Oka Castle has an extensive history. Sited on a mountaintop, it was originally built in 1185, for Minamoto no Yoshitsune.
Shiga Sadatomo took control in 1332 and made many repairs and improvements. The castle was ruled by Shiga's descendants until 1586.
At that point, it was taken over by Nakagawa Hideshige (in 1594) and more improvements were made, including an expansion. A main keep was added along with a palace. The Sankai turret (三階櫓), the castle's de facto Tenshu, collapsed in an earthquake, in 1769. Many of the buildings were destroyed by fire, in 1771, which had originated in the castle town. The Nakagawa ruled the castle until the Meiji Restoration.
