Bluegill was brought to Japan in 1960 as a food fish by then Crown Prince Akihito who received it as a gift from Chicago, IL. In 1963, the Fisheries Agency sent bluegill to Lake Biwa. Ten years later, bluegill had spread all over the lake. In 2007 in Shiga, Emperor Akihito expressed regret over bringing the bluegill.
