Good point - I was referring more to the greater fleet of which the Yamato was the first, the UNCF - United Nations Cosmo Force. It was mildly implied in the first series, but later on, with Yamato II (Comet Empire) naming the Borodino battleship, Hood battle cruiser and Lexington carrier. Then it was even more particularly shown in Yamato III (Bolar Wars), you had battleships from all different nations showing up including the Prince of Wales, Bismark and, yes, Arizona. Such internationalism is more prominently shown in the new Yamato 2199 series. But you're right, the Yamato crew by itself is majority, if not all, Japanese in origin.
