In winter, this lagoon is home to over 75,000 varieties of birds, including geese and tundra swans. The ornithological reserve also provides shelter to endangered aquatic plants along with very rare giant water-insects. From behind the huge glass windows, you can observe the wildlife outdoors with the help of telescopes and binoculars (and helpful volunteers). The magnificent view is depicted by Tsubasa in the foreground and Mount Daisen in the rear.
