It is a rare high-concentration radon hot spring in Japan, and its spring quality is a weakly radioactive bicarbonate spring, known as a "therapeutic spring." It is said to be effective against neuralgia, muscle pain, poor circulation, and chronic skin diseases, and to support health from the inside of the body. In addition to the spacious indoor bath, there are two types of open-air baths, a Japanese style and a Western style, with different styles for men and women, which are switched every week. The greatest attraction is that you can enjoy a relaxing bath while watching the scenery of the Hiruzen Plateau in each season.

The building is also equipped with a variety of facilities such as a sauna, jacuzzi, and cold bath, so you can refresh yourself in various ways. There is also a kids' playroom so that children can enjoy it with peace of mind. After the bath, soft ice cream is also popular, and a cool sweet treat will provide a pleasant moment for your body warmed by the hot spring. The facility is also proud of the beautiful gardens that the gardener has carefully designed, and a stroll after the bath is recommended.

It is the perfect place to stop by after leisure or sports on the Hiruzen Plateau, or on the way to drive, to relieve the fatigue of your travels.
