Plot

Jimmy Kudo (Japanese name: Shinichi Kudo) is a high school detective who sometimes works with police to solve cases. During an investigation, he is ambushed and incapacitated by a member of a crime syndicate known as the Black Organization. In an attempt to murder the young detective, they force-feed him a dangerous experimental drug. However, instead of killing him, it shrinks his body to the size of an elementary school child. Adopting the pseudonym Conan Edogawa, Kudo lives with his childhood friend Rachel Moore (Ran Mori) and her father, Richard (Kogoro Mori), who is a private detective. Kudo keeps his real identity secret from most people, but early on confides in family friend and inventor Dr. Agasa, who supplies Kudo with an array of spy gadgets. Throughout the series, young Kudo tags along on Richard's cases. Kudo typically solves them, revealing the culprit by sedating Richard with a tranquilizer dart from his wristwatch and copying Richard's voice with a bowtie gadget. This ruse helps Kudo maintain his cover, but also gives Richard the reputation as a brilliant but narcoleptic detective. Kudo also enrolls in Teitan Elementary School, where he makes friends with a group of classmates who form their own Junior Detective League (Detective Boys). While he continues to dig deeper into the Black Organization, he frequently interacts with other characters, including his neighbor, Dr. Agasa; Rachel's friend Serena Sebastian (Sonoko Suzuki); a fellow teenage detective, Harley Hartwell (Heiji Hattori); assorted police detectives from different regions; and a phantom thief called Kaito Kid.

Kudo later encounters an elementary school transfer student, Anita Hailey (Ai Haibara), who reveals herself to be a former member of the Black Organization under the code name Sherry and the creator of the experimental drug that shrunk him. She too ingested it to evade the pursuit of the organization. She soon joins the Junior Detectives. During a rare encounter with the Black Organization, Conan helps the FBI plant a CIA agent, Kir, inside the Black Organization as a spy.

Production

Case Closed was conceived when Gosho Aoyama was asked to create a mystery manga. This was during the rise of the genre in manga due to the publishing of The Kindaichi Case Files (1992). Aoyama cites the stories of Arsène Lupin, Sherlock Holmes and the samurai films by Akira Kurosawa as influences on his work. Wanting to have a unique element, he came up with "shrinking" a skilled detective. In 2007, he explained that he does not get tired of the series because the mysteries allow him to portray a variety of genres. "If the criminal is an athlete, it feels like a sports story. If they're an actor, it feels like a stage drama. Every time I work with a different world, so it lets me draw things in a way that keeps the story feeling fresh." An online database of all the cases from the manga was launched that year.

Each case spans several chapters (except for a handful of shorter cases that span only one) and is resolved at the end, when characters explain the details of their solutions in simple terms. Aoyama researches and conceives of the "tricks" to the cases together with his editors, which includes testing some of the science experiments and magic tricks himself. His older brother is a scientist who also helps him with the "gimmicks" in the series. With the story and trick determined in meetings with the editors, Aoyama then spends hours in isolation by himself, thinking of the best way to show them in the storyboard. When he starts drawing a rough draft, he considers how much romantic comedy, mystery and human drama to include. When scripting each chapter, he ensures the dialogue remains simple and spends an average of four hours for each new case and twelve for more complicated ones.

In 2007, Aoyama hinted that he had planned an ending but did not intend to end the series yet. Aoyama and his staff decided to computerize their manga creation process in early 2011, although he still draws with a pen and paper. The change began with the final page of chapter 760. In 2015, Aoyama was hospitalized for a surgery, resulting in Case Closed going on its first lengthy hiatus in 21 years. The following year, he reduced his workload by less than half. As of 2023, it took Aoyama two months to create a 64-page story spanning four chapters, with him working 18-hour days. In 2026, Aoyama revealed that he had already drafted the thumbnail layouts (name in Japanese) for the final chapter.

Manga

Written and illustrated by Gosho Aoyama, Case Closed started its serialization in Shogakukan's shōnen manga magazine Weekly Shōnen Sunday on January 5, 1994.

As of April 8, 2026, 108 volumes have been published.

Viz Media announced its acquisition of the series for North America on June 1, 2004. Following Funimation's localization, Viz released the series as Case Closed and took their character names to keep consistency between the two media.

On May 9, 2023, Viz Media launched their Viz Manga digital manga service, with the series' chapters receiving simultaneous English publication in North America as they are released in Japan.

Gollancz licensed and distributed 15 of Viz Media's volumes in the United Kingdom before ceasing publication of manga. (Viz Media has since re-released them). In 2014 Shogakukan Asia began its own English localization of the series for Singapore and other Southeast Asian countries as Detective Conan. Laura Thornton of CBR.com, citing the common Japanese ownership in both Shogakukan Asia and Viz, described the Singapore version as, compared to the Viz one, "completely identical, word-for-word, even -- save for the names and the Detective Conan logo".

Critical response

Sparrow for its stories—telling the mysteries and how they were unfolded by the investigations of Conan and gang. Sparrow called the style of the series a mix of Scooby-Doo and Sherlock Holmes, while Chavez believed the manga had appeal to readers of all ages. Melissa Sternenberg from THEM Anime Reviews gave the series 5 out of 5 stars, she praised its animation and plot, and described it as "what puts Detective Conan as my all-time favorite anime is the superb writing. I soak up Detective Conan like a good book, I get so drawn into every episode that everything around me just sinks away and it is just me and the episode. It is engrossing. I can not think of another word for it. Like I said, every episode is fresh, and every mystery that is solved is profound. The kid is a prodigy, and you can not blink while watching an episode of this wonderful series".

ActiveAnime's reviewers commented on complex character design and the "spirit" that the series has, indicating that fans of serialized mystery shows would rather enjoy it.
