Established on February 4, 2013, by director Masaaki Yuasa and producer Eunyoung Choi, the studio has produced feature films and animated series, as well as co-productions, compilation films, and episodes of series for other studios. Science Saru's first animation was the "Food Chain" episode of the American animated series Adventure Time (2014); its most recent projects are the animated feature film Inu-Oh (2021), two short films for the animated anthology project Star Wars: Visions (2021), and the animated series The Heike Story (2021), Yurei Deco (2022), Scott Pilgrim Takes Off (2023), and Dandadan (2024).

The studio was led by Eunyoung Choi until 2025.
