Nagashino Castle

Nagashino Castle is a medieval fortress in Shinshiro where stone walls and earthen ramparts rise at the point where the Toyokawa and Uren rivers meet. The site spreads across several levels with visible foundations of the main fortification and smaller defense lines.

Suganuma Motonari built the castle in 1508 to control the river crossing and secure regional trade routes. The site became the stage for a major clash between rival warlords in the 16th century, reshaping the political map of the region.

The site once served as a military stronghold and now sits quietly at the meeting point of two rivers. Visitors can walk through the remains and experience how terrain and waterways together formed a natural defense.

The site is a seven-minute walk from Nagashino-jo Station or about ten minutes by car from the Shinshiro interchange. Comfortable shoes are advisable because some paths cross uneven ground with slopes.

The Iida Line tracks now cut straight through the former castle grounds, separating the main fortification from the outer defense rings. Trains pass through the historic site several times a day, giving the place an unusual mix of past and present.
