Since the majority of all hentai materials are produced in Japan, it was, at one time, very difficult for someone living out of that country to be able to get hold of their favorite Japanese hentai manga (comic) or anime (cartoon). In the past the only way to obtain hentai materials was through specialty bookstores that only had a limited selection and a very limited supply. With the growth of the internet combined with the availability of home computers, this is no longer true.
