Suhara Onsen sits in Yuasa, Wakayama Prefecture, where sodium-chloride water flows at 41°C. An indoor bath, an open-air rotenburo and a sauna make up this Kansai-region bathhouse, a relaxing stop after a day of sightseeing.
Insider tip — Suhara Onsen serves Yuasa Town, the birthplace of Japanese soy sauce where Zen monk Kakushin returned from China in 1254 and began producing kinzanji miso from which shoyu naturally dripped — the liquid became the seasoning that transformed Japanese cuisine. The Yuasa kurabito brewery district with its white-walled fermentation warehouses is a UNESCO heritage townscape, and Yuasa shoyu is still produced using 700-year-old techniques in the original quarter.
