Kobozu Jigoku - “Young Priest Hell”
Fumaroles, mud pots and hot springs abound in this area known as Kobozu Jigoku (Young Priest Hell). Some are so loud they can be heard from far away. The mud here is a pale gray rather than the usual darker color, due to the low levels of iron sulfide and sulfur in the escaping steam. The temperature of the mud hovers around an extremely hot 94°C. In the distance, you can see reddish-brown earth created by iron-rich hot spring sediment. On the south side of the road, visitors can spot large, active mud pots.
