Kobayakawa Hideaki
This castle was attacked by Kobayakawa Hideaki after the Battle of Sekigahara. The castle surrendered at half a day though the brother of Mitsunari, Ishida Masazumi and his father Ishida Masatsugu , defended it. Afterwards, Ii Naomasa occupied Sawayama Castle. However, he destroyed it, and moved to Hikone Castle. Much of Sawayama Castle's stone walls and buildings were carried away for use in Hikone Castle. At present, the only indication of this old history is a sign reading "The Site of Sawayama Castle."
