Château de Daikoji

Daikoji Castle is a medieval fortress on a small hill in Aomori Prefecture in northern Japan with multiple defensive sections and surrounding moats. The ruins stand about 600 meters from Hiraga Station and are marked by informational panels and commemorative monuments.

The Soga family built the fortress in 1333 during the Kamakura period to establish their presence in northern Japanese territories. This founding was part of political consolidation in the region during a time of major feudal changes.

The north gate of Hirosaki Castle, called Kikkomon, preserves architectural elements from Daikoji's original entrance. This connection shows how builders reused materials and design features across centuries.

The site is in gently hilly terrain and is reachable on foot from Hiraga Station, with pathways clearly marked by signs. It is advisable to wear sturdy shoes as the ground is uneven and the layout of the fortification invites exploration.

The fortress was divided into three distinct sections: Daikoji Furudate, Daikoji Itsuka-ichitate, and Daikoji Shinjō, each reflecting different development phases. This division allows visitors to compare different periods and construction methods directly on site.
