Kojimajō is said to have been first built by the Anekōji Clan in the Nanbokuchō Period. In that civil war Kojimajō was used by southern court supporters. In the Sengoku Period Kojimajō was occupied by the Kojima Clan but was obliterated by Kanamori Nagachika in his conquest of the area in 1585.
I had no plan to visit Takaharasuwajō that day until I learned about its history in connection with the fortified manor house of the Ema Clan, the Ema-yakata. It is physically removed from the yakata, however, and only one of many such castles in the area of Kamioka town. Since a mountain road goes directly by the castle ruin it is possible to drive there, although there's only space to park by the entrance to the trail head for a single vehicle. Castle ruins are apparent immediately as the trail starts. Here there is a double trench system with buddhist statues scattered here and there. Another horikiri (trench) linked to an incredibly long tatebori (climbing moat) running the height of the mountain is located before the central bailey, which has more climbing moats around it. The central bailey is almost entirely surrounded by a ring bailey, which I liked. Ascending to the central bailey itself gives a brilliant view of the valley below, especially of the reconstructed Yakata. The mogi-tenshu at Kamiokajō is also visible from here.
