rice bowl
a small bowl specifically used for serving and eating rice
Watch out
The everyday word for a rice bowl is 茶碗 or ご飯茶碗, despite 茶 (tea) in the name. 飯椀 is a more specific, trade-style word; it appears mainly in tableware shops and catalogs, often paired with 汁椀 (soup bowl).
Cultural note
In Japanese households each family member often has their own rice bowl, along with their own chopsticks.
