There are things that you don’t come across very often, even when rummaging through the bottom of the doujinshi barrel. Chief among those things are doujin of Western cartoons. While there are some very minor exceptions and a very small fan base, most Western cartoons are almost entirely unknown to the Japanese. The few that are have been the ones which got anime re-imaginings like TMNT and Powerpuff Girls, but even those weren’t exactly smash hits and PPG in particular bears little resemblance to its original form.
The Simpsons, while popular in nearly every other country on the planet, have also failed to break into the Japanese market as a cartoon. Fox has tried a few times, but for some reason they’ve just never been able to get any traction. Still, interestingly enough, The Simpsons are likely one of the most recognizable western cartoons to Japanese audiences. The reason is that The Simpsons were used for advertisements for C.C. Lemon and, later, in a cross promotion with Mister Donut (commonly shortened to Misudo in Japan). Mister Donut actually has a fairly interesting history, but that’s maybe a story for another doujin.
