I've updated the two maps by adding a third one based on the recommendation by propbeanie of using the mission editor to get a screencapture.
You now have options of the original ones I did plus a COLOR one using the info straight from your SH4 install!
The color one has major cities and Japanese ports including Sasebo, Kure, and Yokosuka. The exception is Yokohama, which was basically Tokyo.
Enjoy!
