14. Crayon Shin-Chan with 870+ Episodes
Only 78 episodes of this crude family sitcom were dubbed by FUNimation. Language barriers seem to have been difficult to overcome, especially since a reoccurring scene in this anime seems to be a closeup shot of a mischievous, young boy’s bosom. How did such a goofy masterpiece make it on this list of the longest running anime in Japan? The same way that The Simpsons and South Park have overseas – with tons and tons of laughter! Don’t underestimate the power of a good dirty joke.
