Joyo Onsen

Joyo Onsen is a community thermal facility in the city of Joyo in the southwestern corner of Kyoto Prefecture, a modern city in the Yamashiro basin whose flat terrain along the Kizu River has been continuously inhabited since the Yayoi period (300 BCE–300 CE) and whose name—meaning 'prosperous castle'—recalls the medieval strongholds that once controlled this strategic river crossing at the southern approach to the ancient capital. The mineral thermal waters offer warm, relaxing sodium chloride immersion for a dense residential community straddling the administrative boundary of Kyoto and Osaka prefectures, where the commuter culture of the Kintetsu and JR Kinki lines connects the ancient capital with the modern metropolitan network. The nearby Uji River headwaters and the southern Kyoto tea country give this thermal facility a quiet geographic resonance at the historical southern threshold of Japan's cultural heartland.
