Lifting Bowls

In Japan, it is perfectly acceptable to lift the bowl to taste soup or eat rice. Conversely, eating rice or miso soup without picking up the bowl and leaving it on the table is considered bad manners. Other small plates and bowls are also easier to eat if you lift them.

What should not be lifted are plates of grilled fish or tempura, large bowls, and plates that are too large to lift and eat.
