48575 Hawaii           Discovered 1994 July 4 by A. Nakamura at Kuma Kogen.
Hawaii, the Aloha State, was first visited by Polynesians from Tahiti, rediscovered by James Cook, and in 1959 became the fiftieth U.S. state. Hawaii became a sister state of Ehime prefecture, after the fatal accident in 2001 when a U.S. Navy submarine struck a fisheries training ship from Ehime off Hawaii.
