Jigokudani means Hell Valley. The crater is about 450 m across and covers 11 hectares, and its springs send about 10,000 tonnes of hot water a day down to the onsen town's hotels.

Jigokudani is an explosion crater about 450 m across, full of steaming vents and boiling springs, that feeds the onsen town with about 10,000 tonnes of hot water a day. It is free. A ramp, no steeper than 8%, runs from the park service centre to the observatory. Oyunuma pond and a natural footbath on the Oyunuma river are nearby, also free.
- Number 3 of ten on our list for Muroran.
- Free to visit — train ¥470 each way from Higashi-Muroran (+¥850 reserved seat); bus ¥450 each way.
- On a 4–6h ashore call our verdict is "Only by taxi" — about 35 minutes each way by taxi, about ¥13,600 each way (our estimate).
- Open-air — no opening hours published.
- This needs 7 hr, so it only fits a 9-hour call or longer. On a shorter one it will cost you the ship, not the view.
- It is a view, so it is weather. Check the morning sky before you commit the hours.
Things worth knowing
- Buy your return train ticket at Higashi-Muroran on the way out: the machines have had queues on big-ship days.
- Donan buses take cash, their own card or PayPay, not IC cards, and cannot change ¥2,000, ¥5,000 or ¥10,000 notes.
Noboribetsu Hell Valley and your ship
Both pins on one map, so the distance is a fact rather than a feeling.
Where the 7 hr goes
The hour before all-aboard is not in this bar; it is already set aside. The minutes are our estimates from timetables and maps, not timed on the ground.
If your ship is late, cut the 4 hr in the middle. Never cut the hour at the end.
