For the Allies to build ICs in Asia they have to have a very strong foothold in the first round.
2 transports + infantry in round 1
With Russia restricted its usually preventable.
You can leverage a lot of airpower, the transport in the Phillipines. The Bomber goes inland as long as much airpower and infantry as you can bring to bear. Pearl Harbor isn’t vital, helps if you can disrupt it a bit, but I wouldn’t worry about it too much. Hit it with a light attack using whatever is left over and expendable after your mainland attack. You may want to leave the battleship and the aircraft carrier towards the coast one off of Japan, and one off of wherever you decide to land reinforcements for that region. If they have too much airpower you may want to consolidate them, but this costs time.
I wouldn’t draw from the islands (except the Philipines on round one) just make sure your transports can consolidate in the sea of Japan for the infantry wave that starts on round 2. The allies will spend a lot of resources keeping any foothold they get once they build those factories. Unless you are really unlucky you will knock them out. As the other poster suggested, Germany will benefit from the redirection of effort.
It will cost you some time, but don’t worry about the Northern territories in Russia just yet. The opening moves should give their intent away, so just hammer them early. Once dug in they will cost Japan a lot of time.
They are difficult to mop up and your reinforcements from the Main Island should be able to hold them back until you have resources free to deal with them. You want to deny the allies the opportunity to dig in. If russia reinforces heavily, Sinkiang may be out of reach.
Make sure you don’t leave your fighters vulnerable to counter attack, you will need them to support your infantry if you can’t get them early. Its just a matter of time until you overrun them if you use your troops judiciously.
In the interim be aggressive with Germany. A legitimate threat with a strong mix of tanks will keep their troops on the front, and they will have less support than usual. If they draw to much into asia, count them up and consider an offensive against them, or a strafe.
If you put a lot of pressure on the factories they will have to buy fighters to defend them and it will eat a lot of their units. If they get a fighter stranded, attack it with low value units or a lot of fighters so you increase the chance of a favorable trade.
If you need America to slow down on their builds you can send a transport out and pick up a troop or two within striking range of their coast. They will have to build defensively… if they go light enough on defense take the gamble and land them. It will tie up the transport but the IPCs they have to spend to protect an attack from hawaii affects the quality of what they can put in the factory.
