The largest and most popular onsen facility is, of course, at Madarao Kogen hotel, with guests at the hotel using the onsen for free and outside guests need to pay the onsen entrance fees to use the facilities. The onsen is high quality and is well kept, open from early morning to late in the evening, almost midnight most nights, and provides a soothing and beautiful environment for guests to relax in.

Another smaller and slightly more out of the way onsen is available at the Nakano Hotel. This onsen is an outdoor one, with a smaller bath but arguably a better environment. It’s closed every Tuesday, though, and costs roughly 450 yen for adults, and 300 yen for high school students. This onsen is open from around 10 a.m. until 9 p.m., with shorter opening hours than the larger onsen at Madarao. The natural surroundings of the outdoor onsen make for a stunning scenic relaxation session, and definitely provide tranquility that the larger and busier onsens lack.
