U-511 was the first U-boat to travel from Germany to Japan, and was handed over to the IJN who renamed it RO-500. But it doesn't seem to have actually done anything in Japanese service, apparently it was just given to the IJN so they could study Germany submarine technology. Still, the IJN connection would make it more likely than most U-boats, I'd think.
