The Healing Waters: A Scientific and Spiritual Legacy
The secret to Noboribetsu’s diversity lies in its geological epicenter, Jigokudani (Hell Valley). This 450-meter diameter crater was formed by the eruption of Mount Hiyoriyama approximately 10,000 years ago. Today, it produces an astounding 10,000 tons of hot water daily. As groundwater filters through different subterranean mineral veins, it acquires varied chemical signatures before surfacing at temperatures sometimes exceeding 100°C.
- Sulfur Springs: Recognizable by their milky-white color and boiled-egg scent, these are prized for treating chronic bronchitis and arteriosclerosis.
- Salt Springs (Chloride): Known as “Atsu no Yu” (Heat Water), the salt prevents sweat evaporation, keeping the body warm for long periods.
- Iron Springs: These turn a distinct reddish-brown upon oxidation and are traditionally used to treat anemia and menopausal disorders.

Must-Visit Public Baths (Soto-yu)
The Yumoto Sagiriyu Onsen is the town’s primary public bathhouse. For a modest fee of roughly 500 yen, you can experience high-quality sulfur and alum springs. It maintains a nostalgic, “retro” atmosphere favored by locals. Note: Unlike luxury hotels, you should bring your own towel and soap or purchase them at the front desk.
Walking Guide & Scenic Spots
A half-day exploration on foot is the best way to see the volcanic wonders:
- Jigokudani Boardwalk: A well-maintained path that lets you walk directly through the steaming vents and bubbling geysers.
- Oyunuma Pond: A 30-minute hike leads to this massive sulfuric lake with a surface temperature of 50°C.
- Natural Footbath: Follow the Oyunuma River to a spot in the forest where you can soak your feet in the warm geothermal stream for free.
Local Gastronomy & Souvenirs
Don’t miss the spicy local specialties! Jigoku Ramen at “Aji no Daiou” offers customizable spice levels to test your bravery. For a unique meal, try Enma Yakisoba at “Onsen Ichiba,” made with flat Hokkaido wheat noodles and a secret spicy sauce. Popular souvenirs include “Oni” (demon) themed charms and local Hokkaido dairy products like milk pudding.
Cultural & Historical Context
The name “Noboribetsu” comes from the Ainu word Nupur-pet, meaning “a river with deep color”. In Ainu mythology, the hot springs were seen as a sacred gift from the mountains. The town is filled with statues of Yukijin (guardian demons) who are believed to protect the medicinal waters.
Practical Travel Tips
- Tattoos: Many large hotels like Dai-ichi Takimotokan allow guests with tattoos to use private baths.
- Cash: While hotels accept credit cards, small shops in the “Gokuraku Shopping Street” often require cash.
- Winter Gear: Hiking trails around Oyunuma can be extremely icy; wearing ice spikes on your boots is highly recommended.
2025-2026 Latest Updates

Safety & Manners
Always rinse your body at the shower station before entering the communal tubs. In Hell Valley, stay on the wooden boardwalks as the ground can be unstable and dangerously hot. Finally, please take all trash back to your hotel to protect the national park environment.
