Moegi no Yu
Time Out says
10 minutes' walk from Okutama Station on the JR Ome line, this onsen offers some welcome respite after a day spent hiking in the local mountains. The facilities include indoor and outdoor rotenburo baths, as well as a communal foot bath. A two-hour soak costs a not-unreasonable ¥780 for adults (which goes up by ¥200 per hour if you stay longer), though be warned that this doesn't include a towel.
