This spring shares geological features with Arima-Onsen in Japan, which ranks among that country's most significant thermal waters. These similarities reflect deep geological processes that created comparable mineral springs across different regions.
Local residents have long valued this spring for its mineral-rich composition, which has earned it cultural significance in the community. Visitors can see the distinctive yellow coloring of the water, which reflects the iron and other minerals that define the spring's identity.
Visitors should expect mineral deposits to form on surfaces in the area due to mineral-rich water exposure to air, creating visible yellow crystalline formations. The facility is easy to navigate, with clearly marked public areas and separate private rooms for your bathing choice.
When the mineral-rich water dries in the air, it leaves behind bright yellow crystalline deposits that visitors often call hot spring flowers. These formations accumulate on surfaces around the spring and serve as a visible reminder of the water's mineral content.
