Tobira Onsen Myojinkan

Three natural hot spring baths face the forested mountainsides of Yatsugatake National Park, open around the clock and framed by nothing but trees. This classic ryokan, half an hour outside Matsumoto, keeps its rooms spare by design: tatami, shoji screens, and floor-to-ceiling views do all the work. Some rooms add a private open-air onsen bath. A shuttle runs to and from the station, which is two and a half hours from Tokyo and feels like considerably more.
