Tsuyama Castle

津山城

Ruins & historic sites

Tsuyama Castle is an early modern fortress whose tall stone walls rise in successive layers around a hill. Although most buildings have disappeared, its stepped enclosures still convey the scale of the castle.

THE STORY

The story behind the walls

Mori Tadamasa arrived in Tsuyama in 1603 and began construction in 1604. Work continued for about thirteen years until 1616, developing both the castle and its town. The Matsudaira family later held the castle, but the keep and other buildings were removed in the Meiji era. The ruins became Kakuzan Park, where conservation centres on the surviving stone walls. Reconstruction of the Bitchu Turret in 2005 restored one part of the lost building complex.

LAYOUT & ARCHITECTURE

Read the landscape and the buildings.

A central enclosure occupies the hilltop, surrounded by second and third enclosures. Tall stone walls and turning passages through gates prevented a direct approach to the centre. Comparing the former keep site with the Bitchu Turret helps distinguish a prominent landmark from buildings associated with the palace.

A CLOSER LOOK

Details worth a closer look.

01

A castle outlined in stone

Ninomaru and Sannomaru surround the central enclosure, with stone walls creating substantial changes in level. Looking back during the ascent reveals several defensive lines rather than one continuous barrier.

02

The reconstructed Bitchu Turret

The Bitchu Turret was reconstructed in 2005 and is distinct from the former keep. Its rooms once connected with the palace’s private spaces, showing that a turret could also serve residential functions.

03

Connections with the castle town

The Mori developed the surrounding town alongside the castle. Exploring its streets after the stone precincts helps connect the hilltop defences with the community at their foot.

BEFORE YOU GO

A note before you go.

Exploring the enclosures involves climbing stone steps. A visit inside the Bitchu Turret differs from a walk through the park, so include its opening arrangements when planning to see the building.
