Lake Saroma

Overview & Charm

Lake Saroma, located on the Okhotsk coast of Hokkaido, is one of Japan's largest brackish lakes with an area of approximately 152 square kilometers. It is the largest lake in Hokkaido and ranks as the third largest in Japan after Lake Biwa and Lake Kasumigaura. The lake is characterized by its unique topography, separated from the Sea of Okhotsk by a long sand spit. The water salinity is close to that of the sea, giving it a dual nature of both lake and ocean. A highlight of the area is the panoramic view from the observatory at the summit of Mt. Horaiva, where you can gaze upon the vast, shimmering expanse known as 'Saroma Blue.'

History & Cultural Background

The history of Lake Saroma is ancient, with its name believed to derive from the Ainu language 'Sar-oma-pe' (river where reeds grow). There was a time when the lake was part of the sea before the sand spit formed. A significant historical event occurred in the late 1920s regarding the opening of the lake mouth. Previously, the mouth was located near the eastern end at 'Tofutsu,' creating an unstable environment that changed with the seasons. However, following dredging work in 1929, a permanent, wider opening was formed near Sanriban on the western side. This change shaped the current water quality and ecosystem. The region also holds archaeological value, with remains tracing back from the Jomon period through the Okhotsk culture to the Ainu culture.

Main Attractions

The greatest highlight of Lake Saroma is the scenery crafted by nature. First, the 'Saroma Lake Observatory' at the top of Mt. Horaiva offers a breathtaking view of the vast lake surface and its changing colors. Another must-visit is the 'Wakka Primeval Flower Garden' on the eastern side of the lake, a precious repository of flora designated as a Hokkaido Heritage site. In autumn, the community of Suaeda media (glasswort) turns a striking red, creating a unique and beautiful landscape. The long sand spit along the lakeshore is also a masterpiece of natural formation that attracts many visitors. Additionally, near the fishing ports, you can observe the seasonal movements of various marine resources.

Best Seasons & Timing

The best time to visit Lake Saroma is from May to September. From spring to summer, the plant growth and aquatic ecosystems are particularly active. A standout experience is visiting the Wakka Primeval Flower Garden around September, when the red Suaeda media creates a spectacular sight. For the best experience, we recommend visiting during daylight hours when the 'Saroma Blue' of the lake surface is most vivid. For a beautiful sunset view, try visiting the area near Eura in Tsuru town toward the southeast in the late afternoon.

Experiences & Activities

Activities around Lake Saroma center on nature observation and culinary experiences. At the Wakka Primeval Flower Garden, you can feel the precious ecosystem of Hokkaido up close. For local flavors, visit facilities like 'Michi-no-Eki Saroma-ko' or 'Michi-no-Eki Air Land Wak chop,' where you can experience the local food culture. The area is famous for its abundant seafood, including scallops, oysters, salmon, and Hokkaido hairy crab. Enjoying these fresh delicacies is a primary joy of the region. Driving along the lakeshore is also a wonderful way to enjoy the changing scenery.

Surrounding Areas

There are several convenient facilities around the lake. Near the southern shore in Saroma Town, 'Michi-no-Eki Saroma-ko' offers accommodation and local specialty shops. On the Wak chop side, 'Michi-no-Eki Air Land Wak chop' features restaurants and an amusement park. The area is also well-equipped with hot spring facilities, such as 'Saroma Lake Onsen' and 'Kitami Kinoyu Onsen,' making them perfect spots to rest and relax after a day of sightseeing or driving.
