Usui Castle

Usui Castle is a fortified site on a plateau overlooking Inba Marsh, with earthen ramparts, moats, and distinct defensive zones marking its medieval layout. The remains reveal how the settlement was organized to protect itself against attack.

The site was founded in the 12th century and passed through the hands of several clans before being abandoned in the 17th century. It saw conflict and changing control during the period of feudal competition in the region.

The site layout shows how defenders once positioned themselves to control access to the surrounding wetlands. The earthen mounds and moat traces reflect the practical concerns of medieval rulers in this region.

The site is a 20-minute walk from Keisei Usui Station, reached by following local signs through residential streets. Wear sturdy shoes, as the terrain on the plateau is uneven and can be muddy in wet weather.

The tomb of a warrior named Sukemune Ota sits atop the earthen ramparts, marking where he died during a lengthy siege in 1479. This burial place stands as a quiet reminder of the violence that once gripped this hilltop.
