Ishikawa Ryoko(石川遼子)

Ishikawa Ryoko is a Japanese Adult Video (JAV) actress whose career appears to have begun around 2008 and continued for several years, based on the available work list. While a comprehensive filmography isn't provided, the titles suggest a focus on mature women ("juku-jo", "hitodzuma") and related themes. Her work frequently centers around the "mature woman" genre, often depicting married women or housewives in scenarios involving infidelity ("furin") or encounters with strangers ("nanpa"). Many of her roles also seem to incorporate elements of the adult entertainment industry, like hostess clubs ("kyabajo") or soaplands. The presence of tags like "kyonyu" (large breasts) indicates a focus on physical attributes as well. Common acts featured include ejaculation inside ("nakadashi"), fellatio ("fella"), and cunnilingus ("kunni"). The actress appears in several series from the studio Graiz, such as "Bijin Tsuma Fera 4-jikan Collection" (Beautiful Wife Fellatio 4-Hour Collection), "Hitodzuma Senmon 4-jikan" (Housewife Special 4-Hour), and "Koukyuu Fuzoku Hime Gensen 4-jikan" (Carefully Selected Luxury Soapland Princess 4-Hour). She also appeared in a series by Graffiti Japan. The titles and series names suggest that Ishikawa Ryoko was often cast in longer-form productions and compilation videos. Her style seems to be rooted in portraying a specific archetype of older, attractive women in various adult situations.
