Tenninkyō Onsen is a small geothermal hot spring village in the Daisetsuzan National Park, Hokkaido, nestled in a dramatic gorge of the Chubetsu River surrounded by vertical basalt columns and waterfalls, whose simple and sulfurous mineral waters provide bathing facilities in one of the most spectacularly wild natural settings in Japan. The name Tenninkyō means Ravine of Heavenly Nymphs, evoking the ethereal beauty of the gorge with its towering rock walls, cascading falls, and the sense of being enclosed within a primeval volcanic landscape far from human civilization. Tenninkyō Onsen is a gateway to the interior of the Daisetsuzan wilderness, used as a trailhead for hikers heading into the alpine core of Hokkaido's largest national park, and its thermal waters serve both the adventurous trekkers who pass through and the visitors who come simply to experience the transcendent landscape of this uniquely beautiful volcanic gorge.

Insider tip — Tenninkyō Onsen sits in a deep limestone gorge carved by the Chubetsu River in Daisetsuzan National Park, where dramatic columnar basalt cliffs tower above the wooden bathhouses. The sulfurous spring water at 44°C pours from volcanic sources hidden beneath the gorge walls, giving the water a distinctive milky blue-green tint when it pools. The gorge is famous for its twin waterfalls, Hagoromo and Ginga, visible on a short trail from the spa buildings. Autumn transforms the gorge walls into a tapestry of gold and crimson, drawing photographers from across Hokkaido.
