The demons of Japanese mythology that live in the underworld of Yomi. Yomotsu-Ikusa are employed by the guardian of Yomi, Yomotsu-Shikome, as a vast army. They are also commanded as troops by the gods of yogi. In Japanese mythology, Yomotsu-Ikusa appear as the troops sent by Izanami to pursue Izanagi as he flees Yomi. The number of Yomotsu-Ikusa sent is said to be 1,500. Just as they are about to overtake Izanagi at Yomitsuhirazaka, he drove them back by throwing a peach, believed to have demon-repelling powers. Izanagi was thus able to escape.
