Chinoike Jigoku

Bubbling up from deep underground, "netsudei" (volcanic mud) is formed through chemical reactions under extreme heat and pressure, eventually accumulating in this eerie red pond. For centuries, its ominous look has led people to call it a "jigoku" (hell). Stretching some 1,300 square meters, Chinoike Jigoku has existed for over 1,300 years and is now a well-maintained, must-visit attraction in Beppu.

The pond’s striking blood-red color comes from high concentrations of iron oxide and magnesium oxide in the volcanic mud. A hellish frame and endless burbling cauldron, step up close to see the sheer awe of nature.

Just steps away in the same area you’ll find "Gokurakutei", complete with unique dishes inspired by Chinoike Jigoku. Try the "Hell’s Paradise Curry," featuring a rich tomato-based sauce, or enjoy a beet-infused bright red soft-serve ice cream.

The souvenir shop sells an exclusive "Chinoike Ointment”, made with the same volcanic mud from the pond. This traditional skin remedy, dating back to the Meiji era, is known for its effectiveness in treating burns, frostbite, and cracked skin. Many locals in Oita have trusted this product for generations.
