Discovered on 19 January 1998 by Shimizu, Y., Urata, T. at Nachi-Katsuura.
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.Naming citation (20000320/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
