Mamiya Koko(間宮ココ)

Mamiya Koko is a JAV actress who appears to have debuted around 2012, based on the available work list, and maintained a presence in the industry for several years. Her filmography suggests a strong focus on the mature woman (人妻・主婦) genre, often involving themes of infidelity (不倫) and explicit acts like unprotected sex (中出し). She also has a number of works focusing on handjobs (手コキ) and nurse (看護婦・ナース) themes. Early in her career, she appeared in series such as "Te Koki Clinic" and "Doro Nure Oneesan," indicating a willingness to explore niche fetish themes. The presence of terms like "bondage" (拘束), "humiliation" (辱め), and "electric massager" (電マ) in some titles also suggests an interest in BDSM-lite and exhibitionist content. Later works and best-of compilations indicate a consistent focus on the married woman genre, with a particular emphasis on uncensored (生強●) and deep insemination (中出し) content. Mamiya Koko has worked with a variety of studios, including SOD Create and Baby Entertainment early in her career. However, a significant portion of her filmography appears to be associated with Big Morkal, particularly for her mature woman and compilation works. Series like "Danchi Tsuma" and "Okusan no Ie de Ochanoma Sex Shimasen ka?" further solidify her image within this genre. Overall, Mamiya Koko cultivated a career primarily centered around the mature woman niche within the JAV industry, with a willingness to explore a range of sexual acts and themes. While she has taken on other roles, her work with Big Morkal in particular seems to have solidified her image as a performer specializing in the married woman genre.
