母畑溫泉, Radioactive hot spring in Ishikawa, Japan
Located near Lake Bobata, this hot spring contains the highest radium concentration in Japan's Tohoku region. The mineral-rich water is used at several facilities and attracts visitors seeking therapeutic bathing experiences.
The spring was discovered roughly 900 years ago when the warrior Minamoto no Yoshiie used the water to heal wounded horses during military campaigns. This early use established a reputation for healing that later extended to human visitors.
The spring water flows through several traditional inns along the Kitasu River, where visitors bathe in the Japanese manner. Many guests come here to experience the healing properties that locals have valued for centuries.
The spring is reachable by car in about 15 minutes from Fukushima Airport IC via the Abukuma Kogen Road. Visitors should plan their trip knowing the facilities remain open throughout the year, with each season offering something different.
The water can be consumed directly as well as used for bathing, with a traditional practice of drinking it to address conditions like diabetes, gout, and digestive issues. This dual use sets it apart from typical hot spring facilities in the region.
