This scenario just seemed a bit boring. Not much more to be said.
The Japanese were more powerful at times.
Having seen many of your scenarios before now, this just can't be a five for creativity.

Isn't this one of the Quick Battle maps that you used for the map? Also, how about actually naming the cities instead of calling them "Captured Village" or "Capital."
There weren't any to speak of.

I think you need to put more time into your scenarios. Take time to look up the names of cities and create good maps. Write a script so that you can give an introduction and customize your nations. Your ideas and intentions are good, but just put more care into your work.
