An AV idol or AV actress is a type of pornographic film actress in Japan. It is a sub-category of the idol culture in Japanese pop entertainment. AV idols work in the pornographic business, often both as an actress as well as a model as the video performances vary widely, from suggestive softcore imagery to hardcore pornography. The industry is noted for having frequent turnovers; since the dawn of the AV industry in the early 1980s, hundreds of AV idols have debuted every year, with an average career span of about a year, appearing in five or ten videos during that time. Some successful AV idols move into daytime television or other fields after their careers have waned, while the reverse can happen as well where actresses move into pornographic videos if their normal work has dried up.
