Known as the lake of swans, Hyoko Lake has been designated a national natural treasure.

Flocks of swans reside here from early October to late March. Between 5,000 and 6,000 swans are here at their peak in late November. Tundra swans, Whooper swans and Mute swans can be seen and visitors can buy designated food for feeding each variety.

Early mornings and evenings are the best time to see the swans. There is also a viewing shed by the lake to keep visitors warm even on colder days.

The lake is surrounded with light pink cherry blossoms in spring while the surrounding grounds are covered with bright yellow Forsythias in bloom. Some swans live here year-round and visitors can see these along with ducks swimming elegantly together with cherry blossoms in the background.
