Lake Shinji

Lake Shinji is a lake that stretches across Matsue and Izumo cities in Shimane Prefecture. It is one of Shimane’s leading tourist attractions, renowned for its beautiful scenery—among the finest in Japan—and abundant fishery resources. Extending west of central Matsue, the lake covers approximately 79.3 square kilometers and is known as Japan’s seventh-largest lake. The seasonal landscapes reflected on its surface are breathtaking, and the lake has been selected as one of the “100 Scenic Views of Japan.” It is particularly famous throughout the country for its spectacular sunsets.

Lake Shinji is a brackish lake where seawater and freshwater mix, creating a rich natural environment and unique ecosystem. Its beautiful scenery, plentiful seafood, lakeside hot springs, and various tourist facilities come together to make it one of Shimane Prefecture’s most popular destinations.

## Features of Lake Shinji

Lake Shinji is a natural lake located downstream in the Hii River system in eastern Shimane Prefecture. It is connected to Lake Nakaumi through the Ohashi River, and further linked to the Sea of Japan via the Sakai Channel.

Because seawater flows into the lake, its salinity is approximately one-tenth that of seawater, making it a brackish lake where freshwater and seawater intermingle. This unique environment supports a rich ecosystem inhabited by both freshwater and marine fish.

The lake has a circumference of approximately 45 kilometers. Its average depth is about 4.5 meters, while even its deepest point is only around 6 meters, making it a relatively shallow lake. As a result, the lake has a broad, open surface that beautifully reflects the sky and sunsets.

In 2005, Lake Shinji and Lake Nakaumi were jointly designated as Ramsar Convention wetlands. They are internationally recognized as important habitats for waterfowl and aquatic life.

## One of Japan’s Finest Sunset Spots

Lake Shinji’s greatest attraction is its beautiful evening scenery.

The sunsets viewed from the eastern shore on the Matsue side are especially famous, and the lake has been selected as one of the “100 Best Sunset Views in Japan.” In the evening, the surface of the lake changes from orange to red, creating a fantastic landscape in which the sky and lake appear to merge.

The most iconic feature is Yomegashima, the lake’s only island. The silhouette of Yomegashima illuminated by the setting sun is cherished as one of the signature views of Lake Shinji.

The sunset spectacle begins approximately 30 minutes before sunset and is truly breathtaking, attracting many tourists and photography enthusiasts. Because the scenery takes on a different appearance every day depending on the season and weather, visitors can experience something new each time they return.

## The Seven Delicacies of Lake Shinji

Lake Shinji is also a treasure trove of abundant fishery resources.

Among its most famous products are seven types of fish and seafood collectively known as the “Seven Delicacies of Lake Shinji”:

- Japanese sea bass
- Moroge shrimp (Japanese greasyback shrimp)
- Eel
- Amasagi (a local name for smelt)
- Freshwater clams (Asian clams)
- Carp
- Icefish

These have long been enjoyed as representative delicacies of Matsue. The first syllables of their Japanese names form the phrase “Sumoashikoshi,” which is also known locally as a mnemonic for remembering them.

## Freshwater Clams from Lake Shinji

One of Lake Shinji’s most famous local specialties is the Asian clam.

The Asian clams harvested from Lake Shinji rank among the most abundant in Japan and are well known as one of the lake’s signature products. Large and rich in flavor, they are commonly enjoyed in miso soup and clam soup.

Early in the morning, visitors can see boats lined up on the lake during clam fishing, a scene regarded as one of Lake Shinji’s characteristic seasonal traditions. Clams are also popular souvenirs, and products such as simmered clams and items made with clam extract are widely available.

## Sightseeing Boats and Sunset Cruises

Cruises on sightseeing boats are another popular activity on Lake Shinji.

One of the best-known sightseeing boats is the Hakucho, which takes passengers on an approximately one-hour tour of the lake. Sunset cruises are particularly popular. Timed to coincide with sunset, they allow passengers to enjoy the evening view from the water.

The scenery created by the red sky, the shimmering surface of the lake, and the silhouette of Yomegashima is exceptional, offering a different kind of wonder from watching the sunset on land.
