A television anime adaptation titled Azumanga Daioh: the Animation was produced by J.C.Staff and aired in Japan between April and September 2002, consisting of 130 five-minute segments compiled into 26 episodes. The compiled episodes were released on DVD and Universal Media Discs (UMDs) by Starchild Records, and an English-language version was produced by ADV Films. Prior to the series, a theatrical short and an original net animation were also produced. Several soundtrack albums were released, as well as three Azumanga Daioh video games.
The anime television series, Azumanga Daioh: the Animation, was produced by J.C.Staff and aired from the week of April 8, 2002 until the week of September 30, 2002. It was broadcast on TV Tokyo, TV Aichi, TV Osaka, and AT-X in five-minute segments every weekday, then repeated as a 25-minute compilation that weekend, for a total of 130 five-minute segments collected in 26 episodes. For the compilation episodes, the respective opening and ending themes were “Soramimi Cake” (Cake of Mishearing) and “Raspberry Heaven”, both performed by Oranges & Lemons. The compilation episodes, which were the only versions to include the title and credits sequences, were released on 6 DVDs in 2003 and 9 Universal Media Discs between 2005 and 2006 by Starchild Records, and a DVD box set of all episodes was released on June 24, 2009; the five-minute segments can be distinguished by their individual titles.
Besides the anime television series, there have been two other animated adaptations: The Very Short Azumanga Daioh Movie, a six-minute trailer released to movie theaters to publicize the upcoming television series, and Azumanga Web Daioh, a shorter original net animation made available for paid streaming on chara-ani.com beginning from December 28, 2000, then offered as a paid download for a limited time. Azumanga Web Daioh was originally intended to gauge whether there was enough interest to create a web-released anime adaptation; because of overwhelming demand, the original plan for web-release was changed to a television release. It featured different voice actors and music from the regular series.
In the United States, the anime television series was released in six DVDs on September 9, 2005, and then later in a five DVD volume “Thinpak” set, both by ADV Films. The sixth DVD volume included The Very Short Azumanga Daioh Movie. In 2009, Nokia offered the first five episodes of Azumanga Daioh on its Ovi phone service. Madman Entertainment licensed the series for release in Australia and New Zealand. As of September 1, 2009, all of ADV’s former catalog are transferred to AEsir Holdings, with distribution from Section23 Films. The series was later re-licensed in 2016 by Sentai Filmworks.
