THE STORY

The story behind the walls

The Asakura established their power in Echizen around the Onin War and ruled from Ichijodani for five generations. They gathered senior retainers in the valley and developed a town and cultural centre. Defeat by Oda Nobunaga in 1573 ended their rule and brought destruction to the town. Excavated remains and reconstructed buildings now help explain this lost medieval settlement.

LAYOUT & ARCHITECTURE

Read the landscape and the buildings.

Residences and streets occupied the narrow valley, while defensive enclosures used the mountain behind it. Changes in elevation separated everyday urban life from fortified refuges. The reconstructed streets represent archaeological work on houses and town planning, not a rebuilt castle keep.

A CLOSER LOOK

Details worth a closer look.

01

The Asakura residence and gardens

Building foundations and garden stones outline life at the lord’s residence. They represent government and hospitality, in contrast to the defensive mountain above.

02

Reconstructed townscape

Samurai residences and town houses have been reconstructed using excavated foundations and walls. A roughly 200-metre street lets visitors compare domestic and working spaces.

03

Valley and mountain

The mountain castle worked together with residences and a town below. Treating the valley walk and mountain hike as separate routes makes this large site easier to understand.
