In Japanese, you say "hello" as:
こんにちは (Konnichiwa)
- Pronunciation: kon-nee-chee-wah
- Usage: Commonly used during the daytime as a greeting, similar to "hello" or "good afternoon."
If you want to greet someone in the morning, you can say:
おはようございます (Ohayou gozaimasu)
- Meaning: Good morning (polite)
For a more casual hello, especially among friends, you can simply say:
やあ (Yā) or もしもし (Moshi moshi) - the latter is used when answering the
phone.
