Lake Shinji, Ramsar wetland site in Shimane Prefecture, Japan
Lake Shinji is a brackish lake in Shimane Prefecture stretching 17 kilometers from east to west and roughly six kilometers from north to south. It connects to the Sea of Japan through Nakaumi Lagoon and forms a protected wetland with shallow shorelines and wide open water.
This body of water formed roughly 10,000 years ago when sandbanks connected the eastern and western sides of the Shimane Peninsula, which had been an island. Over the centuries, the coastal landscape transformed through natural sediment deposits into its present shape with lagoons and openings to the open sea.
Local fishers harvest clams here daily that later appear in regional soups and stews served across the prefecture. This type of shellfish has become a signature ingredient of the area's cuisine and shapes the culinary reputation of the entire region.
Pleasure boats depart near Matsue Station and offer 50-minute tours across the water. The best time to visit is early morning or late afternoon when migratory birds rest along the shores and the light softens.
The water here supports both freshwater and marine species because the salt content falls between the two extremes. Up to 240 bird species have been recorded at this body of water, making it an important stopover for migratory routes.
