アリスJAPAN
After a number of years away from the entertainment industry, Ozawa created a stir when she made her debut as an AV performer in April 2004 with the video "Decision" () for the Alice Japan studio, the AV subsidiary of Japan Home Video. Ozawa made several more featured actress AVs with Alice Japan over the next two years. In 2007 and in 2009, Alice Japan released two videos on their Alice Pink label which collected scenes from Ozawa's previous videos remastered in the new thinner mosaic used to censor the genitals in all Japanese AVs.
