Ways to say it

“hi” in Japanese
Japanese Romanization Note
やっほー yahhoo casual, playful
こんにちは konnichiwa polite, neutral
おは oha slang, morning, short

やっほー (yahhoo) is light and playful. おは (oha) is short for おはよう (ohayou), "good morning", and is used only among close friends. For work or first messages, use こんにちは (konnichiwa) or お世話になっております (osewa ni natte orimasu).

Is there a formal and an informal way to say it?

Text messages to teachers, clients or older people should use polite forms ending in です (desu) or ます (masu). Emojis and stamps are common among friends, but not in business texts.

Did you know?

  • In Japanese chats, people often use a sticker instead of a written greeting, which makes the message very short.
