Deep in the hills of southern Hokkaido, about an hour’s drive from Sapporo, a valley exhales. Wisps of sulfurous steam rise from cracked earth the color of rust and ochre, hot springs gurgle in cauldrons of boiling water, and the faint smell of rotten eggs — the unmistakable scent of volcanic activity — hangs in the cool air. Welcome to Jigokudani, or Hell Valley: the dramatic geothermal heart of Noboribetsu Onsen, one of Japan’s most celebrated hot spring destinations.
Noboribetsu (登別) draws approximately 2.8 million visitors a year, making it Hokkaido’s most visited onsen town. The appeal is rooted in geology: the Noboribetsu volcanic system produces nine distinct types of mineral spring water, from sulfur and salt springs to iron and sodium bicarbonate pools. Each type has different therapeutic properties and a different appearance — from milky-white sulfur pools to clear salt springs — which is why Noboribetsu has been nicknamed Japan’s “hot spring department store.” For visitors who want to soak in world-class onsen surrounded by dramatic volcanic scenery, Noboribetsu delivers on every level.
This complete guide covers Hell Valley, the best ryokan (hot spring inns), Noboribetsu Bear Park, how to get here from Sapporo, and everything you need to plan a perfect one or two-night stay.

What Makes Noboribetsu Special
Nine Types of Mineral Springs in One Place
Most onsen towns in Japan specialize in one or two spring types. Noboribetsu is exceptional because its volcanic activity produces nine chemically distinct spring types within a compact area. The most famous is the white sulfur spring (ryuan-sen), which gives the water its characteristic milky appearance and sulfurous scent, and is said to be beneficial for skin conditions and joint pain. The salt spring (enka-sen) has a high mineral content similar to seawater and is warming; the iron spring (tetsu-sen) has a reddish tint from dissolved iron compounds.
Each of Noboribetsu’s large hotels draws from different spring sources, meaning that even a single overnight stay gives you access to a remarkable variety of baths. The best ryokan pipe multiple spring types directly to their bathhouses, allowing guests to rotate between radically different water chemistries over the course of a single evening — an experience that is essentially unique to Noboribetsu in Japan.

The Demons of Noboribetsu
You’ll notice them immediately: red-faced, fanged, club-wielding oni (demons) seem to be everywhere in Noboribetsu. They appear on manhole covers, shop signs, statues at the town entrance, and as costumed performers at the Jigoku Matsuri festival held each April. The demon theme is tied to the town’s “Hell Valley” identity — if the valley is hell, then it follows that its residents are demons. Far from being menacing, Noboribetsu’s oni have a cheerful, slightly absurdist quality. The most famous demon statue, a fanged red oni carrying a wooden club, greets visitors at the start of the Hell Valley boardwalk.
In April, the Jigoku Matsuri brings this mythology to life with a parade of costumed demons through the main street. The festival celebrates the spring emergence of demons from Hell Valley — an occasion that, in Noboribetsu’s telling, marks the renewal of the town’s spring waters and the beginning of the tourist season.
Top Attractions in Noboribetsu
Hell Valley (Jigokudani) — The Main Event
Jigokudani is a free-entry geothermal site covering approximately 450 square meters of volcanic landscape about a 10-minute walk uphill from the main hotel district. A well-maintained boardwalk loops through the valley, passing steaming vents, sulfurous craters, and boiling pools of blue-gray water. The largest feature is the Oyunuma (Big Boiling Lake), a 50-meter-wide pond with a surface temperature of 50°C, its edges permanently wreathed in sulfurous steam.
The boardwalk takes 30–45 minutes to walk in a loop, with several observation decks offering different perspectives on the valley. Beyond the main loop, a 30-minute trail continues uphill to the Okunoyu (Deep Spring), a smaller and less-visited area where the volcanic activity feels more raw and intimate. This extension is particularly rewarding in autumn (October–November) when the surrounding maple trees turn brilliant red against the pale steam.
Hell Valley is free to enter and open 24 hours. Night visits are atmospheric — the steam-lit darkness has an eerie quality — though the path can be slippery in winter and proper footwear is essential.
Noboribetsu Bear Park
A short drive or bus ride above the onsen town, the Noboribetsu Bear Park (Higuma Bokujyo) is home to approximately 80 Hokkaido brown bears (higuma), which are displayed in large open enclosures where visitors can observe natural bear behavior from viewing platforms and an underground glass-walled tunnel. The park also has a black bear section and a small museum about Ainu culture and the relationship between indigenous Hokkaido people and bears.
Access to the park is by gondola ropeway from a station at the edge of town, and the sweeping views from the mountain summit on clear days extend across the Pacific Ocean and the Uchiura Bay. Admission to the park (including the ropeway) is approximately ¥2,900 for adults. Plan about 2 hours for a comfortable visit. Bears are most active in the morning and late afternoon; midday tends to find them sleeping in the shade.

Noboribetsu Date Jidaimura (Edo Wonderland)
Next to the Bear Park entrance, Noboribetsu Date Jidaimura is a reconstructed Edo-period (1600–1868) village theme park where visitors can dress as samurai or geisha, watch ninja performances, participate in shuriken-throwing, and explore replica merchant houses and government buildings. It’s a deliberately theatrical experience — more entertainment than education — but done with enough production value to be genuinely enjoyable, especially for families and those new to Japanese history.
Admission is approximately £2,900 for adults, and various shows and workshops have individual fees. English-language commentary is available for some performances. Combined tickets with the Bear Park are sometimes available and worth looking for.
Oyunuma River Natural Footbath
A five-minute walk from the main Hell Valley viewing area, the Oyunuma River Natural Footbath is a shallow volcanic stream where you can remove your shoes and socks and soak your feet in naturally warm spring water flowing down from Oyunuma. The water temperature is typically around 40–42°C — perfect for a footbath — and the setting, surrounded by steam and volcanic rock, is unique. This is a genuinely memorable and completely free experience. Bring a small towel to dry your feet afterward, and note that the path to the footbath can be slippery.
How to Book & Get to Noboribetsu
Getting There from Sapporo
By train: Take the JR Limited Express Suzuran or Hokuto from Sapporo Station to Noboribetsu Station (approximately 1 hour 10 minutes, £3,760 one-way). From Noboribetsu Station, a local bus runs to the onsen area (approximately 15 minutes, £1,360). The full journey from Sapporo is approximately 1.5 hours including the bus connection.
By car: Approximately 1 hour from Sapporo via the Doo Expressway. There is free parking at most ryokan and near the Hell Valley entrance.
Book a Ryokan (Hot Spring Inn)
The classic way to experience Noboribetsu is to stay at least one night in a ryokan — a traditional Japanese inn — with a private or shared onsen. Noboribetsu’s large hotel-ryokan are famous for their multiple bathhouses; the Dai-ichi Takimotokan, for example, has 35 different baths fed by four spring types. Rates at mid-range ryokan typically run ¥15,000–25,000 per person per night with dinner and breakfast included.
For those on a tighter budget, several smaller ryokan and guesthouses offer rooms without meals starting from around ¥10,000 per person. Day-use bathing (higaeri onsen) is also available at most hotels for visitors who want to experience the baths without staying overnight; expect to pay £1,500–3,000 for day access including use of the changing rooms and lounges.

Tips & What to Expect
Best Time to Visit Noboribetsu
Noboribetsu is a year-round destination. Summer (June–August) is the peak tourist season with pleasant weather (20–26°C). Autumn (September–November) is the most scenic time, when the maple and birch forests surrounding Hell Valley turn vivid red and orange. Winter (December–March) offers the incomparable experience of soaking in outdoor hot springs with snow falling, and the sulfurous steam looks more dramatic against cold winter air. Spring (April–May) coincides with the Jigoku Matsuri demon parade and cherry blossoms on the lower slopes.
Onsen Etiquette for First-Timers
If you’re visiting a Japanese onsen for the first time, a few key points: onsen are used in the nude (swimwear is not permitted in most traditional facilities), and thorough pre-washing at the shower stations before entering the bath is mandatory. Most facilities have separate baths for men and women. Tattoos are not permitted at some traditional ryokan and public baths — check in advance if this applies to you, as some Noboribetsu facilities now accommodate tattooed guests in private baths.
For a comprehensive guide to onsen etiquette, ask at your ryokan front desk for the English leaflet most facilities provide to international guests. The staff at Noboribetsu’s larger hotels are experienced with international visitors and are accommodating about explaining customs.
Getting Around in Noboribetsu
The main hotel district, Hell Valley, and the footbath area are all walkable (the hotel district to Hell Valley entrance is approximately 1 km uphill). The Bear Park and Edo Wonderland are 10 minutes by bus or taxi from the hotel area. A free shuttle bus operates between most major hotels and the Bear Park gondola station during peak season. Local buses are infrequent; taxis are available at major hotels and cost approximately £1,000–1,500 for journeys within the onsen area.
Frequently Asked Questions
Is Hell Valley worth visiting?
Absolutely — and it’s free. Hell Valley is one of the most dramatic volcanic landscapes you can walk through in Japan, easily accessible on a boardwalk, and genuinely unlike anything else in Hokkaido. Even if you’re not staying overnight, the Hell Valley walk alone is worth a stop on the way to or from Sapporo.

Final Thoughts on Noboribetsu
Noboribetsu earns its reputation as one of Japan’s great onsen destinations through genuine substance: the volcanic scenery is dramatic, the spring variety is exceptional, and the ryokan experience — traditional inn, yukata robe, multi-course Hokkaido kaiseki dinner, and a night of soaking in multiple spring types — is one of the most restorative things you can do in Japan.
For first-time visitors to Hokkaido, Noboribetsu makes an ideal overnight stop between Sapporo and Hakodate (if traveling by the JR Hokkaido line), giving you a night of proper onsen immersion before continuing south. For those based in Sapporo, a day trip gives you Hell Valley and the Bear Park at minimum — though one night here will make you wish you’d stayed for two.
- Key takeaway 1: Hell Valley is free and extraordinary — don’t miss the Oyunuma River footbath nearby.
- Key takeaway 2: Stay at least one night to experience Noboribetsu’s nine spring types in their full variety.
- Key takeaway 3: Combine with the Bear Park for a complete Noboribetsu experience.

Nearby: Lake Toya and Lake Shikotsu
Noboribetsu sits between two of Hokkaido’s most beautiful volcanic lakes. Lake Toya (Toyako), approximately 40 minutes west by car, is a near-perfect circular caldera lake with a small island at its center and the snow-capped volcanic peaks of Usu-zan reflected in still waters. The lakeside town offers hot spring bathing with lake views, and Usu-zan is one of the few active volcanoes in Japan accessible by gondola. Eruptions in 2000 left a trail of preserved volcanic damage along the southern shore, a sobering reminder of Hokkaido volcanic geology. Lake Shikotsu, approximately 60 minutes north toward Sapporo, is Hokkaido’s deepest lake and one of Japan’s cleanest, with vivid turquoise water on sunny days. The area has excellent hiking on surrounding volcanic cones including Tarumae-san. In winter, the Shikotsu Ice Festival (January to February) illuminates ice sculptures with colored lights on the frozen lakeshore. Combining Noboribetsu, Lake Toya, and Shikotsu into a two to three day volcanic loop from Sapporo is one of the most rewarding itineraries in Hokkaido, passing through dramatically sculpted volcanic landscapes that are unique in Japan.
