THE STORY
The story behind the walls
Tradition traces the castle to the Utsunomiya clan’s Jizogatake stronghold in the late Kamakura period. Early-modern lords including Todo Takatora and Wakisaka Yasuharu developed the castle. The old keep was dismantled in 1888, but four turrets survived. Photographs and a wooden structural model later provided evidence for reconstruction. A wooden keep was completed in 2004 and can be viewed alongside the historic turrets.
LAYOUT & ARCHITECTURE
Read the landscape and the buildings.
The keep and turrets occupy a hill beside the Hiji River. The four-tiered, four-storey keep was reconstructed in wood using an Edo-period structural model and old photographs. Its connections with surviving turrets show how new reconstruction was combined with historic buildings.
A CLOSER LOOK
Details worth a closer look.
Timber-reconstructed keep
The keep was reconstructed in 2004 using historic photographs and a timber model. Recreating its wooden structure, not only its appearance, distinguishes this keep.
Four surviving turrets
Four surviving turrets, including Daidokoro and Koran, are Important Cultural Properties. They are surviving historical structures, unlike the newly reconstructed keep.
