This is a relatively new facility that was opened in February 2008 and is gaining reputation due to its good spring water quality. It is frequented by locals to enjoy a relaxing time. A resting area is provided, where guests can purchase lunch boxes and bread. The spring is a bicarbonate salt spring, not often found in Usa, and its iron component crystalizes forming the so-called "yu-no-hana" . The brown and thick spring water will warm the core of your body. It is well-known for its beneficial effects on the skin and can be a substitute for skin lotion. Both the male and female baths have both indoor and outdoor baths.
