Rin Aoki

Her first AV production with S1, K-cup Active Idol Risky Mosaic, appeared in May 2006 and was directed by Hideto Aki who also directed most of her subsequent videos with S1. She says she was comfortable with her first AV work but was embarrassed about showing her nipples because they were small and pale colored. After making ten original videos with S1 in almost a year, she left the studio along with Maria Ozawa and other fellow S1 actresses to join the startup company DAS. In contrast to S1 which specializes in the "softer" type of pornography with mostly straightforward boy-girl sex scenes, DAS videos ventured into more extreme areas such as simulated rape, creampie and watersports. Aoki starred in the first video of the DAS series DASD-001, 20 Shots Creampie!, released on April 25, 2007. She has made several more movies for DAS including her first inter-racial role in the DAS "Black Gang Rape" series.

By August 2008, Aoki was with a new start-up studio, OPPAI, which publicized her first video for them, 108 cm Kcup Rin, with a signing and modeling event. Although continuing to make movies for OPPAI, she has also appeared in videos for Attackers and yet another new studio, Ranmaru.

In the 2010s, Aoki became a prolific freelance actress appearing and performing with many different studios from Venus and Wanz Factory to Madonna. As of 2020 she remains as an active performer and appeared in more than 500 adult films.

Aoki is one of the latest examples of the very popular genre of "Big-Bust" models in the Japanese AV industry going back to Kimiko Matsuzaka. As a measure of her popularity in Japan, the listing of the top 100 actresses by sales from the DMM website shows Aoki ranked #3 in 2006 and #9 in 2007.

Aoki had a small preview appearance in the S1 compilation video Hyper – Barely There Mosaic (ハイパーギリギリモザイク) with AV idols Sora Aoi, Yua Aida, Yuma Asami, Maria Ozawa and Honoka which won the 2006 AV Open competition among Japanese porn studios.

At the 7th annual Takeshi Kitano Entertainment Awards for 2006 sponsored by the Japanese tabloid newspaper Tokyo Sports (東京スポーツ), Aoki was honored with the Star AV Actress Award (主演AV女優賞).
