Kuroba Onsen is located in Gokayama, part of Nanto city in Toyama Prefecture, an area known for its traditional gassho-zukuri houses. Its sulfurous thermal water emerges at 42°C (pH 6.5), with an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Nanto city encompasses the legendary Gokayama (五箇山) UNESCO World Heritage villages — remote mountain communities of gassho-zukuri thatched-roof farmhouses, some standing 300-400 years beneath crushing winter snowloads. Gokayama was so isolated that it sheltered defeated Taira clan survivors after the 12th-century Genpei War, and later housed political exiles under the Kaga domain. Kuroba Onsen's sulfurous waters warm visitors arriving via the steep mountain passes — a reward after navigating the winding roads to one of Japan's most authentically preserved historic landscapes.
