Rieko Matsuura (松浦 理恵子) was born on August 7, 1958 in Matsuyama, Ehime Prefecture, Japan.
She studied at Aoyama Gakuin University of Liberal Arts and is a postmodern novelist.
She went from Marugame West Middle School to Kagawa Prefecture Otemae Middle School, a private school in the area. Matsuura attended Aoyama Gakuin University where she majored in French literature. In her teens, she had read Marquis de Sade and Jean Genet, and she wished to be in the French literature department so she could read their works in the original language. In 1978, while enrolled at school, she won the Bungakuki New Writers Award (文學界新人賞?) award for writing "The Day of the Funeral", her first book. In 1987, her book Natural Woman was given a rave review by Kenji Nakagami, bringing attention to her. In 1994, her book Apprenticeship of Big Toe P, about the travels of a woman whose big toe on her right foot turns into a penis, won the Women Writers' Prize. The book also went on to be a bestseller. Also in 1994, she co-wrote a film adaptation of Natural Woman, which was released in 1994.
Seven years passed between Apprenticeship of Big Toe P and Opposite Version, and another seven until Kenshin was published. The latter book, published in 2007, won the Yomiuri Prize in 2008. She is currently a committee member for the Shinchō New Writers Award.
