About

In the heart of Beppu, where the earth's veins pulse with primordial heat, there lies a spectacle both mesmerizing and formidable. This is the "Blood Pond Hell," a natural hot spring that has captivated and awed visitors for over thirteen centuries.

The pond's surface is a vivid crimson, a hue born from the depths of the earth. Beneath the surface, high temperatures and pressures orchestrate a natural alchemy, producing iron oxide and magnesium oxide. These minerals infuse the emerging mud with a deep red color, painting the pond in shades reminiscent of ancient myths. The waters, heated to approximately 78 degrees Celsius, bubble and steam, releasing a mist that carries the scent of minerals and the whispers of the earth's inner workings. (beppu-jigoku.com)
