This hot spring is known for having both radium springs and thorium springs. Generally, radium springs are suitable for bathing, while thorium springs are cold springs. The radium used in the radium sheet is from the radium spring, which has a very mild nature and no extreme stimulation, making it safe for anyone to use.

Radium-containing hot spring water is said to be effective for the Hormesis effect, far-infrared effect, negative ion effect, and improvement of atopic dermatitis.

[Introduction to Futamata Hot Springs (Hokkaido)]
Futamata Radium Hot Springs in Hokkaido is a rare hot spring that erupts with limestone sinter. It is said to be one of only two such locations in the world, the other being the Mammoth Hot Springs in Yellowstone National Park, USA.

The limestone domes were designated as a Hokkaido Prefectural Natural Monument and have been protected since June 1965. Furthermore, in 1982, the yu-no-hana deposited by the hot spring was recognized by the Ministry of Health, Labour and Welfare for its efficacy and effectiveness as a bathing additive for general household use, and was approved as a quasi-drug under the Pharmaceutical Affairs Law for commercial sale.
