THE STORY

The story behind the walls

The Sagara clan based itself in Hitoyoshi in the medieval period and continued to rule through the Edo era. The early-modern castle is understood as an expansion of a medieval hilltop stronghold, with added walls and grounds. A major fire in 1862 caused extensive damage. Although the buildings are gone, enclosures and masonry retain its plan. Conservation following the 2020 floods continues, including riverside wall works in 2026.

LAYOUT & ARCHITECTURE

Read the landscape and the buildings.

The site lies south of the Kuma River, with the Mune River to the west and hills to the east and south. The main enclosure occupies the high ground, with the second and third enclosures stepping down towards the foot. Some walls have projecting upper stones known as musha-gaeshi, making their masonry form a notable feature.

A CLOSER LOOK

Details worth a closer look.

Surviving stone walls

Substantial masonry remains along the riverside part of the castle. Details include upper projecting stones known as musha-gaeshi.

Stronghold of the Sagara clan

The site records the history of the family that governed the region for centuries. Its remains connect the medieval hillfort with later stone-walled development.
