Kosugi Chiko(小杉チコ)

Kosugi Chiko is a Japanese Adult Video (JAV) actress who debuted around late 2007, and whose career appears to have spanned several years, with releases still appearing as late as 2015. Based on her available works, Kosugi Chiko seems to have been primarily associated with the "big breasts" (kyonyuu) genre, often within a school setting. Many of her titles and genre tags indicate a focus on school themes, including "schoolgirls" (joshikousei), "school uniforms" (gakuseifuku), and even "female teachers" (jokyoushi), suggesting a strong leaning towards the "schoolgirl" subgenre popular in JAV. While the available information is limited, there may be a slight shift in her work over time, as the later title suggests a potential move into more explicit "investigation" or "search" themes alongside the existing schoolgirl and big breast focus. She appears to have primarily worked with the studio h.m.p. There is no clear indication of her being linked to a specific series, although some of her works are part of the "AV History Library" series. Overall, Kosugi Chiko is remembered for her work centered around the big breasts schoolgirl theme, a popular niche within the JAV industry.
