Einōsan Castle, Korean-style fortress in Saijō, Japan
The ruins extend across 720 meters from north to south and 470 meters from east to west, with stone walls measuring 2.5 kilometers in length.
The castle emerged in the 7th century following Japanese military losses at the Battle of Hakusukinoe in 663, during concerns about invasions from Silla and Tang China.
The architectural design reflects Korean fortress influences, marking a departure from traditional Japanese castle construction methods of that period.
Visitors can reach the castle site within 10 minutes by car from Iyo-Miyoshi Station on the JR Shikoku Yosan Line.
Archaeological surveys revealed granite cut stone rows and evidence of blacksmithing activities, though specific details about castle gates remain unknown.
