Ruins & historic sites

Maeda Toshinaga’s retirement castle survives as Takaoka Kojo Park, with much of its moat system intact. Water boundaries and connecting earth bridges are the key to understanding it.

THE STORY

The story behind the walls

Toshinaga built the castle and developed its town in 1609. After his death in 1614, the one-castle policy led to abolition in 1615. Under Maeda Toshitsune, the town was reorganised around commerce and industry while the castle’s moats and banks remained. Local preservation efforts helped establish a park in 1875.

LAYOUT & ARCHITECTURE

Read the landscape and the buildings.

Several forward enclosures surround the main bailey and are linked by narrow crossings. Water separates the spaces while controlled bridges connect them. The surviving moat lines allow the defensive plan to be studied even without its buildings.

A CLOSER LOOK

Details worth a closer look.

01

Surviving wet moats

The moats remained largely unfilled after the castle’s abolition. Looking across the water makes the enclosure boundaries clear.

02

Linked forward enclosures

Forward enclosures around the main bailey protected entrances and supported counterattacks. Their earth-bridge connections are central to the design.

03

From castle town to trading town

Storage and other uses continued after abolition as Takaoka became a commercial and industrial town. The castle’s short life contrasts with the city’s long continuity.
