Americans often act and think as if the rest of the world don't exist, but the Japanese are far, far worse. Navel-gazing = size x ethnocentricity. What Japan lacks in size compared to the US, it more than makes up for in ethnocentricity.
I remember seeing an XKCD comic which featured a fact about "there only being [x amount] of [x type] lighthouses in the nation". "In the nation". So typical.
