Oshibori
A wet hot or cold towel provided to clean your hands before eating.
Rooted in Japan's hospitality ('Omotenashi') to comfort travelers, these towels are served piping hot in winter and refreshingly cold in summer.
Use it strictly to clean your hands. Using a high-quality cotton cloth Oshibori to wipe your face or clean spilled food on the table is generally considered bad etiquette.
