Nana

Nana (stylized as NANA) is a Japanese manga series written and illustrated by Ai Yazawa. First published as a two-part prologue in Shueisha's monthly shōjo manga magazine Cookie in 1999, Nana was later serialized in the same magazine from May 2000 to May 2009 before going on indefinite hiatus. Its chapters have been collected in 21 tankōbon volumes. The series centers on Nana Osaki and Nana Komatsu, two women who move to Tokyo at the age of 20, with the story focused on Nana O.'s pursuit for fame and Nana K.'s pursuit for romance, all while struggling to maintain their friendship.

The manga was adapted into a live-action film in 2005, with a sequel released in 2006. A 47-episode anime television series adaptation, produced by Madhouse and directed by Morio Asaka, aired on Nippon TV between April 2006 and March 2007. All Nana media has been licensed for English language release in North America by Viz Media, which serialized the manga in their Shojo Beat magazine until the August 2007 issue, while also publishing it in the tankōbon format. They released both films in 2008, and their English dub of the anime was broadcast on the Funimation Channel beginning in 2009. The anime series was later re-licensed by Sentai Filmworks in 2021.
