Detective Conan

Case Closed, also officially known as Detective Conan (Japanese: 名探偵コナン, Hepburn: Meitantei Konan; lit. 'Great Detective Conan'), is a Japanese manga series written and illustrated by Gosho Aoyama. It has been serialized in Shogakukan's shōnen manga magazine Weekly Shōnen Sunday since January 1994; its chapters have been collected in 108 tankōbon volumes as of April 2026. Because of legal problems with the name Detective Conan, several American English language releases were renamed Case Closed. The story follows the high school detective Shinichi Kudo, whose body was transformed into that of an elementary school-age child while investigating a mysterious organization. Generally, he solves a multitude of cases by impersonating his childhood best friend's father and various other characters.

Case Closed is licensed for English-language release in North America by Viz Media, which has published the manga in print since September 2004. It also publishes the series in English on the Viz Manga digital manga service, with the series' chapters receiving simultaneous English publication in North America as they are released in Japan. Shogakukan Asia publishes the manga in English in Singapore and in the Southeast Asian region. It has been adapted into an anime television series adaptation produced by Yomiuri Telecasting Corporation and TMS Entertainment, which began broadcasting in January 1996.
