Japanese Greetings

Here are a few standard hello and goodbye phrases.  Some of them are quite casual in use, although I’ve tried to point out where that is the case.  Another quick note about the use of “genki” - although English speakers frequently use “how are you?” it’s not really that familiar to Japanese speakers and if you ask “genki?” often, then it sounds like you have a real concern for their well-being (as opposed to merely indicating that you’re mildly interested in their current mood).
