Seiyuu: Casting, Concerts and Industry Fights — 2026-09-26
The past week brought a worrying safety incident for voice actress Sumire Uesaka, who filed a police report over threats and withdrew from events, while Japan's Ministry of Justice guidance on AI voice imitation continues to reshape the debate over unauthorized voice cloning. Overseas, SAG-AFTRA game performers overwhelmingly backed a new strike authorization with AI demands at the center. The fall 2026 anime season cast lineups are being tallied by Japanese fansites ahead of October premieres.

Sumire Uesaka files police complaint over threats, withdraws from events
Voice actress Sumire Uesaka reported submitting a victim complaint (被害届) to police after receiving threatening conduct, announcing she is withdrawing from an scheduled event and pausing SNS activity, according to Sports Nippon (via Infoseek, published September 24, 2026). The case highlights the growing fan-harassment and safety burden on seiyuu, who regularly appear at face-facing live events.
SAG-AFTRA game performers authorize strike with AI demands in focus
On September 24, 2026, 34,687 SAG-AFTRA game performers voted overwhelmingly — reportedly 98.32% of participating voters — to authorize a strike against major video game companies, with demands around AI protections cited as the core issue. The move follows the union's earlier 2025 game contract that included AI safeguards, and its June 2026 ratification of a four-year studio contract with AI terms, suggesting performers want tougher enforcement rather than new language. Japanese seiyuu and English dub actors operate in increasingly parallel AI fights, making this a bellwether for global voice-performer organizing.
Ministry of Justice AI-voice guidance keeps pressure on legal gaps
Nikkei Business reported on the Justice Ministry's published guidance arguing that AI imitation of voices can constitute rights infringement, citing a poster who earned ¥750,000 per month from AI-voice content — a figure that frames the scale of unauthorized monetization at stake for voice performers. The guidance came amid submissions to METI's unfair-competition subcommittee from the Japan Actors Union (日俳連), volunteer seiyuu groups and the voice-actor agency association (声事協), which presented damage estimates and called current law insufficient.
Fall 2026 season casts tallied ahead of October premieres
With October shows about to premiere, Animate Times published its recurring "picking anime by voice actor" roundup of fall 2026 seiyuu roles, and a fan blog (September 25) compiled male voice actors taking their first main roles this season — a useful gauge of the debut pipeline agencies are pushing.
Kito Akari dubs for "VIVANT" star
Hochi (September 23, 2026) reported that popular voice actress Akari Kito — known for Nezuko in Demon Slayer — is handling dubbing work related to the "VIVANT" choqued co-star, with the actor sharing a photo and saying he is "really fond" of the collaboration. It's a reminder of seiyuu's growing crossover value in live-action dubbing and promotional media.
Local view
Japanese entertainment press is focused on the Uesaka threats — Sports Nippon led the reporting of her police complaint and event withdrawal, framing it as part of a broader pattern of harassment affecting performers. Meanwhile, Kyoto CMEX (September 24) promoted a lecture series at Kyoto Tachibana University running September 26 to December 12 on "voice copyright" in the generative-AI era, showing academia joining the industry's push to define voice rights.
Context & numbers
- ¥750,000 per month: the earnings of one reported AI-voice content seller cited in the Justice Ministry-related coverage, illustrating unauthorized monetization at issue.

- The Kyoto Tachibana University lecture series on voice copyright runs September 26 – December 12; watch for policy takeaways.
- NYCC (October 8–11) will host Hikaru Midorikawa and other Japanese guests — likely source of new cast/convention news next week.
