Mutsu Bay - Mutsuwan

A bay in central Aomori Prefecture, surrounded by the Shimokita Peninsula and the Tsugaru Peninsula. It is connected to the Tsugaru Strait by the Hiradate Strait in the northwest. The southern part of the bay is divided by the Natsudomari Peninsula into Noheji Bay on the east and Aomori Bay on the west. Ominato Bay is also located in the northeast corner. The bay has an area of ​​about 1,500 square kilometers, and a coastline of about 250 kilometers. The average depth is about 38 meters. The seabed in the center is flat, at a depth of 40 to 50 meters, and there are steep cliffs off Cape Yakeyama on the Shimokita Peninsula and on the west side of the Natsudomari Peninsula. Sardines and cod were once fished in the bay, but scallop farming has become popular since the 1960s. In addition to scallops, wakame seaweed, nori seaweed, oysters, etc. are also cultivated. It was once a route for the Seikan Ferry, but was discontinued in 1988. There is a ferry boat route connecting Noheji and Hakodate.
