In Japan, pornography has unique characteristics that readily distinguish it from western pornography. Pornographic films are known as "adult videos" (AV) in Japan, so Japanese adult videos (JAV) refers to the Japanese Adult Video industry. Animated films are referred to as hentai in English, but in Japan the terms "adult anime" and "erotic animation" (or ero anime) are used. In addition to pornographic videos and magazines featuring live actors, there are now categories of pornographic manga and anime (i.e., hentai), and pornographic computer games (eroge; for both PC and game consoles).
Reflecting Japan's views on sexuality and culture, Japanese pornography delves into a wide spectrum of heterosexual, homosexual, and transgender sexual acts in addition to unique fetishes and paraphilias. Starting with erotic stories and wood block prints from before the 20th century, Japanese pornography evolved into distinct subcategories. Partly under attempts to circumvent Japanese laws regarding censorship, but also to cater to particular fetishes, actors and producers often feature subject matter that in western pornography had historically been unseen or rarely depicted, and even now is less frequently featured; bukkake (group ejaculation), gokkun (consuming semen), omorashi (needing to urinate), and tentacle erotica are a few uniquely Japanese genres of erotica. Lolicon (young girls), shotacon (young boys), and their contribution to the controversy regarding the regulation of cartoon pornography depicting minors has been a major issue concerning child protection, free speech, and public morality both inside and outside Japan.
