Spoiler:

It seems odd though that the Japanese would need a ton of landing ships to invade their own country by sea -- has there been a large contingent of Japanese hiding out on the Chinese mainland, waiting for their time to head back to Japan and invade maybe? Thats the most plausible thing I can think of. Kyushu IS an island, but with all the flight carriers that Britannia has to drop Knightmares, I don't think it would be that much better than invading Honshu.
