[Unazuki Onsen]
Unazuki Onsen was opened in 1923 on a terrace 200 meters above sea level at the entrance to the Kurobe Gorge. The hot spring water was drawn about 8 km from the upstream Kuronagi Onsen (96°C), and is a simple spring with a temperature of 60°C. It developed along with the development of power sources on the Kurobe River, and is now the base for sightseeing in the Kurobe Gorge.
