Minowa Castle

Minowa Castle is a mountain fortress in Takasaki, Japan, spread across a hill at the ridge end of Mount Haruna. The site includes multiple tiers of stone walls, earthen ramparts and dry moats extending across a broad terrain.

The Nagano family built the site in the early 16th century and used it as their main base to control the region. After a long siege by enemy forces, the fortress fell and later lost its military role.

The name refers to the Nagano family, who held power here for generations and controlled the surrounding territory. Today visitors can walk along the earthen ramparts and follow the defensive lines that once kept attackers at bay.

The ruins sit in a wooded setting and require sturdy footwear, as paths can be uneven. Visitors planning to explore all the defensive lines should allow enough time and bring water.

The site ranks among the largest of its kind in Gunma Prefecture and was added to a nationwide list for its military importance. Some sections of the moats and ramparts remain well preserved and offer insight into medieval defense strategies.
