Time-Based Greeting System

Japanese greetings are time-sensitive:

• Ohayō gozaimasu (おはようございます): "Good morning" — until ~10–11 AM
• Konnichiwa (こんにちは): "Hello/Good afternoon" — ~11 AM–5 PM
• Konbanwa (今晩は): "Good evening" — after ~5–6 PM
• Oyasuminasai (おやすみなさい): "Good night" — bedtime/parting at night

Etymology and Nuance

Literally: kon (this) + nichi (day/sun) + wa (topic particle) → "As for this day..." Originally part of longer phrases like "Konnichi wa yoi hi desu ne" ("As for today, it's a fine day, isn't it?"). The truncated form became standardized.

Related Expressions

• Konnichiwa → Moshi moshi (もしもし): Phone greeting
• Yā / Yō (やー / よー): Casual "hi" among friends
• Genki? (元気？): "How are you?" / "What's up?" (casual)

Cultural Tip

Bowing accompanies konnichiwa in formal settings: 15° (casual), 30° (standard business), 45° (deep respect/apology). Eye contact is brief; prolonged staring can feel confrontational.
