One of the greatest hot springs in Japan
Our most important feature is our 100% natural hot spring. It is a treasure from Mt. Zao and the earth.
Because the temperature of the headspring is so high (58℃ :136.4°Ｆ), we take reduce the temperature to around 40℃ for the baths. The hot spring is rich in minerals.
Gaga Onsen is considered one of the top three hot springs in Japan for curing stomach and intestinal illness, along with Yunohira-Onsen and Shima-Onsen.
A samurai discovered Gaga Onsen over 140 years ago
It is said that Gaga Onsen might have been created sometime between 834 and 847AD，when Mt. Zao was an active volcano. Sometime between 1847 and1853, a hunter named Rokuji discovered the hot spring.
Time passed. Tokiyasu Takeuchi from Gunma Prefecture visited here in 1872 . He realized it was a divine spring and opened a hotel with official permission in the 1879 after much difficulty. He named it Gaga Onsen.
