Katayama Ritsuko(片山立子)

Katayama Ritsuko is a Japanese Adult Video (JAV) actress known for her work primarily in the mature women (熟女) and married woman (人妻) genres. Her career appears to have begun around 2007, based on available information, and lasted at least until 2010. Her early work, as suggested by titles and genre tags, focused heavily on themes of infidelity (不倫), group sex (乱交), and the "naughty wife" or "slutty wife" (痴女) archetype, often involving 3P or 4P scenarios. She appeared in numerous productions centered around these themes, suggesting a clear preference or market demand for her performance within this niche. Later titles indicate a continued focus on the mature married woman genre, with some emphasis on illicit affairs and amateur-style filming (ハメ撮り). This suggests a possible slight evolution towards a more realistic or voyeuristic portrayal of the married woman fantasy, rather than solely focusing on extreme sexual scenarios. Katayama Ritsuko primarily worked with the studio Raidix, appearing in several of their productions. She also featured in the "人妻専科 お姉さんがしてあげるEX" (Hitodzuma Senka Oneesan ga Shite Ageru EX) series. Her style seems to be characterized by a mature, sophisticated, and possibly alluring portrayal of the married woman, fitting the common tropes of the genre.
