917. Nonokaze Resort, Toyako Onsen, Hokkaido (pt.4) ★★★ About the onsen: 4. An indoor area designed like a Showa-era sento. This is a new build, but it does a very good job of recreating the feel from the entrance all the way to the baths themselves. It is comfortable to breathe inside. 4.1. Large bath with cloudy yellow water. Temperature 41. 4.2. Small bath with clear water. Temperature 43. 08.04.2026 09.04.2026
