Umegashima Konya Onsen is located in Aoi Ward, Shizuoka City in the mountainous upper valley of the former Suruga Province, where it forms part of the Umegashima Onsenkyo cluster alongside Umegashima Onsen and Umegashima Shinden Onsen, embedded in a rural landscape of scattered vacation cottages and farmhouses known for its light winter snowfall and pleasantly cool summer temperatures. The spring flows with sulfate and simple thermal waters classified as one of Shizuoka Prefecture's finest alkaline springs, producing colorless, transparent water with a subtle sulfurous aroma and the gentle skin-conditioning properties associated with naturally alkaline mineral water of the type known in Japan as bijin no yu. Umegashima Konya Onsen's combination of its pristine alkaline mineral water, mountain highland setting, and year-round moderate climate — making it as appealing in summer as in winter — contributes to the distinctive character of one of Shizuoka's most quietly beautiful and thermally rewarding hot spring valleys.
