Log in to manage your own bucket list! Why travel to Unzen Onsen?
At Unzen Jigoku, acidic gases hiss and bubble out of the ground just outside the village. Paths go between steaming vents and sulfur-stained rock. The site has a darker side as well, since Christians were martyred here in the 17th century. The springs are strongly sulfuric and acidic and feed the village's public baths such as Shin-yu and Yunosato as well as the ryokan baths. Day visitors can use most of them, so a soak fits even a short stop. Nita Pass, a short drive from the village, has a ropeway that goes up toward the peaks and is especially popular in autumn. From the upper station a ridge route leads to the summit of Fugendake (4,500 ft) in about an hour. The mountain is part of Unzen-Amakusa National Park and hiking here is good in every season. A night or two covers the village, the hells and a hike. Unzen also pairs well with Shimabara, which has a castle and a samurai district about 50 minutes away by bus. Nagasaki fits on the way in or out.

How to travel to Unzen Onsen

Where to stay in Unzen Onsen
Unzen Onsen is known for traditional ryokan and onsen hotels that draw straight from the sulfur springs. Staying in the village is the practical choice because buses are limited. A dozen or so larger resorts form the core, usually with private and shared baths, a yukata (cotton robe) to wear around the streets and dinner and breakfast included. Smaller guesthouses and inns fill out the choices. Rooms book up around autumn foliage and national holidays, so reserve early for those dates. Booking dinner with your stay is worth it since few places stay open late. If you'd rather be in a town with more dining and shopping, Shimabara is a bus ride down the mountain.
Hotel recommendations

How to get around Unzen Onsen
The village is compact and most of what you'd come for, including the hells, the public baths and the ryokan, is within walking distance. Streets go up and down with the slope, so allow extra time with luggage. Beyond the village, getting around is harder because public transport is thin.
Nita Pass:
No buses run between the village and Nita Pass, where the ropeway starts. A taxi is a short ride and walking takes about an hour, so a rental car or a taxi booked through your inn is the practical choice.
Buses and car:
Buses connect the village with Shimabara roughly every hour for sights on the peninsula. Mountain roads can ice over in winter, so check conditions and tires before driving.
Food in Unzen Onsen
Meals in Unzen Onsen center on the ryokan, where a multi-course or buffet-style dinner and breakfast usually come with the room rate. The village has a handful of restaurants and cafes. Few places stay open late, so plan dinner at your inn or eat early if you're staying elsewhere. Kaiseki dinners are heavy on fish and meat, so vegetarians and others with dietary needs should tell the inn in advance.
Jigoku mushi:
The local specialty is jigoku mushi, food steamed in volcanic vents. Shops by the hells sell eggs steamed in the vents.
Yu-senpei:
Yu-senpei are thin, lightly sweet wafers baked with hot spring water. They're sold as souvenirs or quick snacks and one shop in town bakes them by hand where you can watch.
Nagasaki dishes:
Nagasaki Prefecture cooking also shows up, including champon (a noodle soup of pork and seafood) and Shimabara guzoni, a rice cake soup with many ingredients.

Safety information overview
General safety
Crime is very low but the hazards here are natural. Volcanic gas around the hells and on Mount Unzen can be harmful, so stay on marked paths and obey closures. Fog and ice make mountain roads and trails risky in winter.
Health & Medical
The village has limited medical facilities. Larger hospitals are in Shimabara, Isahaya and Nagasaki, about one to two hours away. English is limited. People with asthma or heart and blood pressure problems should take care with volcanic gas and hot baths.
Accessibility
The village sits on a slope with hills and steps while the Jigoku paths include stairs and uneven sections. Some inns have steps at the entrance, so ask about accessible rooms. Nita Pass has no public transport, so a car or taxi is needed.
Tap water
Tap water is safe to drink in Unzen Onsen and in the rest of Japan. Hot spring water is sulfuric and not for drinking. Shops and vending machines sell bottled water and tea, which helps on hikes.
