The spring water is volcanic in origin, filtered through the layers of the Aso caldera.
The water is classified as soft, mineral-rich spring water with a neutral pH.
A portion of the water flow is used locally for irrigation of surrounding rice paddies.
The Shirakawa Yoshimi Shrine located on-site is dedicated to the water deity.
The spring basin remains remarkably clear, allowing visibility to the sandy bottom where water bubbles emerge.
Shirakawa Spring is a primary source of the Shirakawa River located at the base of Mount Aso in Minamiaso. The site features a natural pool with a discharge rate of approximately 60 tons of water per minute. The spring water is renowned for its constant temperature of 14 degrees Celsius year-round. It is designated as one of the '100 Famous Waters of Japan' by the Ministry of the Environment. The water is considered potable, and visitors can drink directly from the spring. Surrounding the water source is a cedar forest with wooden pathways and small bridges. A Shinto shrine, Shirakawa Yoshimi Shrine, sits within the grounds near the water source. The area remains a popular destination for those seeking water purification and geological interest.

Avoid wading into the water, as the spring is a protected water source and drinking supply for the local community.
Respect the sanctity of the on-site shrine by maintaining a quiet demeanor; do not throw coins directly into the main spring pool.
