Oumi Aoyama Castle
Aoyamajō was built as a satellite fortification of Ogurajō by the Ogura Clan. Search Oumi Ogura Castle for more information. The site is now forest and tanuki nesting grounds.
Aoyamajō is a forested earthworks castle ruin in Higashi-Ōmi. It is a hirayamajiro type, gakejiro subtype castle, meaning that the castle was built overlooking a steep change in elevation – a cliff – on one side, and on its three other sides where the terrain was flat earthen ramparts were heaped up and dry moats dug. These earthworks have lasted well, with the dorui (berms) going all around the shukuruwa (main bailey) except where it borders the cliff side, and deep karabori (dry moats) making the castle ruins quite clear. The karabori become tatebori (climbing moats) where they meet the cliff line and fall. The shukuruwa is now rather over-grown. I found many tanuki (raccoon-dog) burrows dug into the ramparts, and, sure enough, a tanuki appeared nearby.
