The castle was once thought to be the home of Mori Motonari's half brother but that is not clear. It was most likely a satellite castle of Koriyama Castle. It was also the base for Sue Takafusa at the Battle of Koriyama.
You can see a couple embankments and small trenches here. There is no map or sign pointing to the castle but there is a slight trail you can see from across the road by the sign about the castle. Follow the trail up and you'll find the ruins easily.
Funayama Castle and Tenjinyama Castle are two minor satellite castles around the side of Koriyama Castle (Hiroshima) at the end of a ridge connecting to Koriyama Castle. A kiritoshi, or road was cut away through the mountain ridge at this point and a small castle was built on either side of it for the Battle of Koriyama. I did not know about these castles until I visited the Akitakata City Museum. I had run out of time to visit Goryu Castle, so I walked the 1km over here around the side of Koriyama Castle to visit Funayama Castle and Tenjinyama Castle next to it.
