Life and career Nao Oikawa was born in Hiroshima. Her family moved to Tokyo when she was a little girl. At age 18, when she graduated from high school and began design school, she met a scout who proposed she become an AV idol. "That time, my hair was bleached and curly. My agency told me to get my hair back to straight black. One day in the office, one staff picked Oikawa as family name from a book, another staff picked Nao from another book. This is where my stage name came from."Bukkake Ittassyo 2003-12Shizentai Nimo Hodo Ga Aru 2009-08

AV career Debut 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.
