Huh. I am guessing this is all very cost inefficient for the Japanese. I am imagine like in WWII and during the war in China when Japanese soldiers would need to find food for themselves. Having the whole map colored yellow does make it a bit different separate and categorize everything mentally. Also, didn’t the Japanese Navy also have occupation zones during WWII? Though as it was during WWII and in Indonesia, I am assuming any place the Navy took (I wonder if they had an equivalent of Marines, to be used for their own banana republics) was simply swallowed up as part of Japan proper. If Indonesia a part of Japan proper? I can see it happening with Australia if they clear out the Europeans and colonize the area, but Indonesia being metropole rather than colony brings in far too many people.Here is a little worlda I decided to make. There is not much lore to it; Imperial Japan's conquering spree in WW2 goes much further. Plenty of countries/regions do have an idea they are built around, though, if you want me to explain.
