Wakamiya Iriyama Castle
Further up from Aratojō and Aratoshōjō are the ruins of Wakamiya-Iriyamajō. I believe Wakamiya-Iriyamajō is so called to distinguish it from another castle called Iriyamajō some distance south. Wakamiya-Iriyamajō has a single principal bailey but also some minor baileys and koshikuruwa (hip baileys) terracing the mountain slope beneath it. There are also the remains of horikiri (trenches), particularly, most interestingly, in between large boulders that cling to the mountain ridge. Indeed the castle seems to have been built with using rocky outcroppings as part of its defences.
Climbing above Wakamiya-Iriyamajō will take one to Shōjō. There is a flat part of the ridge between the two sites with what may have been eathworks, and this may have been an extension of Wakamiya-Iriyamajō. Noticing this, I photographed them, but I was unsure. This flattened area may have been used as a garrison point between the two forts.
