description Mutsu Bay Overview

Mutsu Bay is a nearly enclosed inlet located on the northern coast of Honshu in Aomori Prefecture, Japan. It is formed by the curves of the Shimokita and Tsugaru peninsulas, providing calm waters that are highly conducive to aquaculture. The bay is a major production center for scallops and oysters, which are central to the local economy. Coastal towns around the bay serve as ports for the local fishing fleet.
