At her peak, Oikawa was one of the most popular and well-known AV Idols in Japan. In 2003 (the earliest date available) she was #1 in the DMM list of the 100 top-ranked actresses by sales on their website. In 2004, even though she had retired in mid-year, she was still ranked #2, and even in 2005 she made the top 50 at #42.

More than half of her AV work are produced in 2002.

Oikawa's debut was not easy. AV producers did not think that she had special talent in their genre. She used her time for studying popular porn stars' acting (especially, she learned many things from Kurumi Morishita). Finally, Oikawa made her debut adult video at age nineteen for the Media Station Cosmos Plan label in September 2000. Then she released some videos from Alice Japan, Momotaro, etc., but she could not get big success. In her first year of adult work, she made only a few videos, including a softcore V-Cinema movie, Virgin Teacher Hinako in September 2001.
