Sumire Uesaka Withdraws from Kyoto International Manga & Anime Fair After Death Threats
On September 14, 2026, Uesaka’s agency, Voice Kit, announced that the voice actor had received threatening emails stating intentions to "kidnap and kill" her. Consequently, the organizing committee of the Kyoto International Manga & Anime Fair (KyoMaf) confirmed on September 16 that Uesaka would withdraw from her scheduled appearances at the event held on September 19–20 in Kyoto. The agency stated they are reviewing her participation in other events and have reported the matter to the police, highlighting the growing security concerns for high-profile talent.
Kenichiro Ito Enters Medical Leave Due to Brain Hemorrhage
Veteran voice actor Kenichiro Ito, known for roles such as Yuzo Shiraishi in Golden Kamuy and Jin Tamura in Yowamushi Pedal, has entered a period of rest due to a brain hemorrhage. His agency, Mouse Promotion, announced on September 11 that the 52-year-old was transported from his home to a hospital where he underwent emergency surgery. While his current status is stable, he will be unavailable for work for an indefinite period, impacting upcoming casting and event schedules.
METI Holds Hearings on AI Voice and Likeness Misuse
On September 11, 2026, the Ministry of Economy, Trade and Industry (METI) convened the 30th Subcommittee on Prevention of Unfair Competition under the Industrial Structure Council Intellectual Property Division. The session focused on "Hearing from Related Parties Regarding Unauthorized Use of Likenesses and Voices by Generative AI." Voice actor groups and industry stakeholders presented data on damages and discussed the limitations of current laws in protecting performers against unauthorized AI cloning, marking a critical step toward potential legislative reform.
Ministry of Justice Publishes New Guidelines on AI Voice Infringement
In response to rising cases of unauthorized AI voice cloning, the Ministry of Justice released new guidelines clarifying rights infringement standards for AI-generated voices. The guidelines address cases where individuals monetize AI-simulated voices, with reports noting that some unauthorized content creators generate monthly revenues exceeding 750,000 yen. These guidelines aim to provide a clearer legal framework for prosecuting violations under unfair competition laws, offering a potential remedy for seiyuu whose voices are used without consent.
Local view
Japanese media outlets are closely monitoring the intersection of public safety and digital rights. Yomiuri Shimbun and TV Asahi have extensively covered the threats against Sumire Uesaka, emphasizing the need for stricter security protocols at fan events. Meanwhile, Nikkei Business and Branc are analyzing the government's recent regulatory moves, noting that the METI hearings and Ministry of Justice guidelines represent a shift from passive observation to active legal intervention in the AI voice sector. Local industry commentators view these developments as a necessary response to the "industrialization" of unauthorized voice cloning.
Context & numbers
The economic impact of AI voice misuse is becoming quantifiable. Recent data cited during the METI hearings and by Nikkei indicates that unauthorized AI voice content can generate significant revenue, with one case study revealing a monthly income of 750,000 yen for a single infringing account. This financial incentive drives the proliferation of unauthorized clones, challenging existing copyright frameworks which traditionally do not protect "voice" itself but rather recordings or performances. The industry is pushing for legal recognition of voice rights to combat this loss of control over personal branding.
