Yanagi Sachiko(柳木幸子)

Yanagi Sachiko is a JAV actress who debuted around 2008. While a complete filmography is unavailable, her career appears to have spanned at least a few years based on available information. From the limited information available, her work seems to lean heavily into the mature woman (熟女) and housewife (人妻・主婦) genres. Many of her films also feature elements such as fellatio (フェラ), group sex (3P・4P), and finger stimulation (指マン). The emphasis on mature themes and specific sexual acts suggests a focus on satisfying a particular niche within the JAV market. Given the limited scope of publicly available data, it's difficult to definitively determine if her genre focus evolved significantly over time. However, her appearance in the "人妻の友DX" series suggests a possible recurring relationship with Royal Art studio during at least a portion of her career. In summary, Yanagi Sachiko seems to have primarily performed in JAVs catering to audiences interested in mature women and housewives, with a strong emphasis on specific sexual acts within those genres.
