Sakagami Yuko(坂上優子)

Sakagami Yuko is a Japanese Adult Video (JAV) actress known for her work primarily featuring mature women. Based on available information, her career appears to have begun around 2013. Her early work, as suggested by the title "初撮り五十路妻ドキュメント 坂上優子," and associated tags, leaned heavily into the "mature woman" (熟女) and "housewife/married woman" (人妻・主婦) genres, often presented in a documentary style. The tag "50s" (五十路) confirms that she was playing characters in that age range. The presence of "巨乳" (big breasts) as a tag also indicates a physical characteristic that was often highlighted in her performances. She appears to have frequently worked in solo pieces (単体作品). While it is difficult to definitively state a genre evolution without a comprehensive list of her filmography, the initial focus on documentary-style mature woman content suggests a potential specialization in that niche. The available title points to Center Village as one of the studios she has worked with. Given the reference to a series called "初撮り五十路妻ドキュメント," it's likely she appeared in multiple installments of that series. Overall, Sakagami Yuko is characterized by her portrayal of mature, often married, women, with an emphasis on naturalistic performances and a focus on her physical attributes.
