Yes, unfortunately Japan is located on the ring of fire, where there are a lot of earthquakes and volcanic eruptions in the basin of the Pacific Ocean. As “Tsunami” comes from the Japanese language, Japan have earthquakes due to the ring of fire.
But taking a look at the other side of coin, the ring of fire offered Japan to abundant hot springs across the nation !
Flowing at a rate of nearly 137,000 kiloliters per day, Beppu city in Oita prefecture is one of the most popular hot spring tourist destinations in Japan. It boasts more than 2,800 hot spring sources and high therapeutic effects.
Trying the variety of hot springs aside, there are 8 “Jigoku (literally means hell)”, scenic hot springs.
Umi-jigoku (Sea Hell)
The Sea Hell was made by the eruption of Mt.Tsurumi about 1200 years ago.
Despite its close resemblance to sea, it’s temperature is 98 degrees Celsius. Iron(II) sulfate makes it cobalt blue. Making the most of its heat, it makes boiled eggs. It’s available at a store in front of the hell.
Plus, it’s deep like sea. 200 meters deep.
Oniisi-bouzu-jigoku (Monk’s shaven head Hell)
Hotter than The Sea Hell, its temperature is 99 degrees Celsius.
The gray mud bubbles look like Buddhist monk’s shaven head, “Bozu”.
Tatumaki-jigoku (Tornado Hell)
Much hotter than that hell, it has the hottest water of all the hells.
It is one of Japan’s few geysers.
Yama-jigoku (Mountain Hell)
Unlike other hells, what you can see is steam instead of water. It might look fun, but it reaches up to 90 degree Celsius.
Siraike-jigoku (The White Pond Hell)
When hot water gusts, it’s transparent. Once it is exposed to the open air, it turns clouded. It also has a small aquarium.
kmado-jigoku (Cooking Pot Hell)
A red “Oni” demon statue is standing on a cooking pot called “Kamado”.
In this hell, you can see 6 different hot springs. For example, a cobalt blue spring, gray mud spring and steaming spring.
