This Castle amounts to the Koriyama Moutain whole mountain located the north of the Yoshida Basin sandwiched between Kawai River and Tajihi River. Original Kooriyama Castle is a small castle of the fort degree, it was the same as the Castle of the kokujin ryoshu (local samurai lord) and gozoku (local ruling families), there was not the big change until 1523 when Motonari Mouri entered this Castle. Motonari plans the ecdysis from a leader of kokujin ryoshu to the Sengoku Period Daimyo, and expanded the Castle area in the whole Yoshidakoriyama Mountain. For the remains of an ancient structure of the castle, more than 270 Kuruwa existed in a ridge and the supporting ridge and valley region that spread radially from the mountaintop part of approximately 390m above sea level. The complicated territory that put plural ridges together is the characteristic that is greatly different from the castle of other the kokujin ryoshu.
