Taira Fureai Onsen Center (Yu-Raku), in Nanto, Toyama Prefecture, offers bicarbonate thermal water at 40°C, with an indoor bath, an open-air outdoor bath (rotenburo) and a sauna for visitors.
Insider tip — Yu-Raku at Taira Fureai serves Nanto City at the gateway to the Gokayama UNESCO World Heritage thatched-roof village cluster in the upper Shogawa valley. The Taira district of Nanto was historically one of the most isolated communities in the Japanese Alps — accessible only by river gorge trails until the 1980s — and this isolation preserved not only the distinctive gassho-zukuri architecture but also a unique 800-year-old tradition of hand-woven Gokayama washi paper designated an Important Intangible Cultural Property of Japan.
