Etiquette in Japan - Greetings

Greetings

Greetings are considered to be of extreme importance in Japanese culture. Students in elementary and secondary schools are often admonished to deliver greetings with energy and vigor. A lazy greeting is regarded with the type of disdain that would accompany a limp handshake in parts of the West.

The most common greetings are ohayō gozaimasu (おはようございます?) or "good morning", used until about 11am but may be used at any time of day if it is the first occasion that day the two people have met; konnichiwa (こんにちは?) which is roughly equivalent to "good day" or "good afternoon" and is used until late afternoon; konbanwa (今晩は?) or "good evening"; and oyasumi nasai (お休みなさい?) or "good night". Different forms of these greetings may be used depending on the relative social statuses of the speaker and the listener.
