Origin of Gero Onsen

Gero Onsen is said to have originated in the Enki era (901-923 A.D.).
The reason why it is called one of the three most famous hot springs in Japan is because the Confucian scholar Hayashi Razan, who served four shoguns including Tokugawa Ieyasu, said, "There are many hot springs in Japan, but the most famous are Arima, Kusatsu, and Yushima (Gero). Arima and Kusatsu are widely known to the public, but few people know that Yushima has been a sacred hot spring since ancient times. However, those who have taken a bath in Yushima have never failed to have luck.
In fact, the Muromachi period poet priest Banri Shu-ku had already written that Kusatsu, Arima, and Yushima (Gero) were the three most famous springs in Japan, and it is thought that the Confucian scholar Hayashi Razan quoted this description.
At that time, it was still called "Yushima", not "Gero".
Our hotel, located in "Yunoshima," which still remains as the name of the place, has been waiting for your visit as "Yunoshimakan" since 1931.
In any case, the fact that Gero Onsen was located in the mountains, where it was difficult for people to enter, shows that it has been called a famous spring since ancient times.
