Kumo no Mukou, Yakusoku no Basho: Relations between the United States and Japan are so extremely bad that the USSR can simply annex Hokkaido in 1974 without anyone lifting a finger to stop it. Also somehow the USSR possesses enough advanced technology to build what can only be described as a massive space elevator in the middle of Hokkaido. Tower that manages to consume the entire island. Although it does not matter much, because the United States, for reasons never clarified, has started World War III by directly attacking the Soviet Union.
YU-NO: A Girl Who Chants Love at the Bound of this World, or just Yu-no (I refuse to put the name in Japanese, it's stupidly long): Japan, and maybe the world, uses a different number system than Arabic, and apparently there are cycles of catastrophes every 400 years. It is also possible that the Japanese are partially beings from another damn dimension.
War of the Worlds. Humanity now has plenty of new alien toys, mostly military gear, to disassemble and reverse engineer. As well as the knowledge that aliens are out there. And they are aggressive. And the only thing that can protect us from them is biological warfare.
Battleship. The fact that the United States and Japan have managed to contain an alien invasion should lead to less suspicion that Japan is arming itself, and the popularity of the Missouri would skyrocket around the world.
