Morimoto still has true Japanese A5 Wagyu on their menu. $28 an ounce, minimum 3 ounce serving.
To confirm what gharter posted above, aside from Takumi-Tei everything else marketed by Disney as Kobe Beef is most likely coming from Snake River Farms, a domestic producer crossing Japanese Wagyu with Black Angus cattle. Snake River does produce some excellent cattle but it's closer to Prime Beef than it is to Japanese Wagyu and prices out at roughly 1/4 to 1/3 the price of the real thing.
