Is UKPac at risk of breaking out? Will you be able to actually take it with those tanks? If not, infantry/art, keep shucking more guys south via transport. Or mechs to save money over tanks if you still want fast movers.
Option #1 If UKPac isn’t breaking out, 2 more carriers. Japan’s greatest asset is its many, many planes. Use them. 32 ipcs gives you 4 more planes to attack with. Take Philippines fleet north, Malaya goes to Philippines, Sumatra fleet heads up to FiC which gets a naval base. That base let’s you reach Japan in 1 move, but also makes the transports worth while to bring guys south. If you won’t need to keep going back and forth with the transports, it’s still useful for bring all 6 transports into your Calcutta attack.
Make sure the FiC fleet is just big enough to safely sink anything ANZAC has right now. Then you’ll have 6 carriers in your attack fleet and can annihilate anything the U.S. has or they retreat or they spend 100% of their IPCs on Pacific which is what Germany wants, too. After that any navy spending is just subs to soak hits or bombers for their reach.
You’ve got 6 transports that can take more troops South to FiC for 6 more on the mainland every turn plus the 6 you can build.
If Japan wanted to help out Germany, hit Russia, not South Africa. By the time you reach S. Africa, UK can easily have it well defended and for not much cost. Japaneses bombers in China can hit Moscow. More Japanese troops in the north and you can do a full invasion of Russia, Mongolia be darned.
On the next turn, Philippines fleet can join Japan, they can all go to Caroline Islands to force U.S. to choose whether to help ANZAC or not. You should have enough to destroy them all, though, so the U.S. retreats. Not all your fleet goes south to ANZAC. Just enough to stay afloat, some planes to help take it. Bring a few transports. New Guinea can be taken to use for bombers. Get a naval base as quick as possible down there.
But, mostly, go for the win with Japan.
