Lake Hyoko


Wild swans right in front of your eyes!

  Lake Hyoko was created as an agricultural reservoir in 1639. It was designated a national monument as the landing place for swans in 1954 and was designated a wetland by the Ramsar Convention in 2008.
  The first swans arrive in early October every year and stay until late March. Between 5,000 and 6,000 swans migrate here during the peak season in late November. You can buy food at the lake to feed them.
  Early morning and evening are the best time to see the swans. There is an air-conditioned observatory room at the lake.
  In the spring, cherry blossoms decorate the lake. Some swans remain at the lake into the spring every year, and you can see swans swimming alongside ducks. In the summer, the lake is filled with a variety of flowers and plants, so you can enjoy it year round.
