you up to today?
2. おは！昨日めっちゃ寝た。 Morning! I slept so much last night.
3. おは、もう起きた？ Mornin', you up yet?
