Some springs are far too hot and too chemically aggressive to bathe in, and for a thousand years people called those jigoku: hells.
Umi Jigoku is cobalt turquoise at around 98°C, and the colour is dissolved iron sulphate rather than any dye. Chinoike Jigoku is deep red from iron-rich clay and is the oldest natural hell documented in Japan. Tatsumaki is a geyser on a roughly half-hourly cycle, with a stone slab set over it to hold the jet down.

Umi Jigoku (turquoise, from dissolved iron sulphate at about 98°C) and Chinoike Jigoku (deep red from iron clay, the oldest documented in Japan) are the two that differ most. The combined ticket at around ¥2,200 only pays off if you visit four or more.
No — that is what makes them hells. They are too hot and too chemically aggressive, and the circuit is for looking. Bathing happens at Takegawara Onsen, at Myoban, and at around a hundred neighbourhood bathhouses that charge ¥100–300 and have no staff.
