Oniishi Bouzu Jigoku

In Beppu, you can find the famous hells, including this one (literally Hell's Oniishi bonze), which one of the most famous for the huge grey bubbles that form (hence the name, as they resemble the bald head of a Buddhist monk) in their boiling mud pools. There is also an onsen (a hot spring) to make your feel feet great. To reach these 'hells', we have to catch a bus at the JR Beppu Station and get off at the Umi Jigoku stop. The entrance alone costs 400 yen, but its possible to buy a pass for 2000 yen to view the 5 well-known hells. To access the onsen, you have to pay 600 yen.
