Komeiseki Onsen Fukuoka no Yu, in Takaoka, Toyama Prefecture, heats sodium-chloride water to 41°C, with an indoor bath, outdoor rotenburo and sauna.
Insider tip — Komeiseki Onsen, the luminous healing stone spring, draws from the mineral-rich aquifer of the Fukuoka district at the western edge of Takaoka where the Toyama Plain meets the coastal highlands of the Noto Peninsula. The Inami woodcarving tradition nearby has produced the most elaborate ranma transom carvings in Japan for 300 years, with master craftsmen still working in studios along the old temple road.
