Hoheikyo Onsen: A Primeval Thermal Oasis and the Legendary “Curry Sanctuary” of Sapporo
Hoheikyo Onsen is a destination that defies the standard expectations of a suburban resort. Located just beyond the famous Jozankei district, deep in the rugged valleys of the Toyohira River, it is an enclave of raw nature and uncompromising quality. Known throughout Japan for its unique blend of world-class thermal purity and its strangely famous authentic Indian curry, Hoheikyo offers an experience that is both spiritually grounding and culinarily surprising. This is a place where “Gensen Kakenagashi” is taken to its absolute extreme—where the water is never stored in tanks or exposed to the air until it touches your skin. Surrounded by a magnificent traditional garden hand-crafted by master landscapers, Hoheikyo Onsen provides a profound sensory retreat where the steam of the volcanic earth meets the spices of the Himalayas.

The Healing Waters: The Science of “Tank-Free” Purity
The defining scientific feature of Hoheikyo is its commitment to “raw” water. While most hot springs use storage tanks to manage temperature, Hoheikyo pipes its 70°C water directly from the subterranean bedrock into the tubs. This prevents oxidation, ensuring that the water’s “reduction potential” remains at its highest. Scientifically, this means the minerals are chemically active, providing a superior antioxidant effect on the skin. The springs are exceptionally rich in sodium chloride and bicarbonate, creating a “silky coating” effect. Upon exiting the bath, the minerals form a fine film on the skin that blocks the evaporation of sweat, keeping the body’s core temperature elevated and its surface remarkably smooth. The outdoor baths are among the largest in Japan, accommodating up to 200 people simultaneously, and are arranged with massive natural boulders that allow you to soak as if you are part of the ancient canyon floor.

Must-Visit Public Baths (Soto-yu)
Hoheikyo itself is a premier “Soto-yu” experience. Unlike communal city baths, it offers a “thematic” escape. The Kamui-no-yu outdoor bath is designed with rocks from the riverbed and provides a direct view of the mountain cliffs. For those seeking variety, the Jozankei Gensen Park nearby offers free footbaths and a “forest bath” atmosphere. A key highlight of Hoheikyo is the Outdoor Cold Plunge, which allows for the “Hot-Cold” therapy cycle, highly recommended for boosting the immune system during the Hokkaido winter.
Walking Guide & Scenic Spots
The “Hoheikyo Nature Loop” starts at the Hoheikyo Dam. From the onsen terminal, take the eco-friendly hybrid bus (or a 20-minute walk) to the dam site. This is ranked as one of Japan’s top 100 dam lakes and is world-famous for its autumn foliage. Cross the dam wall for a view of Lake Jozan and the vertical cliffs of the gorge. For photography, visit the Observation Deck overlooking the dam’s spillway. In winter, the Kamakura (Snow Hut) Village at the onsen is a must-see, where you can enjoy hot drinks inside giant hand-built snow domes.
Local Gastronomy & Souvenirs
The culinary identity of Hoheikyo is inextricably linked to Indian Curry. The restaurant within the onsen facility is staffed by Indian chefs and is legendary for its huge, fluffy naan and spicy butter chicken. It is not uncommon for visitors to drive from Sapporo solely for the curry! For a local Hokkaido flavor, try the 100% Buckwheat Soba made with mountain water. For souvenirs, look for Hoheikyo Curry Retort Packs, local Kappazake (sake served in traditional cups), and handmade Onsen Manju from the shops in central Jozankei.
Cultural & Historical Context
Hoheikyo was developed by a visionary who believed that the power of hot springs should be preserved in its most “primordial” form. The garden surrounding the baths took over 30 years to perfect, with every stone positioned to reflect the natural hydrology of the river. The name “Toyohira” comes from the Ainu word tuye-pira, meaning “shattered cliff,” referring to the dramatic geology of the gorge. This site remains a vital power spot, believed by locals to clear the mind of modern distractions through the sheer scale of its rock and water.
Practical Travel Tips
Currency: Hoheikyo is strictly Cash Only for both bathing fees and the curry restaurant; ensure you have enough Yen before leaving Sapporo. Transportation: The bus from Makomanai Station is free for those who book a day-trip lunch package (confirm current details). Crowds: Weekend lunch hours for the curry restaurant can see wait times of up to 60 minutes; arrive by 10:30 AM to beat the rush. Tattoos: Hoheikyo is relatively Tattoo-Friendly, though large pieces should be covered or discussed with staff at the entrance.
2025-2026 Latest Updates
The Yukituro 2026 FINAL event at the nearby Jozankei Shrine (Jan 27 – Feb 3) will be the last time to see the snow lantern festival in its traditional format, making this winter a once-in-a-lifetime visit. Additionally, the Hoheikyo Autumn Night Illumination has been expanded for the 2025 season, offering light-up events at the dam observatory from late September to mid-October.
Safety & Manners
The water at Hoheikyo is mineral-heavy and can make the rocks in the outdoor bath very slippery—walk carefully. Always rinse your body before entering the tub to protect the raw spring quality. In the restaurant, remember that it is a quiet rest area as well; keep your voice down to respect those napping after their bath. Finally, take your trash with you to preserve the pristine beauty of the Shikotsu-Toya National Park.
