52260 Ureshino           Discovered 1982 May 22 by H. Kosai and K. Hurukawa at Kiso.
Ureshino is a city located in Saga prefecture, Kyushu island, Japan. In legend, Ureshino's name came from the Empress Jingu, who upon seeing the wounds of her injured soldiers completely healed by its hot springs, exclaimed "Ana, Ureshi" ("I am happy"). Ureshino became famous for its natural hot springs in the 8th century.
