Its strategic location along the Kiso River made it a key defensive and transportation point.
Role in Early Modern Japan
During the Edo period, the castle came under the control of the Naruse family, who served as feudal lords under the Tokugawa shogunate. The castle remained an important regional stronghold and administrative center.
Unlike many castles that were destroyed or heavily altered, Inuyama Castle survived largely intact through centuries of political and social change.
