Second Floor
The second floor was used as the armory (bugu no ma). The floor plans of the first and second floors are very similar, with a central area surrounded by a wide corridor. The central area on the second floor is a single room lined with original wooden shelves on three walls where weapons were stored.
There is also an exhibit featuring the five Japanese castles whose main keeps have been designated as National Treasures. Along with Inuyama Castle are photographs of Himeji, Matsumoto, Hikone, and Matsue castles. Inuyama Castle’s main keep is considered to be the oldest among them. A wooden model of the structure of the keep showcases the intricate detail involved in its timber construction.
