I just copied and pasted this from a previous post:
Some things I do to deal with Japan (note: some options may be contradictory, as I am just listing various options that are on the table when thinking about my Asian/ Pacific affairs)
RUSSIAN OPTIONS
-
Stack Bury: Perhaps you do this only for R1 and then move them out R2, but you will notice it does constrict Japan and limits Japanese options, it also sets up a significant Russian presence quickly. This option can be helped more with other allied strats going on to limit Japanese options. Also notice, this costs Russia no IPC’s (though it can cost a turn in positioning units)
-
China pump: Try pumping in 1-2 inf per turn into China. Will only be useful in conjunction with other strats. If you are doing NOTHING else to stop Japan, you may be wasting units.
-
Airforce: Buy 1 or 2 fig, make sure they are on either Mos or the Cau. This can open up a lot of options (I usually insist on having 1 fig on the Cau) at very little (if any cost) to your German campaign.
-
Persia/Cauc forces: Do your best to make sure you have at least 2 Russian inf on Persia. Also, try your hardest to make sure you have at least 1 Russian tank, and hopefully 1 Russian Fig on the Cau. This not only can set up a 1-2 punch on India, but it also can Relieve the Brits from worrying about Italy holding Jordan. Notice outside of the 2 inf, Russia is guarantying, no major unit commitment in Asia and Russia still has major units geared up against Germany.
-
Move Russian Far Eastern Forces to China: This will put stacks of Russians in Asia at no expense to Russia. It will take a couple turns to have a significant presence, and you will be giving up (very cheap) ground in Russia, but it is good for a cheap long term strategy. Bonus: if necessity demands, due to the forces already being moved in that direction, the troops can be used to ward off Germany. Also, if you have air in Moscow (or Cau) they can be used for counter attacks or maybe even defense.
UK/US OPTIONS
- T1 United Fleet in NZ: Perhaps land 1-2 US fig in Aus instead of on the Carrier. If you wish landing 1 bomber in Aus/Hawaii would be useful as well. If you care nothing for bombers in Europe, bring the second bomber to Hawaii. The united fleet, while useful in its own right, works much better in conjunction with other Asian/Pacific theatre tactics (such as the Bury stack). The fleet can also be completely withdrawn after T1 or the (depending on the scenario) the centre piece for an allied pacific strategy (such as an Australian IC).
NOTE: If you choose to withdraw your UK transport towards America, I would suggest in most cases, to leave all UK forces in Australia and use the Canadians for transport cargo. Make the Japanese pay as much as possible for taking Australia.
- Western United States: Build 1 US transport in Western United States. This is probably fairly obvious, but it should always be done if given the opportunity, it’s a cheap build anyway and the opportunities it can provide the allies with are great. Also obvious: build naval/ air units when you can spare them (this will vary wildly depending on your strategy, main objectives, and the way the Pacific develops; I can see no way of saying how to develop a consistent US naval building strategy). Make sure to try to build 1-2 inf per turn. This is a must if any Japanese ships are within 2 turns from your cost, but you should always try and have something there just in case, and it may also lead to new opportunities in the Pacific.
3) Persia: This is usually my “center piece” for my Allied Asian strategy. Move all UK units that can reach into Persia. This assumes there is no unusual golden opportunities in Africa or building an IC that will last in India. Japan will have a supply line problem on the mainland, this will compound itself further if it chooses to build an IC or attack the Philippines J1 (I usually think attacking Phil J1 is non optimal anyway). Stacking in Persia can put Japan in a decent bind in southern Asia. If this is working in conjunction with Russian Fig and Arm in Cauc as well as Russian inf in Persia the headache for Japan grows. Add to that, other areas where the allies may be stacking on T1; Japan all of the sudden may have some hard decisions to make J2 and may find some of her theatres very hard to re-enforce. Stacking in Persia does on occasion create an opportunity for a UK3 IC in India. Also note, the Persian stack can retreat to Russia, if Russia (or the Persian stack) is in dire straits.
- United Allied Fleet in SZ 12: This too can be a centre piece when dealing with Japan. An unsinkable fleet in SZ 12 puts a threat on France, Italy, and secures Africa. Italy will most likley no longer be able to move her fleet (in fear of invasion) Germany will have to devote resources to protect France. It saves the allies money by uniting two fleets (that can be easily and safely re enforced in needed) to work on more important things. Don’t kill the Italian navy unless it is for some type of game winning deathblow (your positioning on your navy is too important) or if it is with air units that can be sacrificed.
Keep stacking N. Africa with US troops (unless going in for the kill) and every turn get 3-4 transports worth of gear for the UK and start sending them through N. Africa and March them towards India/Persia/Cauc (Armour builds for the Brits is probably a must, in order for this to be effective). Also note: Russia can join in the fun in Africa to if it has inf preventing Italy from taking Jordan. This keeps the UK’s income high, and allows it to bail out Russia if needed all the while threatening Europe with significant pressure.
-
Alternative use of bombers: If the situation allows (you have the money/ are not dependant upon a European SBR campaign/ you have a Persian stack) Fly any built US bombers to Persia. From here they can: a) Threaten the Japanese southern navy/ keep the navy “tight” b) mess with loose Japanes Trannies c) SBR Japanese IC’s in the area d) Threaten the Italian fleet. e) clear out any weak German stacks f) provide very expensive fodder for Russia if Russia is going to be attacked next turn. g) clear weak territories in China if needed e) provide a little defense for Persia (If you have 5 bombers sitting in Persia, that has to be taken into consideration by Japan)
-
Go North: If for whatever reason the US can field and send a Pacific fleet up north, do it. Perhaps Japan has moved her fleet far out of position not expecting it. Perhaps you somehow are diverting Japans resources to other areas, whatever the reason, if you can start a successful campaign up north, do it. It will pressure Japan herself, and relieve Russia/China while threatening major Japanese territory (most likely some with IC’s on them). While there can be no “real true way” to use this strategy consistently, be aware of it. Also be aware it is very difficult to pull off successfully. Of course the minute you do this it is time to consider a KJF strat.
The best way you are going to pull it off is by an overconfident/ lazy Japanese player OR by putting decent pressure on Japan at multiple fronts distracting Japan from more basic goals it should be focused on.
CONCLUSION
Note all of these strategy’s are either fairly cheap (as in terms of actually investing IPC’s to the board) and/or flexible (ex: many of them can be aborted fairly quickly or diverted towards Germany.) They also work on the philosophy of Japan’s early supply problem while focusing on bailing out Russia. and stacking units in multiple theatres in as efficient of a way as possible to make Japan have to go “soft” in various theatres, hopefully providing you with better openings in Europe and Asia.
Also notice, in a way many of these strats will make the Axis respond to you. As many of these strategies are gearing the war to the centre of the board through Allied decision making. Example: if the UK is sending 4 armor per turn from N. Africa towards Persia, both Germany and Japan have to adjust to that.
I do not think you can ever count on beating Japan, or apply a consistent “one true strategy” to do so, only Japan can beat Japan. Hopefully you can limit her options, force some moves, increase the chances for her to make mistakes, employ flexible strats that can create opportuninities and openings, and slow her down enough in order to take care of Germany. If not, than the best way of dealing with Japan would be to go 100% Europe (so much as Japan isn’t threatening America anyway) and hopefully you can take down Germany before Japan swells to an unconquerable monster.
These strategies also assume NO’s and no tech. A game with tech would probably require a bit of a different approach
