Nakaumi

Japanese: 中海 - なかうみ

A lagoon (→lagoon) surrounded by the Shimane Peninsula in northeastern Shimane Prefecture and Yumigahama in northwestern Tottori Prefecture. It is also called "Nakanoumi". It is connected to the Sea of Japan by the Sakai Channel and Lake Shinji by the Ohashi River. It is a brackish lake where seawater and freshwater mix. It occupies the eastern part of the Shinji Graben, has a circumference of 105 km, an area of 86.2 ^km2 , and a maximum depth of 8.4 m. Daikon Island and Ejima Island are located in the center, and there are ports such as Matsue (Magata), Yasugi, and Yonago along the coast. In the past, shrimp, eels, mullet, and black porgy were caught here, but today there is almost no fishing. Reclamation began in 1968, and a desalination project was planned along with reclamation, but pollution of the lake became a problem, and it was decided to reclamate it in 2000 and to cancel the desalination project in 2002. It was registered under the Ramsar Convention in 2005.
