The controversy surrounding the upcoming Mii-chan and Yamada-san anime adaptation has taken another turn after Tomoko Katsuyama, founder and secretary-general of Japan’s Developmental Disabilities Association, publicly clarified the organization’s role and revealed that she negotiated for expert supervision and staff training to be included in the anime.
Her comments come after a response attributed to the association circulated widely online, prompting criticism and confusion over whether the organization supported or was directly involved with the anime adaptation.
Association Denies Supervising the Anime
Addressing the growing discussion on X, Katsuyama stressed that the association itself is not serving as a supervisor for the anime.
“Our organization is not taking on supervision. Please don’t misunderstand.”
She explained that while the association is not directly supervising the project, she had been in discussions with Kodansha to ensure the anime would receive appropriate expert oversight.
“I negotiated to have expert supervision added to the anime and even staff training for the sake of people with developmental disabilities. Please forgive me.”
According to Katsuyama, the goal of those discussions was to help ensure the adaptation would portray developmental disabilities responsibly rather than to place the association in a production role.
She also clarified that while people associated with the organization have previously worked as supervisors on projects involving developmental disabilities, the association itself is not serving as a supervisor for the Mii-chan and Yamada-san anime adaptation.
Katsuyama Apologizes for Not Reading the Entire Manga Earlier
Another point of criticism centered on Katsuyama’s admission that she had not personally read the complete manga when the controversy first erupted.
In a subsequent post, she apologized and revealed that she had since purchased every volume.
“I bought all the volumes. I’m going to read them all. I’m truly sorry.”
Responding to criticism online, Katsuyama explained that the earlier response shared online had been written by staff members who had already finished reading the series.
“The reply was written by staff who had read all the volumes. Our office only had up to Volume 4, so I bought the rest and read them.”
She also clarified that the widely circulated response was not an official statement issued by the association, but rather a reply sent to an individual inquiry that was later reposted on anonymous forums and spread across social media.
Criticism Continues Despite the Clarification
Despite Katsuyama’s explanation, criticism has continued across Japanese social media, with many users arguing that her clarification did not address the concerns surrounding the association’s earlier response.
Some users questioned why the association had responded to inquiries about the manga before Katsuyama had personally finished reading the series, while others criticized what they viewed as an overly defensive explanation.
“It just sounds irresponsible and focused on self-defense. You hadn’t even read it before saying it wasn’t discriminatory. Whatever position you take, you should have read it first.”
Others also sought clarification over whether Japan’s Developmental Disabilities Association would be supervising the anime adaptation, prompting Katsuyama to reiterate that the organization is not taking on that role.
The continued criticism highlights that the debate surrounding Mii-chan and Yamada-san remains far from settled, with opinions in Japan still divided over both the manga’s portrayal of developmental disabilities and the association’s response to the controversy.
Harassment Escalated as the Controversy Spread
Katsuyama also described the personal toll the controversy has taken.
She said she spent an entire day responding to questions regarding the manga before the situation escalated further.
“I ended up spending the whole day dealing with the Mii-chan and Yamada-san manga issue.”
According to Katsuyama, she later received an arson threat, leading to police involvement.
“I even received an arson threat, so the police became involved.”
She also appealed for understanding, saying she hoped the controversy would not create further division between people with developmental disabilities and the wider public.
“I hope this doesn’t create a divide between people with developmental disabilities and everyone else.”
Clarification Adds New Context to the Ongoing Debate
Katsuyama’s latest statements provide additional context to one of the biggest controversies surrounding the Mii-chan and Yamada-san anime adaptation.
While she reiterated that Japan’s Developmental Disabilities Association is not supervising the anime, she revealed that discussions with Kodansha focused on introducing expert supervision and staff training during production. She also clarified that the viral response circulating online was not an official organizational statement, while addressing criticism over her own involvement and condemning the harassment directed at her following the backlash.
With debate surrounding the adaptation continuing in Japan, her comments offer the clearest explanation yet of the association’s position and the steps she says were taken behind the scenes. Bookmark Otaku Mantra for more anime news and updates!
