Kumi has rarely appeared in full length fetish films that have been released, though she has been included in a handful of segmented/compilation releases such as Simon Benson's "Petgirls Divas Compilation 2"; rope shibari films including "A Date with Danger" where Kumi was featured in a seperate segment against Anastasia Pierce, the similar "Lipstick & Latex" (from Bon Vue). Her feature starring films have included "Vacbed - A Latex Fantasy" a re-creation of her X-mas photo-shoot set for vacbed.com; "When Kumi Met Julie (Simone)" (from Harmony Concepts) and a small though featured role as the new rubber convert in Robert Zak's "Rubberella 3: The Facility" where she was head shaved on screen. She also has a role in Part 4 of Fetish Academy (Marquis Films).

She also has two European Fetish Award nominations - Special Achievement: 2008 ("for her long-time achievement"), 2010 ("for her ongoing work all around the world"). In 2011 she won for "her retirement from modelling, for enriching our scene in so many different ways".
Kumi publicly announced in August 2010 on her blog that her "days of working as a fetish model are [over]". She listed no public reason for her retirment. It was also not stated if she would be removing her public webpages as she is now retired.
