An ancient fort in Japan has been invaded by cats.

Inuyama Castle, situated on a small hill overlooking the Kiso River, was built as a military stronghold by Oda Nobuyasu, uncle of Shogun Oda Nobunaga. During the Edo period, Naruse's faction captured the castle and ruled it until the Meiji period.

According to the Meiji-era castle demolition decree, Inuyama Castle was largely dismantled, except for the tallest tower, the watchtower, and the castle gates. The remaining parts of the castle were severely damaged by the Great Chubu Earthquake of 1891. After many years, Aichi Prefecture returned the castle to the Naruse family, its former owners, on the condition that they would "restore and maintain Inuyama Castle." As of 2004, Inuyama Castle was the only privately owned castle in Japan.

Inuyama (犬山) in Japanese means "dog mountain," so Inuyama Castle is also known as "dog mountain castle."

But recently, these "invading" stray cats have been constantly trying to break into and occupy the castle. Like many ancient Japanese fortresses, Inuyama Castle has small openings in its walls so soldiers could fire arrows if necessary. However, these clever cats have turned it into a way to break into the castle.

Cats are very popular animals in Japan. They are considered sacred animals, bringing good luck to the Japanese people. Therefore, the invasion of stray cats on the "dog mountain castle" has become a humorous event, attracting the attention of netizens. A debate has erupted over whether cats will soon become the rulers of the castle, and whether it will be renamed the "cat mountain castle."

In Japan, there are also many areas where the "residents" are mainly cats, such as Aoshima Island, Enoshima Island, Tashirojima Island, etc.
