Chinoike Jigoku.
Chinoike Jigoku, or "Blood Pond Hell," is a must-visit hot spring in Beppu, Japan, celebrated for its striking red water, heated to a scalding 78°C. This unique thermal pool, rich in iron oxide, creates a surreal atmosphere reminiscent of mythological underworlds. With a history spanning over 1,300 years, it has witnessed dark events, once serving as a site where victims were tortured. Today, it captivates visitors with its eerie beauty and offers health benefits through its mineral-rich mud, known for its healing properties for skin ailments. Guests can enjoy free foot baths in cooler water and purchase skincare products derived from the mud. As one of the "hells" on the Beppu Jigoku Meguri tour, Chinoike Jigoku marries chilling history with modern wellness, making it an unforgettable attraction.
