Jiho Onsen is an onsen (Japanese hot spring bath) located in Nagaoka, Niigata. The water emerges at around 41°C. The site includes an indoor bath, an open-air bath (rotenburo) and a sauna.
Insider tip — Jiho Onsen is located in the Nagaoka area of Niigata Prefecture on Japan's Sea of Japan coast, where saline waters are characteristic of the coastal lowland geology. Niigata is renowned for heavy snowfall (yukiguni or snow country), making a warming soak in saline onsen waters especially appealing during the long winter months. The sodium-chloride waters here are said to improve circulation and leave skin notably smooth. Nagaoka also hosts one of Japan's largest fireworks festivals each August, making summer visits particularly festive.
