Steam and Silk: Day-Tripping to Hoheikyo Onsen’s Forest Baths
Forest-steeped baths, dam views, and a curry counter — the perfect Hokkaido day loop
The first thing that arrests you at Hoheikyo Onsen is the way the forest exhales. Steam sheets off the black, stone-edged baths like the breath of the valley itself, and when you step toward the open-air rotenburo the world narrows to wind, water, and a racket of leaves clacking in the pines. Behind the pools, the Hoheikyo Dam’s turquoise reservoir sits like a jewel cut out of the mountains — sudden, clear, and impossibly calm. In the high seasons the slope above the dam is a living postcard: cherry greens in spring, thick emerald in summer, incandescent crimson and gold in autumn, and in winter a hush of white that makes the onsen’s steam look almost obscene in its warmth.
Trail Wisdom
Book a guided bike or hike
Small-group mountain bike and green-season hiking tours include transport from Sapporo and a local guide — they simplify logistics and enhance safety.
Bring a dry towel and cash
Some onsen shops prefer cash and although towels may be available on tours, your own quick-dry towel is handy for comfort and hygiene.
Respect onsen etiquette
Shower and rinse thoroughly before entering baths, keep the small towel out of the water, and keep noise to a minimum to honor local customs.
Time your visit for light and crowds
Mid-morning in autumn gives the best light on the dam; early afternoon is livelier with local diners if you want a sociable meal after soaking.

Conservation Note
Stay on marked trails, pack out waste, and use organized tours or public transport to reduce road traffic and protect the valley’s fragile ecosystems.
Jozankei valley, where Hoheikyo sits, evolved into a mountain retreat for Sapporo during the 20th century and retains a long tradition of hot-spring bathing.
