Geographical/topographical features
Nearly circular Lake Toya is Japan's third largest caldera lake. It is also Japan's sixth deepest lake, with a maximum depth of 180 m. The lake is famous for the clarity of its water: you can see driftwood and fish at the bottom of the lake on a canoe tour.
The four uninhabited islands of various sizes in the middle of the lake are collectively called Nakajima. Visitors can take a boat cruise (fare required) from the lakeside to the largest island.
Mt. Usu, which last erupted in 2000, and Mt. Showa-Shinzan―which suddenly rose on the plateau within just two years after a great eruption followed by the formation of a lava dome in 1944―soar near the Toyako (Lake Toya) Recreation Forest.
Historical/cultural features
The name "Toya" is said to be derived from "to-ya," which means "the shore of a lake" in the Ainu language.
The first onsen (hot spring) inn opened on the lakeside in the late 1910s, and Toyako Onsen began developing into a popular hot spring resort by the late 1920s.
In July 2008, Toyako Onsen found itself in the international spotlight as the venue for the 34th G8 Summit (the Hokkaido Toyako Summit). This brought Toyako Onsen to the attention of people both within and outside Japan.
Climate, flora and fauna
The area receives little snowfall and has a mild climate for Hokkaido.
Nakajima is home to wild Ezorisu (Hokkaido squirrel (Sciurus vulgaris orientals)) and Ezoshika (Yezo shika deer (Cervus nippon yesoensis)). Also, a variety of fish species can be found near the shore, including not only native species, but also many introduced species such as Himemasu (sockeye salmon (Oncorhynchus nerka)). Therefore, Nakajima attracts a large number of fishing enthusiasts in the summer (around June through August) when sockeye salmon, Sakuramasu (masu salmon (Oncorhynchus masou)), and Nijimasu (rainbow trout (Oncorhynchus mykiss)) can be caught (a recreational fishing fee is required).
Meanwhile, Yezo shika deer were introduced to Nakajima after World War II. Their swelling numbers have led the Ministry of the Environment and Hokkaido Prefecture to work on controlling the population.
The Toyako (Lake Toya) Recreation Forest boasts magnificent scenery that changes throughout the four seasons, with fresh verdure in the spring and crimson and golden foliage in the autumn. The entire area is within Shikotsu-Toya National Park.
The Recreation Forest is surrounded by a variety of points of interest, including volcanoes and hot springs. It also offers a number of facilities where visitors can experience nature, such as a lakeside campsite and the Lake Toya Forest Museum on Nakajima. Visitors can learn about the earth (i.e., our geological heritage) at the Toya-Usu UNESCO Global Geopark―designated as Japan's first UNESCO Global Geopark in 2009―by walking trails that provide a view of a crater, visiting the Volcano Science Museum, as well as going on guided canoe tours, riding horse, picking fruit and bathing in hot springs.
The Naka-Toya Campsite has "Kimundo-no-ie" Onsen (fee required), which uses only natural spring water and enables campers to casually enjoy the hot springs of Lake Toya.
