Itou Youko(伊藤洋子)

Itou Youko is a Japanese Adult Video (JAV) actress whose career began around the early 2000s and appears to have continued, at least intermittently, into the late 2010s. Based on available information, she primarily stars in mature woman ("熟女") themed JAVs. Her work often features genres such as MILF ("義母", "人妻"), and she has been involved in productions featuring onanism, vibrator use, fellatio, and incest themes. Some of her work also includes group sex scenarios like 3P and 4P. While her earlier work, exemplified by series like "THE・義母図鑑," focused intensely on specific mature woman themes, later appearances, such as in "月刊熟女秘宝館," suggest a move towards compilation or "best of" releases within the mature woman genre, indicating a possible shift towards re-packaging of older content. The studio "MARX" appears in her earlier work, while "NEXT GROUP" produced some of her later appearances. She is known to have appeared in at least two series, "THE・義母図鑑" and "月刊熟女秘宝館". In summary, Itou Youko established herself as a JAV actress specializing in the mature woman niche, focusing on a range of related themes and genres throughout her career.
