The "Beppu Jigoku (Hell) Tour," which takes you through seven unique jigoku (hells), is a classic Beppu sightseeing experience. The scenes of steam, hot mud, and boiling water erupting from deep underground truly resemble hell.

The tour includes seven jigoku (hells): Umi Jigoku, Chinoike Jigoku, Tatsumaki Jigoku, Shiraike Jigoku, Oniishi Bozu Jigoku, Oniyama Jigoku, and Kamado Jigoku.
