A large scale model of the castle and the samurai town below it circa 1840 gives you something to compare the modern town with, and provides a much better idea of the scale and grandeur of the castle in its heyday. Wall presentations of antique scrolls display the elegance of castle town life and of those of the lords of the castle.
　　　　
Items from samurai life passed down from the Lords of Inuyama Castle, including art works, samurai arms and armor, also local crafts and special temporary exhibitions keep the museum fresh and fascinating. See earthenware and Inuyama pottery, old maps and manuscripts. There are rooms displaying the local Karakuri Dolls, mechanical puppets that performed atop the huge festival floats, also on display.

Once you've gained some knowledge of the castle town of Inuyama, and its important place in Japanese history, you'll be fully armed to tackle the town!
