MountainsAbout
The bath here draws on Ichiyama-no-yu (市山の湯), a spring under the Tsuchiide hot spring area at the base of the Oze Iwakura ski slopes. The water is smooth on the skin with a faint scent of sulfur, and the indoor bath comes with a sauna, a cold plunge and washing stations, split into separate baths for men and women. Most guests are here for skiing at Oze Iwakura or a day out around Oze, and the hotel runs a separate day-use side too: its onsen and lounge brand MONE (木音の湯) pairs the bath with a reading lounge, a bar lounge with free-flow drinks, a kids' play area and a coworking corner facing the ski slopes. Rooms come in Japanese, Western and mixed styles.
