Nanadaru Onsen Hotel

200. Nanadaru Onsen Hotel, Kawazu Visited for day-use bathing for 1000 (listed hours 9:00 to 19:30). Didn't find the owner right away — about five minutes later he pulled up in a car and let me in for day-use, so there might be risks with a random visit. Small towel costs 100, but they gave one for free. They stamp the Shizuoka 60 Onsen book. I got to use the outdoor bath, but later realized there's also a mixed cave bath (either it's not available for day-use, or there was a language barrier and I just didn't understand). Large cozy outdoor stone bath with a pleasant nature view. Clear water, temperature between warm and hot. A gentle breeze was blowing and you could zone out for a long time. Nice place, can recommend for a day-use visit in Kawazu even with just the outdoor bath, and if you can get into the cave bath too — definitely go.
