Yes, it does not matter which territory the troops on the transport are invading. The amphibious assault is in the sea zone adjacent to a territory with an airbase, which is all that is required.

With the new rules it seems to me that an airbase in Korea would be the way to go every game, stationing 3 fighters in Korea and at least 3 in Japan if theres any sense that an attack on any vessels or Japan itself is imminent. That would give you an extra 6 fighters to defend SZ6. Correct me if I’m wrong.
You would need a ship in the seazone to be able to scramble all 6.
But I see no need to build the AB early, or at all, if you’ve got a good Japanese strategy, and are not under immediate/constant threat.
If there’s an amphib on Japan and no axis ships in Z6, only planes from Japan can scramble.

I did that in a game last week. Worked great. The U.K. attacked my Japanese fleet first and then a small ANZAC fleet did the same on their turn all in the same round. Wiped them all out with small losses.
