MountainsAbout
MUWA NISEKO is a hotel in Hirafu with a natural hot spring bath on its top floor, an infinity-edge rotenburo said to be the first of its kind in Japan, looking straight out at Mt. Yotei. There's also an indoor bath, a sauna, and a private (kashikiri) bathing option for guests who'd rather bathe alone, and some suites come with their own in-room onsen bath.
