Kimasu is a wooden sake cup found in Izakayas (casual Japanese bars serving small bites)
everywhere. It is common for regulars of an Izakaya to sign their kimasu, and leave it there so
they can drink out of their own when they visit.
*Some sake etiquette: if you’re with someone else, its good manners to pour servings for your
partner. And when someone’s pouring sake for you it’s polite to hold your sake cup up with one
hand and put your other hand under the cup. Have a sip before putting the cup back on the table.
