Gero Hot Springs (Gero Onsen)
The historic hot spring “Gero Onsen” is said to have been discovered in the Engi era (901-923) and the Tenryaku era (947-957). During the Edo period, a Confucian scholar who served the Tokugawa family, Hayashi Razan, noted the hot spring as one of "the three famous springs in Japan," alongside Arima Onsen in Hyogo Prefecture and Kusatsu Onsen in Gunma Prefecture.
In the summer evenings after dinner, the streets around the hot springs are filled with travelers strolling around in yukata.
