Azuchi Castle

安土城

Ruins & historic sites

Oda Nobunaga’s castle survives as stone approaches and hilltop remains. Broad steps and residence sites explain its planning as well as inviting questions about the lost keep.

THE STORY

The story behind the walls

Nobunaga began construction in 1576 and moved into the completed keep in 1579. After his death in the Honnoji Incident of 1582, the keep and main enclosure burned. The site briefly retained significance for the Oda family before losing its role around 1585. Archaeological research and conservation continue to clarify its design.

LAYOUT & ARCHITECTURE

Read the landscape and the buildings.

Stone walls and steps connected the hillside residences, main approach and summit precinct. Routes branched beyond the broad entrance avenue, with gates controlling access to the centre. The lakeside setting mattered, though historic shorelines should not simply be equated with today’s landscape.

A CLOSER LOOK

Details worth a closer look.

01

The broad main approach

The straight section of the main approach is about eight metres wide. Stone borders and drainage channels help explain its formal, carefully planned character.

02

Retainer residence sites

Terraces beside the approach are traditionally associated with Hideyoshi and Maeda Toshiie. Distinguish those traditional names from the building layouts established by excavation.

03

Keep platform and main enclosure

Foundations and walls remain around the summit keep platform and main enclosure. These remains provide a starting point for understanding why reconstruction drawings differ.
