This was a satellite fortification of Hiyama Castle. Refer to Hiyama Castle for more details.
Archeological excavations of the site reveal artifacts of an early fortified manor and artifacts dating to the 800s. It may have been a fortification or base of the Emishi in the Gangyo Rebellion of 878.
Ohdate is about 5.5km north of Hiyama Castle. It is basically one large bailey at the top of a hill. It was sectioned off by some embankments and trenches but through weathering or high weeds, unfortuantely, I could not make out any of them. There are a couple small signs along the road pointing out the castle but once you get there, there is only one small sign that has rotted through and fallen down into the weeds near the trailhead. The view from the distance is probably best and gives you a good understanding of the strategic importance of this site near the entrance of the valley to Hiyama Castle.
Ohdate is a National Historic Site combined with Hiyama Castle and Chausudate
