Magokusa Onsen is a bicarbonate and carbonated thermal spring in Oita Prefecture's Kokonoe Town—part of the Kuju highland volcanic landscape that constitutes one of Japan's most exceptional concentrations of volcanic springs, where the Kuju volcanic group's extraordinary geothermal activity drives springs of diverse mineral character across a high-altitude plateau of grasslands, wetlands, and volcanic geological diversity. The effervescent, skin-stimulating quality of naturally carbonated bicarbonate waters provides a lively mineral soak within a highland volcanic setting of considerable natural beauty, where the same geological forces that produce Oita Prefecture's world-leading hot spring volume and variety also drive the CO2-rich effervescence of this Kuju highland spring. The Kuju highland position gives Magokusa Onsen access to one of the most geothermally active and botanically rich volcanic plateau landscapes in all of Japan.
