Cups used for drinking a special rice wine, called Toso in Japan

A rice wine cup (Chinese: 酒杯, Japanese: 盃) is a vessel for drinking rice wine. In East Asia (China , Japan and Korea), the traditional rice wine cups are usually round and shallow, in contrast to the deeper wine glasses of Western culture.

Rice wine cups can be made of stone, porcelain, metal or wood. Wooden cups often use lacquerware, and can be floated in water during winding stream parties.
