Yamashiro Onsen is one of the Kaga region’s oldest hot spring towns, its waters discovered some 1,300 years ago according to local tradition, and the town today centres on Kosoyu, a beautifully restored public bathhouse rebuilt in the style of the Meiji-era original, alongside the still-functioning Soyu bathhouse next door. The town also has strong ties to Kutani porcelain, one of Japan’s most celebrated ceramic traditions, with a small museum and shops nearby offering a look at the distinctive, richly coloured pottery style associated with the region.

Tips
Kosoyu and Soyu are separate bathhouses next door to each other, each with a small entry fee, so budget for trying both if time allows rather than assuming one covers the other. Many visitors combine a soak with an overnight ryokan stay in town, which typically includes access to private baths as well as the public bathhouses.
