I am going strictly by the colors in the flags. Canada=Starks (white and red, cold) USA/UK/France=Hardying or Tully? (red, white and blue) China=Lannisters (red and yellow)--Tyrion would love this because the Chinese revere dragons. Greece=Arryns (blue and white) Japan has a sun on its flag, but no spear, so cannot be Dorne. But it could be the Iron Islands--the Japanese attitude to non-Japanese is very similar to that of the Ironborn. And they also have a take-no-prisoners attitude when fighting. Tyrells could be the English--English rose, etc.
