enkai - ‰ƒ‰ï
This is a drinking party, usually sponsored by an office or place of employment. Japanese people typically don't need much of an excuse to drink, so pretty much any organization will have these with some frequency. Usually they happen at the beginning of the year, the end of the year, when someone new starts or someone leaves, or pretty much any other time that someone can think of any flimsy excuse. Usually these events have a set price and are both tabehodai and nomihodai.
