Miyako Bay

The mouth of the bay, which opens to the north, is located almost in the center of the Sanriku Coast in central-eastern Iwate Prefecture. It lies in the sea area south of a line connecting Cape Hei at the northern tip of the Omoe Peninsula with Cape Tategasaki on the opposite shore, and the mouth of the bay is about 4 kilometers wide and 10 kilometers north to south. The Hei River flows into the center of the west coast, and the area around the mouth of the river forms Miyako Port. The Tsugaruishi River also flows into the head of the bay in the south. The water is about 60 meters deep at the mouth of the bay and about 20 meters deep in the center. In addition to fixed net fishing, the bay is used for aquaculture of seaweed, oysters, wakame seaweed, scallops, and other fish. Reclamation work for port construction has progressed on the right bank of the Hei River, and the only swimming beach left is the Fujinokawa River.

岩手県中東部、三陸海岸のほぼ中央にある、北に開いた湾口。重茂(おもえ)半島北端の閉伊(へい)崎と対岸の館(たて)ヶ崎を結ぶ線から南の海域で、湾口の幅約4キロメートル、南北約10キロメートル。西岸の中央に閉伊川が注ぎ、河口一帯は宮古港となっている。また南部の湾頭に津軽石川が注いでいる。湾口部の水深は約60メートル、中央部で約20メートル。湾内では定置網漁業のほか、ノリ、カキ、ワカメ、ホタテなどの養殖漁業が行われる。閉伊川右岸では港湾建設の埋立てが進み、海水浴場も藤ノ川を残すだけになった。
