Unnokuchi Castle, Mountain fortress in Nagano Prefecture, Japan.
The stone and wooden castle stands on a mountain ridge at an elevation of 1000 meters, offering views across the surrounding valleys and peaks.
The castle served as a defensive outpost during the Sengoku period, when regional lords fought for control of central Japanese territories.
The castle structure reflects traditional Japanese military architecture with its strategically positioned gates and multiple defensive perimeters.
The mountain location requires visitors to follow a marked hiking trail through forested slopes to reach the castle grounds.
The castle position at this altitude makes it one of the highest elevation fortresses constructed during medieval Japan.
