Sakaguchi Rumiko(坂口瑠美子)

Sakaguchi Rumiko is a JAV actress who appears to have debuted around the late 2000s. Her career seems to have been active for at least several years, based on the availability of her works. Analyzing her available work information suggests a focus on mature women (熟女), specifically married women or housewives (人妻・主婦), often within the "older woman" (大年増) niche. The tags indicate a tendency towards content involving group sex (3P・4P) and oral sex (クンニ), often featuring slender body types. It is difficult to determine any specific genre evolution over time with the limited information available. However, the consistent presence of mature woman themes suggests a specialization within that area. She appears in the "大年増（おおどしま）" series. While specific studio information is sparse, at least one of her works was released by Gen'eisha (現映社). Based on the available information, Sakaguchi Rumiko cultivated a persona centered on the appeal of mature, slender women participating in various sexual scenarios.
