Question Japan- China Silk Map

[Jags1]

I have a silk map that appears to be a Japanese "war" map of a city in China showing streets but this is a guess on my part. Pre-WW2 as it has "bi-planes"?
Really appreciate any help on this.

The pictures are rotated 90 degrees to the right.
It's not a map of a city, but a map of China. The black-white lines symbolize "railroad", and kanji shows location names (city, mountain, river or bay).

Wow... Do you have any idea what the meaning is of the Kanji in picture #1426 or the two symbols at the top of #1425? Do you think this was part of the "invasion" plan by Japan?
Really appreciate the help! Very interesting to say the least

It's just a souvenir or something. (Seems like a furoshiki to me.)
