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.
Chinoike Jigoku and Umi Jigoku actually have totally different vibes. The contrast between the red and blue is really striking, and the visual impact is pretty direct and impressive.
