You may be aware, from hanging around the internet, that Japan loves the Nintendo DS. But it takes a nice little mix of pictures and statistics to really ram the point home.

This chart was released by Nintendo today, and shows the percentage of a market's population that owns a DS. By extension, it also explains succinctly just how bonkers the Japanese population has been for the handheld. I mean, over 20% of the population owning a DS? Crazy. That's one in five Japanese people. Not one in five Japanese gamers. One in five Japanese people.
