Yamada Sachiko(山田幸子)

Yamada Sachiko is a Japanese Adult Video (JAV) actress who appears to have debuted around the mid-2000s, judging from available information. Her career, based on limited publicly accessible data, seems to have been active for at least a few years. Her filmography, though details may be incomplete, indicates a focus on specific genres early in her career. The available title and tags suggest a strong presence in the "blowing" (squirting) niche, often featuring schoolgirl themes, uniforms, and large breasts (busty). The "Shiokuki Joshi Kosei 10 Renpatsu" series (which translates to "Squirting High School Girl 10 Consecutive Shots") serves as a prime example of this, with Yamada appearing in at least one installment. Due to the limited information available, it's difficult to ascertain any significant genre evolution over time. However, her early work seems heavily concentrated on the aforementioned niche. Crystal Eizo appears to be one of the studios she worked with. In summary, Yamada Sachiko's on-screen persona seems to have been built around a combination of youthful imagery, busty physique, and the popular "blowing" fetish, primarily within the context of schoolgirl themed JAV productions.
