Sapporo in Autumn: Hoheikyo Dam and Hoheikyo Onsen Tour

Looking for Japan's 'koyo' fall colors? This seasonal tour will take you from Sapporo to the stunning Hoheikyo Dam and then to the serene Hoheikyo Onsen to unwind and enjoy the vibrant autumn colors!
After departing Sapporo Station, our tour begins at the Hoheikyo Dam. The dam itself is arch shaped, 102.5 meters in height and 305 meters in length. It was completed in 1972 for flood control and to provide hydroelectric power to the growing City of Sapporo (now Japan’s 5th largest city).

The Hoheikyo Dam is nestled deep in the Toyohira River valley, at the entrance to Shikotsu-Toya National Park, southwest of Sapporo, near the Jozankei Onsen area. The reservoir lake, created by the dam, is a calm, turquoise mirror reflecting the mountains—a striking contrast to the towering dam wall. In autumn (October), this becomes one of the best koyo (fall foliage) spots near Sapporo, with vibrant reds, oranges, and yellows blanketing the mountainsides. In spring and summer, lush greenery and wildflowers flourish, while in winter, the entire valley is wrapped in a snowy silence (though access is limited during heavy snow).

Hoheikyo Dam offers panoramic views all around. The walking trails (The Dam Loop Trail, Dam Crest Walk) are easy, paved paths leading to the dam, lake, and surrounding forest trails, suitable for all ages. Although Hoheikyo Dam is enjoyable all season, a visit mid-September to late October is highly recommended.

Our next stop will be down the road at The Hoheikyo Onsen. Hoheikyo Onsen is more than just a bath—it’s a deeply relaxing experience surrounded by Hokkaido’s untouched nature. Whether after a walk around the dam or as a day trip from Sapporo, it’s the perfect way to unwind in Japan’s natural healing waters. The water here is gentle on the skin and suitable for all ages. Solo travelers as well as people with families will be openly welcomed here. The waters at this onsen are especially beneficial in the improvement of blood circulation and to relieve muscle and joint pain as well as other health benefits.

This is a must-see tour for any Hokkaido itinerary. Especially in autumn! Visitors to this onsen will witness one of the largest outdoor baths in Hokkaido. Stunning views all year round with autumn foliage being the most attractive season to visit and soak here. Gender-separated indoor/outdoor baths with modern comforts.
