Beppu Benten Pond is a mysterious pond located in the area called "Beppu" in Mine City, Yamaguchi Prefecture. It was formed by groundwater from the karst plateau springing up, and the color of the water is particularly noteworthy. It is characterized by beautiful, highly transparent spring water that changes from cobalt blue to emerald green depending on the light and time of day. It is said that this vivid color is caused by the components contained in the limestone dissolving and scattering light, making it appear blue. The surroundings of the pond are rich in nature, and are surrounded by a pure atmosphere created by the spring water.

The water of the pond has been selected as one of the "100 Famous Waters of Japan," and you can freely draw and take it home. Many tourists bring plastic bottles or containers to taste the delicious water. There is a small shrine dedicated to Benzaiten on the edge of the pond, and it is also believed to be a power spot that brings good luck and longevity. Due to its photogenic scenery, many photos are posted on social media, and its beauty has become widely known.

There is also a water pump, and many people take spring water home in plastic bottles or water tanks.
