In most Japanese restaurants you will immediately be presented with a hot (or cool in the summer) wet towel. Oshibori should be used to wipe the hands clean before dining. Some also use the towels to wipe their faces. This is a great way to refresh yourself, especially if you’ve been walking through the city.
When the oshibori is presented, unfold the towel, use, and then fold and replace the used towel in the basket that accompanied the towel.
