Noboribetsu Jigokudani (Hell Valley)
Hokkaido Region
Noboribetsu Jigokudani, also known as Hell Valley, is a volcanic crater valley formed by the eruption of Mount Hiyori. Spanning approximately 450 meters in diameter and covering an area of about 11 hectares, it features numerous fumaroles and boiling hot springs along the valley. This geothermal activity produces a surreal landscape of bubbling vents and steam that has earned it the name "Hell Valley," believed to be the home of demons in local folklore. The valley is a major source of hot spring water, supplying around 10,000 tons daily to the hotels and ryokan in the nearby Noboribetsu Onsen hot spring town, the largest hot spring resort in Hokkaido. Visitors can explore the area via paths and observation points, including wheelchair-accessible slopes leading to the Hell Valley viewpoint. The dramatic natural scenery and the unique volcanic activity make it a must-see destination within Shikotsu-Toya National Park, offering a glimpse into the powerful geothermal forces shaping the region.
