When Did Detective Conan Start?
The Detective Conan anime first aired on January 8, 1996, on Nippon Television (NTV) in Japan. It was produced by TMS Entertainment and has been broadcasting ever since — making it one of the longest-running anime series in history.
But the story began even earlier. Creator Gosho Aoyama launched the Detective Conan manga in January 1994, in the pages of Shōnen Sunday magazine. The anime closely follows the manga's storyline, with new episodes continuing to air on a weekly basis even today.
Outside Japan, the show was adapted and aired under the title Case Closed — mainly in the United States — to avoid copyright conflicts with an existing property named Conan.
The Story of Conan Edogawa
At its heart, Detective Conan is the story of Shinichi Kudo, a brilliant 17-year-old high school detective regarded as the "Sherlock Holmes of the modern age." While investigating a suspicious deal at an amusement park, Shinichi is ambushed by two members of the criminal Black Organization. They force him to swallow a prototype poison called APTX 4869, expecting it to kill him — but it instead shrinks his body to that of a 6–7-year-old child.
To protect his loved ones and avoid being targeted again, Shinichi hides his true identity and adopts the alias Conan Edogawa — a name inspired by his two favorite mystery authors, Arthur Conan Doyle and Edogawa Ranpo. He moves in with his childhood friend (and love interest) Ran Mori and her bumbling detective father, Kogoro Mori.
"There is always only one truth." — Conan Edogawa's iconic phrase captures the soul of the entire series.
Using a series of gadgets created by the eccentric scientist Professor Agasa, Conan secretly solves case after case, making Kogoro look like a genius detective in the process. All while searching for the antidote to return to his real body and destroy the Black Organization.
Key Characters in Detective Conan
One of the reasons the series is so beloved is its rich cast of characters. Here are the most important ones:
- Conan Edogawa (Shinichi Kudo)
The protagonist. A genius detective trapped in a child's body after being poisoned by the Black Organization.
- Ran Mori
Shinichi's childhood friend and love interest. A karate expert who is unaware of Conan's true identity.
- Kogoro Mori
Ran's father and a private detective. Known as the "Sleeping Kogoro" since Conan solves his cases.
- Professor Agasa
Shinichi's neighbor and inventor who creates gadgets for Conan, including the Voice Changer and Bowtie.
- Ai Haibara
A former Black Organization scientist (Shiho Miyano) who also took APTX 4869 and shrank. Now an ally.
- The Detective Boys
Conan's classmates — Mitsuhiko, Ayumi, and Genta — who often get pulled into his investigations.
How Does Detective Conan Work? The Case Structure
Most episodes or episode arcs follow a self-contained mystery structure — often called "case-of-the-week" format. Conan stumbles upon a murder, robbery, or crime, gathers clues, deduces the culprit using his superior intellect, and then uses a tranquilizer dart to put Kogoro to sleep and speak through him using a voice-changing bowtie gadget.
Here's how a typical case unfolds:
- A crime occurs — usually a murder — in a seemingly ordinary setting
- Conan observes and analyzes the crime scene, paying attention to small details others miss
- Using deductive reasoning, he identifies the culprit
- He knocks Kogoro unconscious with a tranquilizer watch and disguises his voice
- The culprit is exposed through an elaborate and dramatic reveal
Interwoven between these standalone cases is the overarching Black Organization storyline — a complex, suspense-filled plot about a shadowy crime syndicate that Conan is determined to take down to reclaim his true identity.
Detective Conan Movies
Beyond the weekly episodes, the series has produced over 30 theatrical films, all released annually since 1997. Each film features a standalone, high-stakes adventure with polished animation and intense action. Notable entries include The Last Wizard of the Century, Crossroad in the Ancient Capital, and Zero the Enforcer. These films are beloved even by people who haven't watched the full series.
Why Is Detective Conan So Popular?
In an era where many anime come and go, Detective Conan has maintained a massive fanbase for over 28 years. Here's why it stands out among other best mystery anime titles:
- Intelligent writing: Each case requires genuine logic and deduction, rewarding attentive viewers
- Emotional depth: The romantic tension between Shinichi and Ran, and Conan's longing to return to his old life, adds heart to every episode
- Consistent quality: Despite being over 1,100 episodes long, the series has maintained quality writing and animation
- Cultural impact: Detective Conan has deeply influenced Japanese pop culture, spawning games, merchandise, a theme park attraction, and museum exhibits
- Broad appeal: It works for kids who enjoy adventure, teens who love puzzles, and adults who appreciate the thriller elements
The series is also praised by fans of classic literature — drawing clear inspiration from Arthur Conan Doyle's Sherlock Holmes stories, right down to Shinichi's pipe and deerstalker hat in certain appearances.
Where to Watch Detective Conan
If you're ready to start watching, several legal platforms carry Detective Conan. Crunchyroll offers a large library of episodes with subtitles. Netflix has it available in select regions. Physical DVDs and Blu-rays are also available, and the manga can be read on Viz Media's official platform.
Because the series is so long (over 1,100 episodes), new viewers are often encouraged to start with the first season and use episode guides to skip filler, focusing on canon and Black Organization-related episodes for the main storyline.
Will Detective Conan Ever End?
This is the question every fan asks. Creator Gosho Aoyama has confirmed that he knows exactly how the story will end — including the revelation of who runs the Black Organization and whether Shinichi Kudo returns to normal. However, due to the series' enduring commercial success, it continues to run with no confirmed end date.
The manga has been showing signs of approaching its finale in recent years, with major plot revelations and the advancement of the Black Organization arc, giving long-time fans hope that a proper conclusion is finally on the horizon.
Conclusion
Detective Conan is far more than just a long-running anime. It's a cultural institution — a masterclass in mystery storytelling that has kept fans hooked across generations. From its debut in 1996 to its ongoing run today, the series proves that great writing, compelling characters, and smart plotting never go out of style.
Whether you're a newcomer curious about Conan Edogawa or a returning fan brushing up on the lore, one thing is certain: once you enter Conan's world, there is always only one truth you'll find — that this anime is one of the best ever made.
