This is one of Takeda Shingen's secret springs, where it is said the Kai Province warriors healed their wounds after a fight.
Established about one hundred years ago, Shibu Tatsunokan has been a pilgrimage destination for people seeking to cure their ailments at its "miraculous" baths.
The free-flowing onsen water pumped directly from the spring source naturally reaches 20 degrees. You can experience soaking alternatively in the cold bath, where the water is left to its original temperature and the heated bath.
