Kaiyo-dai Observatory
An observation deck with a 330-degree view where you can see the curvature of the Earth
An observation deck where you can enjoy a 330-degree panoramic view, overlooking the grid-pattern windbreak forests, a Hokkaido Heritage site, and the distant horizon.
Standing at the observation deck, an overwhelming 330-degree view spreads before you. Grid-pattern windbreak forests designated as Hokkaido Heritage are etched into the land like a checkerboard, and beyond them, the horizon continues in a gentle arc. On clear days, you can clearly see the curve of the horizon where sky and earth meet, offering a moving experience of visually confirming that the Earth is round. At the observation deck where wind blows through, gazing over the vast land makes you forget the hustle and bustle of daily life, and your heart is cleansed by the grand scale of nature. The colors of farmland changing to green or golden with the seasons, roads extending into the distance, and scattered ranch landscapes tell of Hokkaido's characteristic magnificence.
The cafe inside the observation hall offers menus using rich milk from Nakashibetsu, the dairy kingdom. The signature menu item "Shiawase no Hachimitsu Soft" is a limited edition using plenty of honey harvested at Kaiyo-dai. The gentle sweetness of honey melts into the soft ice cream, spreading a delightfully smooth taste in your mouth. The moment of savoring this while viewing the spectacular scenery is a special time that can only be experienced at Kaiyo-dai.
