Although reaching the Szechwan region doesn't look like it's in the cards, it looks like the Japanese' passive early-game strategy will at least net them one, if not two, of what I would consider the three main reasonable objectives in China, namely control of the Changsha-Nanning railway and resources and an unobstructed north-south rail link.
Only the third, control of Sian, appears to be out of reach.
These two objective are indeed close to being fulfilled.
However, going to Sian is something I find too expensive.
Yet, once finished with the Nationalist Chinese, it is quite possible that the Japanese will find some time to tackle the communists.
Note that the successes also held in large part to rather good rolls. Even the bad rolls, such as the failure to take Changsha, have been nice: overall, the Japanese have not lost many units. I did not count exactly, but it is three or four cheap units I believe.
If they have the same kind of luck in the next summer, they may well capture Sian. As always, I won't attack recklessly. The status-quo is quite satisfiying for the Japanese. Especially now that they are close to controlling two more resources. Better 5 resources and no losses than 6 resources that cost many units in fights. In any case, the Chinese can now be tamed with but some strategic bombardment raids. It's likely that careful attacks will attrition the Communist Chinese army enough that at some point it will just crumble like the nationalist army did.
