Yuasa Onsen Wakayama

Yuasa, a small coastal town in Wakayama Prefecture, holds the distinction of being the birthplace of Japanese soy sauce, with the Kadocho brewery operating a traditional shoyu production facility on its historic main street since the thirteenth century, when soy sauce was first fermented on Japanese soil. Yuasa Onsen Wakayama taps chloride-rich thermal waters from the maritime geology of the Wakayama coast, offering warming baths steeped in the rich culinary and artisanal heritage of this ancient brewing town on the shores of Osaka Bay. The well-preserved historic townscape of Yuasa, designated as a Japan Heritage site, with its sake breweries, merchant houses, and narrow stone-paved lanes, creates a uniquely atmospheric backdrop for thermal spa exploration on the Kinki coast.
