The spring water is categorized as soft water with a high level of mineral purity.
It is identified as a 'cold spring' because it emerges from underground at a constant temperature regardless of external air changes.
The basin is known for its high transparency, allowing clear views of the aquatic vegetation and rocks at the bottom.
The surrounding woods are part of a protected ecosystem designed to maintain the purity of the groundwater recharge zone.
Shiogama Cold Spring is a natural spring located at the base of Mt. Kamihiruzen, designated as one of the 100 Famous Waters of Japan by the Ministry of the Environment. It produces approximately 300 liters of water per second, which maintains a constant temperature of 11 degrees Celsius throughout the year. The spring is the source of the Kuga River and is situated within the Daisen-Oki National Park area. The surrounding landscape features a lush forest of Japanese beech and Katsura trees that turn vibrant colors in autumn. Visitors can view the emerald-green basin directly via a wooden walkway system built over the water. It serves as a vital water source for the Hiruzen highland region, supporting local agriculture and tourism.
