Aoyama Castle

History

The history of Aoyama Castle is not well known but it was obviously a part of the defensive network of Ueda and Uesugi clan castles. It is mentioned in the writings of Ota Dokan as being one of the strong fortifications, along with Koshigoe Castle, in the area.

Visit Notes

The trailhead for this castle is not easy to find. Please look at the map of photos and find the photo of my bicycle. This is the sign in front of the trailhead. It's on a very small road that arcs from the main road. The north entry point of this road is a very small path that doesn't even look like a road. It's probably easier to go to the southern end of this arc and find your way up the small hill to this sign and the beginning of the trail. At first you'll need to follow the signs for Sengenyama (仙元山) until the trail splits and you see an obvious sign that points to the castle (right) and the mountaintop (left). Using the same directions (without photos) I was unsure of myself on the trail and almost doubled back at one point. Just follow the main trail until you see the sign for the castle.

From the mountaintop I discovered there is also a trail leading off to Ogura Castle. It would be fun to follow the mountain top over to Ogura Castle sometime too.
