Masuzawa Castle

Masuzawa Castle stands on a ridge extending from Mount Kasadzu, featuring stone ramparts and terraces cut into the hillside with dry moats and earthworks demonstrating mountain castle design.

Built by the Azumune family during the Muromachi period, the castle served as a strategic fortress controlling transportation routes between inland areas and coastal regions until the late 16th century.

The castle exemplifies typical mountain castle architecture in northern Japan, representing the defensive strategies and construction techniques adapted to mountainous terrain during the feudal period.

Archaeological excavations have revealed layers of earthworks and building remnants, while the site now functions as a designated historical park with informational signage for visitors.

Local legends describe the castle as a meeting place for secret samurai councils and military strategists, highlighting its role in regional political intrigue and resistance efforts.
