History
{{Main|Siege of Katsurayama}}
The Katsurayama Castle was built during the Sengoku period of Japan. At around 1557, Baba Nobuharu, one of the "Twenty-Four Generals of Takeda Shingen" decided that he was going to siege the castle. His plan fully went into action in March 1557 when him and 6,000 samurai and ashigaru succeeded in destroying the castle and killing the castle garrison.
