Ishida Mariko(石田真理子)

Ishida Mariko is a Japanese Adult Video (JAV) actress who debuted around the mid-2000s, based on available work listings, and appears to have maintained a career spanning well over a decade. Her initial roles leaned heavily into the mature woman genre, often featuring themes like milfs, housewives ("jinzuma/shufu"), and cosplay. Many early productions also involved group sex scenarios ("3P/4P"). A strong focus in Ishida's work has been on the mature lady ("jukujo") niche. Titles and genre tags indicate frequent appearances in productions centered around mature women, often including themes of infidelity and domesticity. Some of her earlier work also highlighted squirting and amateur ("shiroto") themes. Later in her career, Ishida seems to have branched out into more niche and specialized areas within JAV. The inclusion of a title from the "Bizarre Orgasm" series points to an exploration of BDSM themes, including bondage ("shibari/kinbaku"), enema ("kanchou"), and SM. Her work appears across several studios and makers, including Alice JAPAN, Nadeshiko, and Ruby. She has also appeared in a series, "Real Madame," suggesting a consistent presence in that particular brand of mature-themed content. In summary, Ishida Mariko is known for her work in the mature woman genre, with a later shift towards more specialized and niche content.
