To me, it is very difficult for the Japanese really to accomplish anything in any meaningful amount of time without running some big risks.
At any rate, here is my set up. Not having a usual Chinese setup to work with, this is fairly close to what I think is ok.
Pretty much all the optional rules are in play that matter here and that includes unlimited breakdown and Nationalist attack weakness (attack at half strength).
The Japanese setup includes the ability to pull in all units from Japan over the first turn. (I typically start with a naval, put the transports out and suck all the troops out of Japan and land them the following turn in China).
I had been sending Yamamoto and the bulk of the troops coming over from Japan down south, but I have not really been getting anywhere doing that between bad weather and the Chinese slowing my advance by a very slow with-drawl. This set up sort of leaves Canton on its own while I plan on using more troops up north to try to accomplish something.
To me, the Communist section is the real danger as they will get most of the re-enforcements.
At any rate, the idea with this setup is to break down 3-4 corps (this one has 3) and use the divisions where the Nationalists can't get a good shot on them to help form up a more solid line and also provide some forces to actually do something with.
In my set up, I also pull the HQ out of Manchuria along with the motorized infantry. (You can see the motorized infantry on the border). The HQ is railed in on the second Japanese impulse when they take a land and is used to put the units along the northern part of the front into supply.
This is sort of a primer for a discussion on this topic (setups for the Japanese and Chinese using the new map).
