Horikoshi Castle, Medieval castle ruins in Hirosaki, Japan
Horikoshi Castle is a medieval fortification in Hirosaki with three concentric enclosures protected by moats and earthen ramparts, featuring a circular inner bailey at its core. The layout follows classical Japanese defensive design with clearly defined zones between the protective rings.
The castle was founded in 1336 when Soga Sadamitsu, a Northern Court supporter, built a fortification at this location. Later, in 1594, it developed into a residence and administrative center under Oura Tamenobu.
A Kumano Shrine stands on the former castle grounds, linking the site's military past with local religious traditions that remain visible to visitors today. This blending shows how a military fortress and sacred space shared the same land.
The grounds are accessible for visitors to explore the ramparts and moats from various vantage points across the site. Movement is straightforward since the old earthworks and elevated areas remain clearly visible.
Archaeological excavations between 1998 and 2013 revealed numerous forge sites indicating specialized workshop production on the premises. Findings show that iron nails, armor parts, and cannonballs were manufactured here.
