Ethics in the use of artificial intelligence has generated a new and intense debate in Japan after the behavior of the mangaka Yoichiro Tanabe. Author faces strong criticism after using AI tool Grok to modify the image of a real-life idol without her permission. Tanabe shared an edited photograph of Riko Kudoa member of the group STU48, where the original image was altered to show her in a bikini, which caused an immediate reaction of rejection from the community and those affected.
The response of victims and the industry
The authority in this case comes from the direct statements of the artists involved and the official management of the group. Riko Kudo He publicly expressed his discomfort with the altered image. For her part, Mai Nakamura, a member of the group, demanded the removal of the post, pointing out that the “joke” was not funny at all.
Initially, the mangaka He attempted to justify the action by stating that the images were “reference material” for his idol-focused manga projects. Due to the seriousness of the matter, Tanabe deleted the publication, requested public apologies and was reportedly fired from his job.
Legal implications and professional ethics

This development highlights the legal and ethical risks that creators face when interacting with image generation tools.
“Misuse of AI to edit or distribute altered images of our members violates image and publicity rights, and could lead to legal consequences” — official statement of the STU48 administration.
A necessary limit for AI in art
The case of this mangaka serves as a stern warning to all professionals in the creative sector. Technology, although powerful, cannot override human consent or image rights. The swift action of STU48 management sets a necessary precedent to protect public figures from unwanted digital manipulation.
The dismissal of the author is an exemplary but necessary measure. A mangaka You must base your work on creativity and respect, and using AI to sexualize the image of a real person without their permission tarnishes the integrity of the profession. The excuse of using it as “reference material” does not justify the public distribution of content that violates the dignity of an artist. It is vital that the manga and anime industry establish clear ethical frameworks around the use of these tools to prevent innovation from becoming a tool of harassment.
Do you think the current laws in Japan are enough to stop the malicious use of AI against public figures, or is there a need for specific regulation for artists? We want to read your opinion in the comments!
