Interrupted field castle Jinya

Jinya is an incomplete fortress in Tarui with a rectangular layout and defensive features limited to its eastern side. The structure features stone walls and moats that follow Edo period design principles, though its restricted fortifications set it apart from full castles.

The Takenaka clan constructed this structure in the 16th century after the Edo Shogunate forbade them from building full castles. This restriction led to a new architectural approach that combined administrative headquarters with partial defensive capabilities.

The castle reflects how regional lords lived under the Shogun's control, adapting their residences to restrictions that prevented them from building true fortifications. Visitors can see how this limitation shaped both the design and the daily life within these walls.

The entrance gate remains accessible and currently serves as the entry to a local educational facility. Visitors should note that the grounds are in active use, so access may vary depending on the institution's schedule.

The structure was never intended as a true fortress but rather as a residential compound with minimal defensive features, making it a rare example of this adapted building type. This approach shows how regional leaders cleverly navigated political restrictions imposed on them.
