This fort was built as a "tsume-no-shiro" (mountaintop fortress to flee to when under siege) for the Hikobe Yashiki. I assume it was also built around 1561 by Hikobe Nobukatsu, who built the Hikobe Yashiki, but have found no details either way.
Please refer to the Hikobe Yashiki for more information.
It seems that there are a couple of trails to the top of the mountain. The route I took started from the Kamo Shrine. This bilingual guide to hiking trails shows a walking course that includes the Hikobe Yashiki. Pay attention to the signs along the course however, because the route to the fort at the top of the mountain branches from the main trail. Even in March it was still overgrown with trees and shrubs, not to mention a number of fallen trees to climb over/around to get to the top. Regardless, there really isn't anything to see. It would be nice if they trimmed back the trees around the top. I'm sure you would get nice views of the area.
