Ibaraki, Osaka
Ibaraki-dōji (茨木童子 or 茨城童子 "Ibaraki child") is an oni (demon or ogre) featured in tales of the Heian period. In the tales, Ibaraki-dōji is based on Mount Ōe, and once went on a rampage in Kyoto. The "Ibaraki" in his name may refer to Ibaraki, Osaka; "dōji" means "child", but in this context is a demon offspring. Ibaraki-dōji was the most important servant of Shuten-dōji.
