An oshibori is a wet hand towel offered to customers in places such as restaurants or bars in Japan (and in many Japanese restaurants worldwide). Oshibori are used to clean one’s hands before eating, and have long been a common sight in Japan.
Cold oshibori are used in summer, and hot oshibori in winter.
Many places offer a disposable form of oshibori, including fast food restaurants like Kentucky Fried Chicken. These towels are all individually wrapped and pre-moistened, and some even come in different scents.
