Ninomaru

Kuruwa is about 30 meters wide and 30 meters long. Building traces were confirmed by excavations, and the current pavilion was built based on those traces. Excavated items include Chinese celadon, white porcelain, Seto ware, and large Bizen ware pots.
If you look in the direction of Ninomaru from the southeast side, you can see the steep cliffs that have been processed into the cut bank, and it is built to keep out attackers.
