Yoshino Chiku Kasseika Center (Yoshino Onsen) is located in Shinshotsugawa, on the Ishikari plain in Hokkaido. Its sodium-chloride water flows at 42°C, pH 7.3. The site has an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — Shinshotsugawa-cho was founded by settlers from Totsugawa, a remote mountain village in Nara Prefecture, who colonised Hokkaido in 1889 after floods destroyed their Yoshino homeland. The Yoshino Onsen community centre honours this remarkable migration story, connecting the descendants to the Yoshino cherry blossom heritage of ancient Yamato Japan.
