Hoshi Onsen Chōjukan

"This stand-alone lodge with little-known hot springs is found inside the Joshin'etsukogen National Park. Its key feature is a large Rokumeikan-style bath called Hoshi-no-Yu. Hoshi Onsen Chojukan is one of only twenty locations in Japan that features a hot spring that bubbles up from beneath the bather. The lodge has been designated a National Tangible Cultural Property. Rooms have a tatami (woven-straw) floor and a low table with seating cushions. A seating area at floor-to-ceiling windows offers nature views, and guests sleep in traditional futon bedding. Yukata robes are provided, while toilets and bathing facilities are shared. "
