Tennen Onsen (Kaze no Mori), in Oyabe, Toyama Prefecture, offers sodium-chloride water at 41°C, with an indoor bath, an outdoor bath (rotenburo) and a sauna on site.
Insider tip — Kaze no Mori, the wind-in-the-forest spring, serves Oyabe City at the southern gateway of the Toyama plain where the Shogawa River descends from the World Heritage gassho-zukuri villages of Gokayama. Oyabe was historically the transportation center for the silk and lacquerware trade descending from the isolated mountain communities of the Shokawa valley — merchants carrying Nishida-Shirakawa lacquerware and hand-spun Gokayama silk crossed the Oyabe ford to reach the coastal markets of Fushiki Port on Toyama Bay.
