Amakazari Onsen

Amakazari Onsen—Rain Decoration Spring—lies within the Myoko-Togakushi Renzan National Park in Itōgawa City, Niigata Prefecture, where the distinctive volcanic peak of Amakazari-yama (Rain Decoration Mountain) rises within a national park landscape of exceptional volcanic and ecological diversity, its name evoking the misty cloud formations and decoration-like patterns of rain and cloud that surround the mountain peak in the moisture-laden atmosphere of Japan's heaviest snow country. The simple alkaline waters provide the gentle, restorative mineral soak that serves hikers and climbers visiting this mountain spring—a facility operated on natural generator power, lit at night only by kerosene lamps, offering the authentic experience of a genuine mountain wilderness thermal retreat with no electric lighting in guest rooms or bathing areas. This lamp-lit mountain spring within a national park of volcanic beauty represents one of Niigata's most atmospherically authentic and environmentally immersive thermal spring experiences.
