Japan in China: 1937 - 1945

[Fuchs]

Maybe there are Japanese- or Chinese-speaking (whatever dialect) people here who can point us at (comprehensible, that is = English) documents about the episode?

The Japanese would probably omit some not so comfortable info, but those omissions aren't about tactics to be adopted anyway.

How about some exchange officer students at military colleges, bored military attachés?
