Gero Onsen
Gero Onsen is a historic hot spring said to have been discovered either during the Engi era (901-923) or the Tenryaku era (947-957). Records indicate that Oda Nobunaga was particularly fond of the hot spring and often visited for therapeutic bathing. During the Edo period, Hayashi Razan, a Confucian scholar who served the Tokugawa family, named it one of Japan’s Three Famous Hot Springs, 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.
