Today, we went to Kusatsu Hot Springs. It is located in the mountains of Gunma Prefecture in the town of Kusatsu. The volcanic hot springs is known for having the largest volume of hot water flow in the country, more than 32,000 liters of spring water gush out of the mountain per minute. The result is a town that seems engulfed in steam. All the rivers run warm or even hot. The acidity (sulfur, aluminum sulfite, and chloride) and minerals in the water leave a colored trail alongside. It is a sight to see.

Can you tell how green this hot river flow is?
One of the most acidic in all hot springs of Japan, Kusastu claims that its waters can cure just about any illness, from muscle pain to high blood pressure to diabetes. As the famous song says, everyone must come to Kusatsu Onsen at least once in their life. I am sure I soaked some ails away but the temperature of our outdoor bath was so hot, but the temperatures kept us from staying too long.
The heat of the hot springs not only cures tourists of ailments but the hot water is harnessed for use in heating the town. It is also the main source of heating for the town’s schools, municipal buildings, and even the streets. I am told that in the cold winter months, the abundance of this hot water under the city streets keeps them snow and ice free. Local inns and homes also use the heat energy to heat their own water and homes. They even use it to cook a local delicacy, Onsen Eggs.

In the center of town, the largest of the many springs is directed into wooden boxes. From here, the mineral deposits are cultivated. These minerals are sold in souvenir shops for visitors to take home in hopes to duplicate the therapeutic and spiritual qualities of the Kusatsu Hot Springs. We didn’t buy any so I guess we will have to return.

It was a fun day of playing, soaking, and friendship. (And, the science lesson and curing of all ails was an added bonus!)

That’s not something you can do around here.
I wonder what the Kusatsu song is like?
The town looks like a fun place to visit…..all steamy.
so many interesting things to see and learn : )
