Detective Conan is turning its 30th anime anniversary into a challenge for viewers. The franchise is making an audience-participation original anime, reported in English as The Misohitojima Murder, and the idea is simple: fans will try to identify the culprit alongside Conan instead of waiting for him to explain the answer. The project has no announced release date yet. Before it arrives, the anniversary has a firm date on the calendar. The 30th Murder Case, a new two-hour TV special, will air in Japan on September 25.
What is the audience-participation anime?
This is a new case separate from the September special. The announcement invites viewers to solve the mystery with Conan, then names Yasuichiro Yamamoto, a longtime Conan director, as the person who conceived the project. Takahiro Okura is writing the script. The staff has shown early concept art, but it has not explained exactly how the participation will work.
Will viewers get a pause to submit a theory? Will clues appear across a broadcast and an online companion? Could the production reveal how many fans picked the right culprit? Those details are still open, so it is better to describe the project as a mystery viewers solve alongside Conan than as an episode with different endings.
Why does this fit Detective Conan?
Since 1996, the series has made the audience part of every case. Viewers meet the suspects, hear competing explanations, and look for the small detail Conan notices before everyone else. The new project takes that familiar habit and puts it at the center of the format.
New viewers may know the series as Case Closed. Its hero is Shinichi Kudo, a high-school detective who was forced into a child’s body after being poisoned by the Black Organization. As Conan Edogawa, he keeps solving cases while searching for a way to return to normal. You do not need 30 years of episode knowledge to understand the hook; the format starts with a case and asks you to pay attention.
What is The 30th Murder Case?
The 30th Murder Case is the anniversary’s more traditional centerpiece, but it still has a large setup. It premieres on Friday Roadshow in Japan on September 25 from 9:00 to 10:54 p.m. local time, marking the first new Conan TV special in 10 years. The anime-original story is tied to counterfeit money and the release of a new 10,000-yen note.

Conan, the Detective Boys, Professor Agasa, Ran, and Sonoko visit the Japan Banknote Printing Bureau’s Nagano factory. Meanwhile, a murder scene produces counterfeit bills and the investigation spreads to Osaka, where Conan and Heiji follow the case.
Elaiza Ikeda joins as Toko Satomi, a specialist who examines documents and money to determine whether they are genuine. Nippon TV announcer Natsumi Kawade and Yomiuri TV announcer Hina Masuda also appear as TV announcers.
Is this a new direction or an anniversary one-off?
Probably both. The September special is a self-contained event for a major anniversary, while The Misohitojima Murder tests whether a long-running anime can make its audience part of the investigation. It is also a clean way to welcome different generations: longtime viewers can track the callbacks, and newer fans can focus on the case in front of them.
Yomiuri TV’s 30th-anniversary schedule includes other projects and special selections, but the audience-participation episode is the one that changes the viewing ritual. Instead of asking fans to debate the answer afterward, Conan is asking them to make the guess before the reveal.
When can fans watch them?
The 30th Murder Case has its Japanese broadcast on September 25. The participation project is still in production, and no air date or international availability has been announced. Readers should not expect an immediate streaming date or assume the interactive format will launch worldwide at the same time.
Once the staff explains how submissions and clues work, the project will be easier to judge. For now, the novelty is enough: an anime about a detective is giving its audience a more formal seat at the investigation.
Thirty years after Conan first took a case, the franchise is still looking for ways to make the mystery feel new. One anniversary special arrives September 25. The more unusual experiment is waiting behind it, asking fans to solve the next case before Conan does.
