Located in Kusatsu Onsen, this is a representative open-air bath that is one of the largest in Japan and has an overwhelming sense of openness.
Sainokawara Open-Air Bath is a day-trip hot spring facility in Kusatsu Onsen, a hot spring resort representative of Gunma Prefecture. It is located at the very back of Sainokawara Park, which can be reached on foot from the Yubatake in the center of the hot spring town. The main features of this open-air bath are its spaciousness and its design that is integrated with nature. The open-air bath, which is one of the largest in Japan at about 500 square meters, allows you to enjoy the high-temperature spring water flowing from the Yubatake. In addition, trees and flowers grow around the open-air bath, allowing you to spend a relaxing time while watching the nature of the four seasons.

Sainokawara Open-Air Bath uses the Bandai source and is a highly acidic (acid chloride sulfate spring, pH 1.6-1.7) spring water. The source temperature is high at about 97°C, and although it is adjusted to the appropriate temperature, it is important to note that the area near the source in the bathtub has a strong tingling sensation. The clear water contains about 500mg/kg metasilicic acid and about 15mg/kg free carbon dioxide, and its strong bactericidal power is effective against neuralgia, joint pain, and skin diseases. It is also rich in moisturizing ingredients, and is popular as a skin-beautifying bath that smoothes the skin.
