Shinji Lake is located between Matsue and Izumo districts in Shimane Prefecture. The lake is a known a‘brackish-water lake’, because it has a mixture of both fresh and seawater. Also, it is said that it was formed 10,000 years ago. The word Shinji evolved from the word ‘Swine’s pathway’. It is the 7th largest lake in Japan. Moreover, the lake is a habitat of viand fishes, both fresh water and seawater varieties. In this sense, it is also known as the number-one fare spot for Corbicula japonica. The corbiculidae shellfish plays an important role in the loch. It clarifies the water by swallowing plankton and expelling clean water. It is possible, with the present quantity of shellfish, to purify 5 times the amount of water in Shinji Lake. In winter, over 20,000 birds, including swan, goose and duck, come to the lake. The abundant fish and shellfish that depend upon the lake’s eutrophication (natural enriching with nutrient), a feature of brackish-water, become the prey of the birds. Photographers also gather around the lake to catch the mystery of nature on film.
