Whats up with all the censored Hentai?
Due to idealistic reasons beyond all sense and reason, depictions of genetilia are illegal in Japan, meaning that Japanese-live-action porn and hentai alike have to feature some sort of censorship which occludes the genitilia. In movies this takes the form of mosiacs, while in doujins this usually takes the form of strategically-placed white bars. Since the vast majority of hentai is produced in Japan, the vast majority of hentai is censored. However, when a hentai movie or manga is licensed for distribution in the United States, it is the original, uncensored version which is distributed. Thus, fortunately, the hundreds of licensed movies which can be downloaded from Hentai-Key are uncensored.
