Takakurayama Onsen—High Storehouse Mountain Spring—takes its name from a mountain whose high storehouse name suggests a geological feature of elevated storage—a peak that holds within its volcanic interior the concentrated mineral wealth that the spring draws upon, releasing the stored geological richness of the high mountain storehouse in the form of bicarbonate and carbonated mineral waters of effervescent quality. The naturally carbonated bicarbonate mineral combination delivers the lively, skin-stimulating soak of CO2-rich volcanic water, its effervescence mirroring the concentrated stored energy of the high storehouse mountain that serves as the spring's geological source and naming inspiration. This spring's high mountain storehouse name frames the geological origin of thermal spring water as the release of stored volcanic energy from the elevated reservoir of the mountain interior.
