Guide
Kaiyodai is an observation point located on a 271m high hill in Nakashibetsu, Hokkaido. Because there are no tall buildings or obstacles nearby, the view is incredibly unobstructed, allowing visitors to see the distinct curvature of the horizon. This 360-degree panoramic view provides a rare sense of the Earth's roundness. The site has a long history, including the installation of the Nakashibetsu relay station in 1961, and it now serves as a premier scenic lookout.
The area has a history of being used as grazing land since 1929. The name "Kaiyo" was given in 1962 when a local school was established; the name reflects a wish for the area to develop brightly and prosper like the sun. Since the 1980s, the location has become a legendary destination for motorcycle travelers, gaining fame after being featured in Jyo Sasaki's novel "Looking Back at the Horizon."
The main attraction is the breathtaking 3-degree panorama. On clear days, you can spot the Notsuke Peninsula and even Kunashiri Island in the distance. The observatory building is a two-story structure, offering a high vantage point to observe the vast natural landscape. Additionally, the surrounding area features the geometric patterns of the windbreak forests of the Kesen Plateau, a characteristic landscape of Hokkaido.
Kaiyodai offers different expressions depending on the season, with particularly beautiful scenery from September to October. Visiting during bright daylight hours increases your chances of seeing the distant islands and the curve of the horizon clearly. However, since visibility can be limited by wind or weather, visiting on a clear, sunny day is highly recommended.
On the first floor of the observatory, you can visit "Risu no Mori," a gelato shop where you can enjoy local flavors. It is a popular spot for travelers to take a break during a drive or motorcycle tour. Whether you are enjoying a refreshing treat, taking photos against the vast horizon, or simply soaking in the silence of nature, the experience is truly special.
The site is easily accessible, just a 15-minute drive from Nakashibetsu Airport. The surrounding roads are perfect for scenic drives through the Kesen Plateau, allowing you to immerse yourself in the vastness of Hokkaido's nature. Nearby natural landmarks like the Notsuke Peninsula are also worth exploring.
As the observatory is located on a hill, it can be quite windy and cooler than the surrounding areas. We recommend bringing windproof and warm clothing, especially in autumn. While the observatory itself is open and free to enter, please respect the local environment and follow public etiquette while taking photos.
