The main tower of the castle
The word "inuyama" literally translates from Japanese as "dog mountain." The castle has the second name “Hakutei Castle” (“The White Emperor’s Castle”)  , this name was given to the castle by the scientist Og Soray. 
It is believed that the foundation of the castle was laid back in the 1440s .  The main towers of the castle were built in 1537 by Oda Nobuyasu.
In 1891, the castle was badly damaged by an earthquake. In 1895, the Japanese government decided to return the castle to the heirs of the Naruse clan to maintain it in good condition. 
In 1965, the castle was dismantled for overhaul. After studying the wooden beams, it was found that the two lower floors of the castle were built much earlier than the upper. [four]
Inuyama Castle belongs to the flat-mountain type of castles. Consists of three external tiers, four internal floors and two basement floors.  The design of the castle was greatly changed - modern towers were built in 1537 . In 1617, the third tier was completed.  The main tower ( tenshu ) is made in the style of the Azuchi-Momoyama era .
On the ground floor there are barracks for the daimyo army. They are divided into four rooms, surrounded by a circular corridor from which the sentry can monitor the situation. The second floor is an armory for storing a reserve of weapons and armor , and on the third floor there are personal premises. From the observation deck of the upper tier of the castle overlooks the city of Inuyama and the Kiso River. [five]
