Hamasaki Rio, a Japanese , was born on June 11, 1988. She is a freelance AV actress from Tokyo, Japan. She became an AV actress in October 2006. In 2007, her popularity suddenly skyrocketed. As a solo AV actress (meaning she did not work exclusively for a single company), the quantity and speed of her video releases were exceptionally high, to a degree described as astonishing. In terms of sheer output volume alone, she had surpassed the entire AV industry and was acclaimed as the reigning champion of solo AV actress releases.
