Arashiro Onsen (Ebisu no Yu), also in Takayama, Gifu Prefecture, heats bicarbonate water to 40°C, with an indoor bath, an outdoor bath (rotenburo) and a sauna.
Insider tip — Ebisu no Yu serves the eastern residential quarter of Takayama City, Japan most celebrated Edo-period merchant town where three-century-old machiya townhouses line the Sanmachi Suji district in one of the best-preserved historic streetscapes in all of Asia. Takayama was governed directly by the Tokugawa shogunate as tennryo (government territory) from 1692, a status that paradoxically protected its historic architecture from development and gave the city the nickname Little Kyoto of the Mountains — a comparison its spring and autumn Furukawa Festival processions richly justify.
