Hirosaki Castle

弘前城

Original keep

The Tsugaru clan’s castle retains an Edo-period keep, turrets and gates. Beyond its famous spring setting, its moats and enclosures reveal how the compact keep fitted into a much larger castle.

THE STORY

The story behind the walls

Tsugaru Nobuhira carried forward Tamenobu’s plans and completed the castle in 1611. Lightning destroyed the first five-tiered keep in 1627. The current keep was built in 1810 under Tsugaru Yasuchika, after a long period without one. Recent work conserves both the main-enclosure walls and the historic keep.

LAYOUT & ARCHITECTURE

Read the landscape and the buildings.

Moats divide the enclosures and gates control movement between them. The present keep has three roof tiers and three storeys, with more elaborate gables on its outward-facing sides. Its simpler inner faces reveal a different architectural emphasis.

A CLOSER LOOK

Details worth a closer look.

01

The 1810 keep

The surviving keep is a later building, not the original five-tiered tower. Its decoration differs between inward- and outward-facing sides.

02

Turrets and gates

Three turrets and five gates survive alongside the keep. Their positions help explain entrances and corner defences across the castle.

03

Conserving the stone walls

The keep has been moved as part of stone-wall and conservation work. The preservation process is an important part of the castle’s present story.
