Château de Hachioyama

Château de Hachioyama is a mountain fortress in Gifu Prefecture positioned on a steep mountain ridge. The location commands broad views over surrounding valleys and the old routes that once connected the region.

The fortress was built during the Sengoku period between 1467 and 1603 as a military outpost. It monitored mountain passes and served as a key defensive position during this era of conflict.

The ruins show traditional Japanese building methods, with stone walls that adapt to the natural mountain shape. The foundations follow the terrain and create a connection between the structure and the landscape.

The path to the ruins climbs through a forested mountain and requires sturdy walking shoes. Bring plenty of water and allow extra time for the steep terrain.

The stone walls were built without mortar, with massive boulders fitted precisely together. This ancient technique has kept the structure stable across the centuries.
