Château de Kozashijo

Kozashijo is a Japanese castle in Fukushima Prefecture built on a strategic hillside position. Stone and wooden structures, defensive walls, and multiple guard towers overlook the surrounding valleys.

The castle was built during the Sengoku period when Japan consisted of many independent states needing fortified positions in mountainous areas. It was part of the military network supporting these warring powers.

The structure displays traditional Japanese military design with wooden gates and stone foundations adapted specifically for mountain terrain. Visitors can observe these architectural choices while exploring the remains.

The site can be accessed through marked mountain paths with information panels explaining the historical layout. Sturdy footwear and extra time for exploring the uneven terrain are recommended.

The fortress incorporated the natural slope of the hillside as part of its defense system, showing how builders adapted the structure to local geography. This integration reveals the builders' practical understanding of terrain advantages.
