Shimo-Akasaka Castle

Shimo-Akasaka Castle is a mountain fortress in Chihayaakasaka built on Mount Kabutori with multiple fortified enclosures arranged along the ridgeline, taking advantage of the natural slope and elevation changes. The site incorporates the hillside itself as a defensive element, with each level positioned to control approaches to the stronghold above.

Built in 1331 during the Genko War, the fortress served as a key stronghold for Kusunoki Masashige's resistance against the Kamakura shogunate. It was part of a larger network of defensive positions that connected regional forces and allowed coordinated military operations across multiple territories.

The site reflects a time when local leaders used mountain strongholds to resist centralized power, showing how terrain itself became a tool for independence. Today, this choice of location and its role in a broader network reveals how medieval communities organized their defenses across entire regions.

The main enclosure is now occupied by the village administrative building, while a commemorative marker can be found at the nearby junior high school grounds. Visitors should prepare for steep pathways and changing elevations given the mountain location, particularly when weather conditions are wet.

The fortress featured a system of movable bridges that connected it with nearby Kami-Akasaka Castle, allowing coordinated defenses between the two strongholds. These bridges could be quickly raised or destroyed during attacks, creating a flexible defensive arrangement across the mountainous terrain.
