Japanese anime posters

Since Japan is the best country to produce anime/manga, there are a lot of different productions. Therefore when they promote or introduce their anime/manga, they also need a lot of graphics works such as posters in order to promote their anime/manga.

I looked at some of the posters and I think it is quite different from the western animation posters, the Japanese animation posters are more focusing on character illustrations, while the western style is more focusing on the actual design and more "3D" effect.

It is good to know what is the difference between both styles of posters so that if I have a chance to design a Japanese animation poster, I can know about it.
