Nishikawa Castle (西川城 Nishikawa-jō) was a branch castle of the Saigo Clan in the Mikawa region during the Age of Warring States in Japan. The name Nishikawa means west river in Japanese.There are no extant structures on the site of the castle though alterations to the topography such as earthen ramparts and a dry moat are readily apparent and an explanatory signboard is posted by the trail leading up to the main courtyard.
