Hotate Tamarei are flash-frozen scallop adductor muscles produced by Notsuke Fishery Cooperative from scallops harvested in the waters around the Notsuke Peninsula in eastern Hokkaido, Japan.

Young scallops are released onto the seabed, where they feed on plankton and grow for about four years before being harvested in the Nemuro Strait. After harvesting, the scallops are shucked, and the round muscle that closes the shell is removed and flash-frozen.

The scallops have a natural sweetness, a rich flavor, and a tender texture.
