Lake Shinji, the brackish lake on the edge of Matsue, is Japan’s leading source of yamato-shijimi, small freshwater clams that are the star of the region’s most beloved dish: shijimi miso soup. The tiny black clams give a deep, savoury broth rich in umami, and the soup is a Matsue staple eaten especially at breakfast — and famous throughout Japan as a folk remedy for a hangover, thanks to the ornithine the clams contain. The clams are gathered by hand-raking from small boats on the lake, a sight in itself, and the soup appears everywhere from ryokan breakfasts to lakeside restaurants.

Tips
Have it at breakfast, which is the traditional and best time — many Matsue ryokan serve it as part of the morning meal, and that’s the authentic way to try it. Watch for the clam-raking boats out on Lake Shinji, and pair the whole thing with the lake’s famous sunset, which is itself one of Matsue’s signature sights.
