Kinojo (Mt. Kinojo / Ogre Castle)

鬼ノ城（鬼城山）きのじょう きのじょうざん

On a 400-meter peak above the Soja Plain stands a castle that history forgot to record. For some 2.8 kilometers, a band of rammed-earth wall and stone rings the summit of Mt. Kinojo, pierced by four great gates and six water gates — yet not a single line about its building survives in the Nihon Shoki or any other chronicle. Excavations point to the late 7th century, most likely raised by the Yamato court to guard against a feared invasion after Japan's catastrophic defeat at the Battle of Baekgang in 663. But it is the legend, not the archaeology, that gives the place its name and its chill: this was the lair of Ura, an ogre said to be a Baekje prince, who terrorized the land of Kibi until the hero Kibitsu-hiko cut him down — a story scholars read as the memory of Korean ironworking immigrants clashing with central power, and the very seed from which the tale of Momotaro grew. Today the reconstructed west gate rises white and stark on its rammed-earth platform, banners of red and white along its eaves, the plain spread out far below. Few ancient mountain castles in Japan let you walk this fully restored line of walls — and fewer still come haunted by an ogre.
