Amphibious combat move

That’s correct.

You said “build land troops in FIC”: is this on J2?  Because you’re not allowed to place a factory in a newly captured territory, correct?  So are you putting the minor IC in Manchuria or Kiangsu (one of the 3 IPC territories)?

A declaration of war step in the sequence of play right before combat moves might have been a good idea with the exception being the US Automatic DOW.

@fanofbond:

Can a jap transport move through an allied controlled seazone?
While i’m on the subject of questions can us planes land in either Anzac or uk  territories before the dow.

If Japan is at war with any of the allies in the sea zone, and there’s a ship that you can’t ignore, then the answer is no.

If Japan is not at war with any of the allies in the sea zone, but will be by the end of Japan’s turn, and there’s a ship that you can’t ignore, then the answer is no.

Japan can move past allies it is not at war with, to attack allies it is at war with, provided none of Japan’s moves will result in war with the moved through power.

The answer to your second question is no. US planes can only land in US territories or on US Carriers, when it is not at war.
