Located in the center of the town is Yubatake, a huge upwelling of hot spring water that is a symbol of Kusatsu Onsen. This "field of hot water" is one of the largest natural springs producing 5,000 liters of hot water every minute. Here, you can experience the intense odor of sulfur and watch billowing clouds of steam. The hot water, which is an extremely hot 55 degrees Celsius when it comes out of the ground, passes through a series of wooden channels and is then sent to individual Ryokan inns in the town, cooling it along the way. The sulfur phenocryst which accumulates is popular as a souvenir and is called "Yu-no-Hana", or in English "Hot Water Flowers".
