Izumi Koharu(泉小春)

Izumi Koharu is a JAV actress who debuted around 2008. While information on her complete filmography is limited, she appears to have been active for at least a short period during that time. Based on available information, specifically the title "糞尿家族 ロビンソン3," Izumi Koharu's work seems to have heavily leaned towards niche and extreme genres, particularly scat (specifically mentioned as "スカトロ, 脱糞" in Japanese). The presence of "巨乳" (big breasts) in the tags also suggests an emphasis on busty actresses, a common characteristic within certain segments of the JAV industry. It's difficult to determine any genre evolution or shifts in studio affiliations with the limited data. However, the single identified work was released by V&R Planning and is part of the "糞尿家族" (Feces Family) series, suggesting she may have primarily worked with that studio within the confines of that specific series or related productions. In summary, Izumi Koharu's profile indicates a career focused on a very specific and arguably controversial niche within the JAV landscape. Her limited number of known releases makes it challenging to paint a complete picture of her style beyond the clear focus on scatological themes and large breasts.
