About

Oniishibozu Jigoku is a set of pools of thick grey hot mud that blister up into round domes before bursting with a soft plop, which is why they were likened to the shaven heads (bozu) of Buddhist monks. It is quieter and more intimate than its neighbour Umi Jigoku, with walkways through a mossy garden, a free foot bath and the Oniishi no Yu bathhouse attached (separate fee), so you can soak after viewing. The mud pools are hypnotic: stand still and wait for the next bubble.

Highlights

Tips

Covered by the 7-hell common ticket
Walk 1 minute from Umi Jigoku; visit them back to back
Video works better than photos to capture the bubbles
The bathhouse is a good option if you want to soak mid-tour
