Japan Jigoku Cooking Guide 2025: Steam-Cooking at Beppu's Hell Springs
In Beppu — Japan's geothermal capital on the island of Kyushu — steam rising from the earth is not just a spectacle: it's a cooking method. Jigoku mushi (hell steaming) is the tradition of cooking food directly in the natural 98°C steam vents that define this extraordinary city. Eggs, sweet potato, clams, and chicken cooked this way develop flavours unlike anything from a kitchen stove.

What is Jigoku Mushi?
Jigoku mushi (地獄蒸し) literally means "hell steaming" — cooking food using the natural high-temperature steam that rises from Beppu's geothermal vents. Beppu, a city on the northeastern coast of Kyushu, sits atop one of the world's most active geothermal zones, producing approximately 100,000 kilolitres of hot water daily from thousands of natural springs. The Beppu hells (jigoku) reach temperatures of 95–100°C — hot enough to cook food efficiently without any external heat source.
The History of Jigoku Mushi
Beppu residents have cooked with geothermal steam for centuries — historical records indicate the practice dates to the Edo period (1603–1868). Local fishermen and farmers used natural steam vents to prepare food without wood fuel in an era when cooking fuel was scarce. Today, the tradition continues as a unique culinary and cultural attraction, with dedicated public jigoku mushi facilities open to visitors who want to cook their own ingredients in the authentic Beppu way.

- • Beppu produces 15% of Japan's geothermal output
- • Second highest geothermal output globally after Yellowstone
Beppu Hells Overview
Beppu's eight "hells" (jigoku) are naturally occurring hot spring pools of extreme temperature and varied mineral composition. Each hell has a distinct character — different colours, temperatures, and visual effects created by their unique geochemistry.
Umi Jigoku (Sea Hell)
Most FamousCobalt-blue spring created by dissolved minerals — a vivid turquoise pool at 98°C that resembles a tropical sea. Large lotus leaves float on cooler connected ponds. Has the best-developed visitor facilities including a jigoku mushi cooking area. Admission: ¥400.
Oniishibozu Jigoku (Demon's Head Hell)
Mud PotsGrey mud bubbles that resemble the shaved heads of Buddhist monks. Thick geothermal mud heated to 99°C creates mesmerising slow-motion bubbling. Adjacent footbath and sand bath facilities for visitors. Admission: ¥400.
Chinoike Jigoku (Blood Pond Hell)
Most DramaticJapan's oldest natural hell — a rust-red spring whose colour comes from iron compounds and clay. The deep crimson water at 78°C is visually extraordinary, especially with steam rising. Gift shop sells skincare products made from the mineral-rich spring water. Admission: ¥400.
Yama Jigoku (Mountain Hell)
Zoo & CookingUses geothermal heat to warm an animal habitat — hippopotamuses and flamingos are kept in enclosures heated by natural steam. Jigoku mushi cooking facilities available here. Unusual combination of cooking experience and tropical animal zoo. Admission: ¥200.
Combination Ticket
A combination ticket covering all 8 hells costs ¥2,200 per adult (significant saving vs individual entry). The Kannawa cluster (6 hells) and Shibaseki cluster (2 hells) are 10 minutes apart by bus — allow a full day to see all eight. Buy the combo pass at the first hell you visit.
Where to Cook at the Hells
Not all eight hells offer cooking facilities. The main jigoku mushi cooking experiences are concentrated at specific locations with purpose-built steam cooking infrastructure.
Jigoku Mushi Kobo Kannawa (Recommended)
A dedicated public jigoku mushi facility in the Kannawa hot spring district — the most visitor-friendly option in Beppu. Visitors purchase ingredients from a nearby market stall (eggs, vegetables, sweet potato, corn, pork) and use the purpose-built steam boxes (mushi-kama) to cook them under a staff member's guidance.
- • Cooking fee: ¥510 (covers use of steam box, up to 30 minutes)
- • Ingredients: purchased separately (¥200–¥1,000 depending on selection)
- • Hours: 10:00–20:00 (last cooking 19:30)
- • English menu and instructions available
- • Location: 5-minute walk from Kannawa bus stop
Hotel & Ryokan Jigoku Mushi
Many Beppu ryokan and hotels with their own hot spring sources offer in-house jigoku mushi cooking as part of their dining experience. Some include it in the room rate; others charge ¥1,500–¥3,000 as a cooking activity. This is often the most relaxed way to experience jigoku mushi — ingredients are fresh, setup is handled for you, and you eat in the ryokan dining room. Ask when booking if the property offers this.
What to Cook: The Jigoku Mushi Menu
The natural high-temperature steam of Beppu's geothermal vents creates distinctive cooking results — particularly for eggs, shellfish, and root vegetables, which develop intensely concentrated flavours with pure steam cooking.
Must-Try Items
- • Jigoku Tamago (Hell Eggs): Eggs steamed 15 minutes — the whites become silky and the yolks develop a unique mineral richness. Available at all cooking facilities.
- • Satsumaimo (Sweet Potato): Steam 30 minutes — the natural sugars caramelise without added sweetener. A local staple.
- • Corn on the cob: 20 minutes — remarkable sweetness retained. Season with the provided salt flakes.
Intermediate Options
- • Shumai dumplings: 8–10 minutes — excellent textural contrast
- • Chicken thigh (seasoned): 20–25 minutes — juicy with no added fat
- • Clams (asari): 5–7 minutes — the mineral-rich steam enhances the ocean flavour
- • Tofu: 10 minutes — silken warmth that absorbs the mineral character of the steam

Beyond the Hells: More Beppu Experiences
Beppu Sand Bath (Sunayu)
Unique to Beppu — bathers are buried in geothermally heated sand (40–50°C) on the beach at Shoningahama. The sand's pressure and heat create a full-body therapeutic effect unlike a regular onsen. Staff shovel you in; you remain buried for 10–15 minutes. Rental yukata included. Open 08:30–18:00 (seasonal). Fee: ¥1,500.
Kannawa Onsen Town
The Kannawa district is Beppu's most atmospheric hot spring neighbourhood — steam rises from road gutters and rooftops throughout the neighbourhood. Walking the streets on a cool evening, surrounded by billowing white steam and the smell of sulfur, is an experience that stays with you. Multiple public baths (communal onsen at ¥100–¥200) allow locals and visitors to bathe together. Traditional ryokan in Kannawa offer the full geothermal lifestyle experience.
Getting to Beppu
Beppu is easily reached from Fukuoka (Hakata station) by limited express train in approximately 2 hours (Sonic or Nichirin express, ¥4,000–¥5,500).
