The spring's source: Yubatake

The Kusatsu Onsen boasts the highest output volume of natural spring water in Japan. To see what this means for yourself, head over to the hot water field of Yubatake, the symbol of Kusatsu located in the center of this hot spring town. Here hot spring water gushes forth into the open air, is cooled to bathing temperature and transported, undiluted, to nearby inns. An amazing 4000 liters of spring water emerge every minute, giving rise to the dense white smoke and sulfuric smell that floats around the town. Catch a whiff and you'll know you've truly arrived in Kusatsu. The traditional Yumomi method of cooling the spring water to bathing temperature without diluting its purity is also a sight to see. Hot spring workers stir the water with large paddles while singing local Kusatsu folk songs. Visitors can watch a performance and the more adventurous can even participate themselves.
