In 2005, Karemara starred as Jeanne in Raoul Peck's film Sometimes in April, about the Rwandan genocide.[4] The same year, she decided to settle in Kigali.[2] Upon moving to the country, Karemara became involved in cultural projects, including staging interactive plays in bars and in the streets of Rwandan cities, in order to create a common history. Along with Cécilia Kankonda, she set up a "sound cathedral" built from recordings of memories in which participants could tell their memories of Rwanda before 1994.[5] In 2006, Karemara and seven other women established the Ishyo Arts Center in Kigali to support culture in the capital, which did not have a theatre until that point.[1]
