Mine Onsen, also known by the name of the public bathhouse facility, Odoriko Onsen, is a geothermal hot spring located in Daifunto park, Kawazu, Shizuoka Prefecture, Japan. The hot springs are accessible from Tokyo on the Odoriko or the Super View Odoriko train lines. [1]
Mine Onsen is part of the Kawazu hot spring system. The mineral water is high in sodium chloride and sulphur; it emerges from the source at 143°F (61.6°C). [2] There is a geyser onsite, which erupts regularly, shooting water into the air at 200°F. [3]
Thermus thermophilus bacteria has been isolated in the hot spring water. [4]
A geyser is a spring characterized by an intermittent discharge of water ejected turbulently and accompanied by steam. As a fairly rare phenomenon, the formation of geysers is due to particular hydrogeological conditions that exist only in a few places on Earth.
A hot spring, hydrothermal spring, or geothermal spring is a spring produced by the emergence of geothermally heated groundwater onto the surface of the Earth. The groundwater is heated either by shallow bodies of magma or by circulation through faults to hot rock deep in the Earth's crust. In either case, the ultimate source of the heat is the radioactive decay of naturally occurring radioactive elements in the Earth's mantle, the layer beneath the crust.
In Japan, onsen are hot springs and the bathing facilities and traditional inns around them. There are approximately 25,000 hot spring sources throughout Japan, and approximately 3,000 onsen establishments use naturally hot water from these geothermally heated springs.
