"Ohayo" is the Japanese word for "good morning." It is a common greeting used when meeting someone in the morning or when starting a conversation or phone call. It is also used as a way to say "hello" to someone who has just woken up. In Japan, it is considered polite to greet others with "ohayo" as a sign of respect and good manners.
This site is all about Japan and is intended to make people aware of the beautiful country. It's also my favorite country, though I've never gotten around to traveling there.
