The castle was damaged by the Great Nobi Earthquake in 1891. The castle was then given to the Naruse family under the condition that they repair the castle. The castle is the only privately owned castle in Japan (The Naruse family formed foundation, the foundation owned now). The castle survived all wars and has remained unchanged since it was built, making it the oldest original wooden castle in Japan.
