Château de Gankaiji

The castle structures integrate defensive features into the mountainside terrain, utilizing stone walls and wooden buildings for strategic protection.

Built during the Sengoku period, the castle served as a military stronghold to control access routes through the region's valleys.

The architecture follows traditional Japanese castle construction methods, incorporating watchtowers and multiple courtyards within its defensive perimeter.

The castle site requires a 30-minute walk through mountain paths from the nearest parking area, with limited access during winter months.

The castle's position at 36.7 degrees latitude provides clear views of both the Northern Japan Alps and Toyama Bay on cloudless days.
