When Ōkuninushi (also known as Ōnamuchi), the descendant (so the Kojiki) or the son (Nihon Shoki) of the god Susanoo, took upon himself the monumental task of developing Ashihara-no-Nakatsukuni, a dwarf named Sukunabikona appeared from beyond the sea and became his partner. However, after a time Sukunabikona left Ōkuninushi and went to the 'eternal land' (常世国, tokoyo no kuni). As Ōkuninushi was lamenting Sukunabikona's departure, another god illuminating the sea appears before Ōkuninushi, promising to aid him in his task if he (Ōkuninushi) will worship him. Ōkuninushi, in accordance with the god's wish, then enshrined him in Mount Mimoro (Mount Miwa) in the land of Yamato. While this god is yet unidentified at this point in the Kojiki, the version of the myth found in the Nihon Shoki has this deity explicitly identify himself as Ōnamuchi's (the default name of Ōkuninushi in this text) kushimitama and sakimitama (幸魂奇魂, 'wondrous spirit' and 'lucky/auspicious spirit', respectively). Indeed, this same passage lists 'Ōmononushi' as one of the various names for Ōnamuchi.
