Kawasoko Onsen

Kawasoko Onsen is located in Oita Prefecture in northern Kyushu, a prefecture celebrated throughout Japan as the most thermally abundant in the country, producing more hot spring water volume than any other prefecture and home to iconic destinations including Beppu with its famous eight hells and Yufuin with its mist-shrouded caldera landscape. The spring contributes to Oita's extraordinary geothermal heritage, where naturally heated waters rise from a complex system of active volcanic fissures and mineral-rich geological formations that underlie the entire Beppu-Shimabara graben zone of central Kyushu. Kawasoko Onsen offers visitors an authentic encounter with the volcanic thermal wealth of a prefecture where hot spring bathing has shaped culture, economy, and community identity more completely than perhaps anywhere else in the Japanese archipelago.
