About Deep-Seawater Purified Oysters

Deep-Seawater Purified Oysters (深層水仕込カキ, Shinsou-sui Shikomi Kaki) are oysters purified and cultivated for over 24 hours using the Nyūzen deep-seawater, drawn from a depth of 384 meters off the coast of Nyūzen.

Nyūzen Town takes advantage of its pristine water resources, including the Kurobe River fan springs, to actively promote its deep-seawater collection projects. The deep seawater is colder, more stable, cleaner, and richer in nutrients compared to surface seawater.

Compared to oysters purified with surface seawater, these oysters offer higher safety for consumption, are rich in nutrients, and carry a variety of benefits. The oysters harvested in Nyūzen are classified as rock oysters (iwagaki), known for their plump, firm texture and rich, deep flavor, making them a beloved delicacy among the locals.
