At Yubatake in Kusatsu-cho, you can enjoy the magnificent sight of 4,000 liters of hot springs gushing out every minute. The steam rising from the source, which is regulated by passing it through wooden barrels and exposing it to air, is fantastical. With a high acidity level of pH2.1, it has excellent sterilizing effects and is expected to be effective against joint pain and hypertension. Don't miss the traditional "time bath" experience either!
