Imazu Onsen, in Nishinomiya, Hyogo Prefecture, not far from Osaka, offers sodium-chloride water at 41°C, along with an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Imazu Onsen serves the Imazu coastal district of Nishinomiya City on Osaka Bay where the ancient Imazu port served as Kyoto commercial gateway before the development of Osaka harbor. Nishinomiya is the heart of Japan most celebrated sake production region — the Nada area of Nishinomiya and neighboring Kobe accounts for nearly 30 percent of Japan total sake output, using the uniquely mineral-rich Miyamizu spring water from the Rokko mountains to produce the most highly rated sake in Japan, and Koshien Stadium in Nishinomiya is Japan most sacred baseball venue.
