Enjoy a silky beautifying hot spring and a 100°C sauna right in front of Joetsu-Myoko Station
Niigata Joetsu City
"Natural Hot Spring Kamabuta no Yu" is a station-front natural hot spring with outstanding access, located right in front of Joetsu-Myoko Station on the Hokuriku Shinkansen. The hot spring water, gushing up from 1,500 meters underground, is famous for its rich, silky texture, almost like a thick sauce, and is highly popular as a beautifying bath that leaves the skin smooth and supple. The sauna facilities include two types: a powerful high-temperature sauna set at 100°C, and a low-temperature salt sauna with beautifying benefits. After tightening up in the bubble-equipped cold plunge bath, you can enjoy a refreshing outdoor air bath in an open space scented with cedar. A blissful moment for travelers in between trips or on the way home from work.
