My approach with Japan the two games I’ve played has been to build IC in India and FIC, build Arm there, and build TRNs also to keep a steady flow of Inf from Japan to Persia. That puts a lot of pressure on Cau to allow either Germany or Japan to take it. Once you have a big Axis presence in Cau, that Sink IC becomes less valuable to the Allies.
In other words, go around it - to the south. Germany can take Cau a lot sooner if Japan is in a position to immediately reinforce with a bunch of stuff.
My tourney game I also faced Russian defence (but no IC) and was also not able to take Sink / Yakut until J5 or so, but still there was enough money that I had 2 ICs and 7 TRNs running. I think Japan’s priorities should be building TRNs, taking Australia / New Zealand / India ASAP (J3) and picking up all the island Inf. Japan’s TRNs practically pay for themselves because of the island Inf supply, and because they increase the value of your forces by moving them to the front much faster.
Haven’t actually faced that American IC in Sink though.
Submarine have to face a round of fire from the attacking aircraft, then, if it has not been hit, at the end of the round it can submerge.
All Submerged submarines resurface at the end of the turn of the power in which turn they had been submerged. Example: UK aircraft attack a German submarine and miss. The German submarine then submerges. The submarine resurfaces at the end of the UK turn.
So the best way to counter the Australia IC is to b**** out?
No really though, I understand. Thats kind of a good strategy for any nation though, just a bit hard to execute because Japan is spread out through islands.
Australia is an awesome naval base that gives the Allies a great deal of freedom in the Pacific. But either US or the UK must come to the fight with some naval units. While they build naval units, Japan and Germany press the attack on Russia.
Japan’s position degrades very quickly after Australia gets going, but it is almost impossible for the Allies to capture Japan itself. Far before Japan is in any real danger (with a stack of infantry and fighters on it), Germany and Japan should be able to make Russia fall. From that point, it’s really Japan and Germany vs. UK and US. In a 9 VC game, that means that Germany and Japan together have a deathgrip on 8 VCs (all in Europe and mainland Asia, probably including India, Karelia, and Moscow), but have probably lost the Phillipine Islands.
Since Japan cannot be broken, and Germany cannot be broken, the victory should go to the Axis, with a navy and air force fueled by Russian IPCs, and a positional advantage that allows Germany to threaten London itself as well as threatening Africa and Brazil with only minimal IPCs invested.
Of course, the Allies are not locked into defending Australia, but any IPCs spent there are IPCs not used elsewhere in those important early turns.
