10627 Ookuninushi           Discovered 1998 Jan. 19 by Y. Shimizu and T. Urata at the Nachi-Katsuura Observatory.
The mythical Japanese god Ookuninushi-no-mikoto created the land, together with the god Sukunabikona-no-mikoto. The name means "king of great land" and is a frequent reference in literature and folklore. A well-known story is that he helped a white rabbit skinned by a shark as the retribution for trickery.
