A highland one-inn retreat to savor three private hot spring sources and a silky "cleansing bath"
Niigata Itoigawa City
"Sasakura Onsen Ryuunso" is a standalone inn perched on a plateau at an altitude of 460 m within Myoko-Togakushi Renzan National Park in Itoigawa City, Niigata Prefecture. It draws from three private hot spring sources, "Ryuun," "Yakushi," and "Senju." The water, with bicarbonate soda as its main component, is smooth and silky, almost like beauty serum. Highly regarded as a "cleansing bath," it helps remove dead skin cells and leaves the skin feeling beautifully smooth. The two large baths, each with a different atmosphere, offer a wide variety of tubs, including wild open-air baths, panoramic baths, bottle-shaped tubs, and reclining baths. Private baths with free-flowing spring water are also available, allowing guests to fully enjoy luxurious bathing while surrounded by the great natural beauty of the mountains.
