i wonder why the 2 Korea are white, that and paraguay/bolivia...
Let's see: Irak, Afghanistan, the 2 Korea, Former Yougoslavia, Somalia, Congo (ex-Zaire), Is there a relationship with war?
And the green???...it's the opposite of orange in this case, Japan is separated, either it's comparison to Japan, or it's a link toward Japan (like quantity of mangas sold outside japan...)
Edit: Number of Japanese restaurant?
