Nagazarugai is found in the warm waters south of the Boso Peninsula. It inhabits sandy bottoms with many rocks. It grows to over 10 cm in height and has an oval shape. The shell has radial lines that resemble a sieve, hence its name.

Nagazarugai is a large bivalve with extremely low catch volumes, making it unavailable in the commercial market. It has a mild aroma reminiscent of Aoyagi and a sweet flavor. If you ever come across it, be sure to try it. It is such a rare shellfish that missing this opportunity may mean you never get to taste it again.
