In 1984, she debuted with "Coelacanth Burein," a mystery novel published by Futabasha. Writing about people's mentality from an original perspective, she has produced a lot of shocking stories.
She was born August 7, 1959 in Nagasaki, Nagasaki Prefecture, Japan. Her father left the family when she and her younger sister were in primary school. Her mother was a dance teacher and bar hostess, who soon began living with another dance instructor, and later remarried. Shungiku was often forced to sleep with her stepfather, and her mother would allow it. One of Shungiku's happiest memories from her childhood was getting a ream of rough paper from her fourth grade teacher, as a gift for saying that her dream was to become a manga artist.
Shungiku dropped out of high school in her second year and worked in restaurants, bars, in a printshop, and as a domestic. Sometimes she slept under bridges. Five years later she left Nagasaki for Tokyo with her beloved manga and $7,000 in savings. She graduated from Nagasaki Prefectural Nagasaki Minami High School. She then attended Keio University, majoring in philosophy in the Department of Literature, but left before completing a degree. Uchida is currently represented by the talent management firm Knockout.
Her representative works include Wakaokusama Tamajigoku and Minami-kun no Koibito (which was later adapted into three drama series). Uchida is also known as "Denko-chan", the mascot character for The Tokyo Electric Power Company.
Besides a career as a manga artist, she is also active with music and as a novelist. She wrote a controversial semi-autobiographical book called "Fatherfucker" which was also made into a live-action movie.
