Kōri-Nishiyama Castle

Kōri-Nishiyama Castle is a medieval fortress ruin in Koori featuring three distinct main areas that formed the center of the installation. The layout reveals how the different sections once functioned together as a cohesive defensive system.

The fortress was established in 1532 as the seat of the Date clan, then abandoned in 1548 following clan disputes. This shift ended its role as a major regional power center.

The ruins hold meaning as a landmark of samurai heritage and were once central to regional power. Today, festivals and local gatherings keep the memory of this military past alive in community events.

Entry points are available from two parking areas with easy access to the main sections. Information panels throughout the grounds help orient visitors as they explore the different zones.

The natural Sagasawa River curves along two sides of the site, serving as a built-in defensive barrier. This natural feature was integral to how the location was strategically chosen and defended.
