Setouchi was born Harumi Mitani on 15 May 1922 in Tokushima, Tokushima Prefecture to Toyokichi and Koharu Mitani.[3] Toyokichi was a cabinetmaker who made Buddhist and Shinto religious objects.[2] In 1929, her family began using the surname Setouchi after her father was adopted by a family member.[3][2]
1950 she divorced her husband and serialized her first novel in a magazine.[3] She continued to have sexual relationships, including affairs with married men, and some of her novels were semi-autobiographical.[4][3]
In 1957, she won her first literary award for her novel "Qu Ailing, the Female College Student".[3][5] She then published Kashin ("Center of a Flower"),[5] which was criticized for the sexual content, and to which she responded, "The critics who say such things all must be impotent and their wives frigid."[3] Publishing her work was difficult for several years afterwards, and critics called her a "womb writer".[4][5]
She began to shift her novel writing focus to historical female writers and activists,[5] eventually including Kanoko Okamoto, Toshiko Tamura, Sugako Kanno, Fumiko Kaneko,[4] and Itō Noe.[6] In 1963, she was awarded The Women's Literature Prize (Joryu Bungaku Sho)[5] for her 1962 book Natsu no Owari ("The End of Summer"),[7] which became a best-seller.[4][3] In 1968, she published the essay Ai no Rinri ("The Ethics of Love").[4]
She received the Tanizaki Prize for her novel Hana ni Toe ("Ask the Flowers") in 1992,[9] and was named a Person of Cultural Merit in 1997.[5] Her translation of The Tale of Genji from Classical Japanese took six years to complete and was published in ten volumes in 1998.[12][10] She considered Prince Genji to be a plot device for the stories of the women of the court and used a contemporary version of Japanese for her translation.[12] The novel sold more than 2.1 million volumes by mid-1999.[12] After the book was published, she gave lectures and participated in discussion groups organized by her publisher for more than a year.[13][14]
