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 January 2007 from using the name after a woman named Mary Katsumi sued over the resemblance to her own name. In October 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 Angouleme, France

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. She was required to give up her stage name, "Katsumi," after a legal decision in January 2007 by a French judge in Creteil, France. In September of 2007, the actress was fined 20,000 euros for having broken the legal agreement not to use the name "Katsumi."
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.
