Yudanaka Station is a railway station in the town of Yamanouchi, Nagano, Japan, operated by the private railway operating company Nagano Electric Railway. Yudanaka Station is a gateway to seasonal mountain and outdoor activities, including hiking and skiing or snowboarding, and to Jigokudani Monkey Park where Japanese macaques soak in an outdoor hot spring.
An indoor Japanese hot spring named Kotonoyu is located in the former station building, standing beside the current station. The former station building itself is registered as tangible cultural property.
