After studying political science for a year at Grenoble Institute of Political Studies, she entered the adult film industry in 2002 at about the age of 23, and has since appeared in over 370 films. In December 2006, Katsuni signed an exclusive performing contract with Digital Playground. She originally performed using the stage name Katsumi (a common given name in Japan for both sexes), but she was barred by a French judge in Créteil, France in January 2007 from using the name, after a woman named Mary Katsumi sued over the resemblance to her own name. In September 2007, Katsuni was fined €20,000 for violations of the ban on using the name "Katsumi". In 2011 she promoted Hentai during a comic convention in Angoulême, France
In May of 2006, she got breast implants, going from a size of 32B to a 34D. Her first film with her new breasts, French ConneXion of Marc Dorcel Productions, came out at the beginning of 2007. In the meantime, Katsuni also graced the cover of Marquis magazine, a leader in fetishism, and hosted the weekly program, En attendant minuit, broadcast by TPS Star, a TV show in France. At the beginning of 2007, she signed an exclusive contract with Digital Playground.
Between 2002 and 2008, Katsuni was the winner of 29 international awards in the world of porn.
In July 2008 Katsuni released "My Fucking Life" (Marc Dorcel Studios). The movie is partly a documentary on Katsuni's daily life over a year, with a look at her shoots in Las Vegas, on set during filming in Porn Valley, along with a bit of her personal life.
In 2009, Katsuni was the official ambassador for the French porn awards, Hot d'Or, in 2009. She herself received two Hot d'Or awards in 2009.
Complex magazine ranked Katsuni at #3 on their list of "The Top 50 Hottest Asian Porn Stars of All Time", #14 on their list of "The Top 100 Hottest Porn Stars (Right Now)", and #48 on their list of "The 50 Prettiest Porn Stars of All Time".
