Case Closed, also known as Detective Conan (Japanese: 名探偵コナン, Hepburn: Meitantei Konan, lit. 'Great Detective Conan'), is a Japanese detective manga series written and illustrated by Gosho Aoyama. It has been serialized in Shogakukan's shōnen manga magazine Weekly Shōnen Sunday since January 1994, with its chapters collected in 105 tankōbon volumes as of April 2024. Due to legal problems with the name Detective Conan, the English language releases from Funimation and Viz Media were renamed to 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. The manga was adapted into an anime television series by Yomiuri Telecasting Corporation and TMS Entertainment, which premiered in January 1996. The anime resulted in animated feature films, original video animations, video games, audio disc releases and live action episodes. Funimation licensed the anime series for North American broadcast in 2003 under the name Case Closed with the characters given Americanized names. The anime premiered on Adult Swim but was discontinued due to low ratings. In March 2013, Funimation began streaming their licensed episodes of Case Closed; Crunchyroll simulcast them in 2014. Funimation also localized the first six Case Closed films, while Discotek Media localized the Lupin III crossover special, its film sequel, and select recent films, starting with Case Closed Episode One. Meanwhile, the manga was localized by Viz Media, which used Funimation's changed title and character names. Shogakukan Asia made its own localized English version of the manga, which used the original title and Japanese names. The tankōbon volumes of the manga had over 270 million copies in circulation worldwide by January 2023, making it the third best-selling manga series of all time. In 2001, the manga was awarded the 46th Shogakukan Manga Award in the shōnen category. The anime adaptation has been well received and ranked in the top twenty in Animage's polls between 1996 and 2001. In the Japanese anime television ranking, Case Closed episodes ranked in the top six weekly. Both the manga and the anime have had a positive response from critics for their plot and cases. The manga has been sold in 25 countries, while the anime has been broadcast in 40 countries.
