About Japan's colors: don't you think it would be better to choose something that doesn't try to relate to their current flag? White and red weren't really the colors of Japan at this point, and it would probably be better to use something more specific to the period and let this colors be used by someone else should they want to make a Japan were this would fit better. I particularly think that something with black or dark grey should be used.
