Matsumoto Castle
Inuyama Castle is located on a hill overlooking the Kiso River in what is now the city of Inuyama. Inuyama Castle is often claimed without any historical justification as the "oldest castle in Japan"; however, Inuyama Castle is one of 12 castles to have retained its Edo period "Tenshukaku" intact. This main tower is small but due to its complex form, it shows different silhouettes depend on the angle. Among the 12 remaining main towers, the "tenshu" at Inuyama Castle is designated as a National Treasure of Japan, as are Matsumoto Castle, Hikone Castle and Himeji Castle.
