[1][2] Japanese basket clams settle at the mouths of rivers in brackish water.

During low tide, people are able to see them in tidal flats and collect them for food.

Their shells are glossy and have a tendency to grow concentric circles from their base, similar to Corbicula fluminea.

In Japan, the clam is usually called shijimi, though this technically refers to the Corbicula genus in general.

Shijimi and asari, (Lajonkairia lajonkairii) are two of the most common clams used in soups and tsukudani (simmered seafood).
