The hot water here, aside from being very hot, is high in sulfur, meaning it has a very egg-y smell. Kusatsu Onsen has become a favorite holiday or weekend retreat for visitors to escape the busy life.
The temperature of the hot spring is about 51℃ to 95℃. So you can not take a bath. However, if water is added in order to lower the temperature, the advantageous effect of the hot spring become weaker. So"YuMomi" was invented.They put a plate into a hot spring and shake up it for bathers to lower the temperature so that they can take a bath.
