on Ice, In This Corner of the World, Kakegurui, Banana Fish, Zombie Land Saga, Dororo (in co-production with Tezuka Productions), Dorohedoro, The God of High School, Jujutsu Kaisen, Attack on Titan (season 4), Vinland Saga (season 2), Chainsaw Man, Hell's Paradise: Jigokuraku, and the 2024 adaptation of Ranma ½. MAPPA is an acronym for Maruyama Animation Produce Project Association.

[5] Maruyama served as the company's first representative director, and the studio's initial goal was to produce Sunao Katabuchi's In This Corner of the World.

[10] Besides the animator's individual output within the studio, they also criticized the company's decision to produce four series concurrently.

[10] Kevin Cirugeda from Sakugablog suggested the problems were due to the studio's incredibly fast-paced growth and "recklessness".

[11] Cirugeda also noted that in the 20 televised animes MAPPA produced from the beginning of 2015 to the beginning of 2020, the company had only been on the production committee for four of them, all of which listed MAPPA near the bottom or at the very bottom of the list, indicating that they served to a capacity almost as if they were being specifically contracted for work even on "original" series.
