Uchiyama Riko(内山理子)

Uchiyama Riko is a Japanese Adult Video (JAV) actress who debuted around 2010. Her career seems to have been active for at least a couple of years based on available information. Analyzing her listed works, Uchiyama's main genre focus appears to be on themes involving female dominance and exhibitionism, often featuring the "chijo" (slutty woman) archetype. Other common themes include group sex (3P/4P) scenarios and specific fetishes like miniskirt police officers and nurses. There is evidence of foot-related fetish content ("ashikoki") as well. Based on the limited data, it's difficult to definitively say if her genre preferences evolved significantly over time. The available titles suggest a consistent focus on the themes mentioned above throughout her active period. She seems to have been associated with NEXT GROUP as the primary studio for her productions. While not explicitly stated, the "○○セキュリティーサービス" series title suggests she appeared in a series of videos with this theme. Overall, Uchiyama Riko's style seems to center on sexually assertive female characters within fetish-driven scenarios, particularly those involving exhibitionism and group sex.
