Summary

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 roughly 30-35mm and are reddish-brown while young, turning black as they mature. Their shells are glossy and have a tendency to grow concentric circles from their base, similar to Corbicula fluminea. The inside of their shells is purple when they are young and becomes white as they mature. Their reproduction is based on gonochorism.

As food
Shijimi miso soup

Shijimi and Asari (Venerupis philippinarum) are the most popular bivalvia-using miso soups in Japan, as well as soups using Tsukudani.[3]
