On 14 July 2021, the Organizing Committee announced the creative team for the opening and closing ceremonies of the Olympics and Paralympics, and appointed Keigo Oyamada of Cornelius as a composer of the opening ceremony. It caused a growing number of people on social media to state that he was ineligible to be in such a role because he is widely known for his past bullying of people with apparent disabilities, such as Down syndrome. He has inflicted horrific abuse on his peers when at school; such as forcing them to eat their excrement, masturbate in front of other students, etc., and he himself often told about the disability abuse stories as vaunt in several interviews. On 16 July, a week before the opening ceremony, the Organizing Committee of the Olympic and Paralympic Games, which was questioned for insight and good sense, announced to support him as a composer and not to change the decision for the ceremonies. Toshirō Mutō, the chief executive of the Organizing Committee, said he wanted Oyamada to remain involved. Growing criticism forced Oyamada to announce his resignation on 19 July.
