Inuyama Castle (犬山城, Inuyama-jō) is a hirayama-style Japanese castle located in the city of Inuyama, Aichi Prefecture, Japan. The castle overlooks the Kiso River, which serves as the border between Aichi and Gifu Prefectures. The tenshu of Inuyama Castle, one of only 12 pre-modern tenshu remaining in existence, has been determined to be one of the oldest remaining tenshu, although Maruoka Castle also makes this claim. The castle has been a National Historic Site since 2018.
