Suko Castle, Castle ruin in Shiroishi, Japan
The stone walls of Suko Castle extend across 560 meters east to west and 580 meters north to south, featuring a double moat system.
The Ryūzōji clan captured Suko Castle in 1574 from the Hirai clan, leading to extensive renovations that transformed it into a northern Kyushu stronghold.
The castle remains represent the architectural techniques of Japanese fortification systems during the Muromachi and Sengoku periods.
Visitors can explore the preserved stone walls and earthwork fortifications while learning about the castle's role in regional conflicts.
From this castle, the Ryūzōji clan controlled five provinces: Hizen, Higo, Buzen, Chikugo, and Chikuzen, making it a center of power in Kyushu.
