4. Bakemonogatari (2009): 78,671 units average. Bakemonogatari is the best-selling full-length anime of the 21st century.
And
still they won't release the original light novels stateside.
Damn, really? It was a good series, but I would have never guessed.
OT: This works both ways sort of. Cowboy Bebop is one of the most critically acclaimed series ever released in the west but most Japanese anime fans don't give two shits about it.
Also, you can't forget Lupin III. He's like Japan's Mickey Mouse and western anime/manga fans know very little about him outside of that one Miyazaki movie.
