Odawara Castle

小田原城

Reconstructed buildings

Odawara changed from the Hojo clan’s regional stronghold into an Edo-period castle. Its rebuilt keep and reconstructed gates introduce changes in both scale and function.

THE STORY

The story behind the walls

The medieval castle grew into the Hojo centre of rule in the Kanto region. A perimeter around the town was prepared before the 1590 campaign, which ended in surrender. Later lords reshaped the castle during the Edo period. After the keep was dismantled in the Meiji era, reconstruction began with the present keep in 1960 and continued with gates and bridges.

LAYOUT & ARCHITECTURE

Read the landscape and the buildings.

Distinguish the Hojo’s broad outer circuit from the later main and second enclosures. Moats, masonry and gateways define the routes through today’s park. The reconstructed keep represents a later castle form, not an unchanged medieval Hojo stronghold.

A CLOSER LOOK

Details worth a closer look.

01

Keep rebuilt in 1960

The present keep is a postwar reconstruction. Its displays help visitors connect today’s park with the castle’s different historical phases.

02

Following the gates

Reconstructed gates include Tokiwagimon, Akaganemon and Umadashimon. Passing through successive entrances helps explain the later castle’s defences.

03

The wider defensive circuit

The Hojo created a defensive perimeter enclosing the town as well as the castle. This wider circuit extends the story far beyond the present keep.
