Umashiashikabihikoji is a kami. According to the Kojiki, he came into being as a hitorigami early in the creation of the universe. He was the fourth kami to come into existence and the first to have a gendered name. The tale in the Kojiki states he came into existence from something like reed shoots that sprouted forth from oil drifting like a jellyfish when the land was young. He was preceded by Kamimusubi and followed by Ame no Tokotachi.
