Yeah, do what these guys say. Also, consider that Transports (TRs) are a better value dollar-for-dollar than an IC & Armor (ARM) for Japan, at least until you’ve got much of Asia under your belt. Put INF en masse onto the continent each turn & as alamein says, use your Fighters (FTRs) as ARM. But FTRs are better than ARM in movement & defense so be sure to deploy them defensively after your attack. Sink the USA Hawaiian Islands fleet 1st turn…
I am not a big fan of attacking India 1st turn if the Allies have built up there. Even w/ 3 INF, 1 FTR & 1 TR there you are in for a stiff fight & will expose yourself to Chinese spoiling counterattacks. Thats why IMHO its important to concentrate on loading INF to the continent using TRs the 1st few turns until you can put an IC on Asia. Due to the fact that UK is wholly dependent on their 3-point IC in India for troops, using INF, FTRs & w/ the addition of an IC for ARM, you ought to be able to bottle up UK until you are so strong you can crush them without fear of a counterattack. Now UK feels like a big idiot 'cuz they wasted 15 IPCs on an IC + who knows how much on troops only to be annihilated with no effect on the game.
Most important–work with your Germany player. I can’t stress this enough–if the player layout is as you describe (sounds like the best player is the UK player & the USSR & USA players are known to play aggressive early on) I’d suggest you & your partner meet well before the game & discuss strategy while you still have time. Develop a combined plan of action & stick to it. Talk frequently during the game to coordinate your moves. Germany & Japan must cooperate not just strategically but tactically (move for move) in order to win a game like this…
Hope this helps!
