7 Seeds (stylized as 7SEEDS) is a Japanese manga series written and illustrated by Yumi Tamura. It is set in a post-apocalyptic future, long enough after a meteorite hits Earth that new species have evolved, and follows the struggles of five groups of young adults to survive after they are revived from cryonic preservation. The title comes from five groups of individuals in cryogenic chambers along with supplies, called "seeds", laid down by the Japanese government.
The manga was originally serialized in Shogakukan's Bessatsu Shōjo Comic magazine, premiering in the November 2001 issue; it transferred to Flowers magazine in April 2002, where it ran until its conclusion in May 2017. Shogakukan collected the individual chapters into 35 bound volumes.
An original net animation (ONA) adaptation, produced by Gonzo and directed by Yukio Takahashi, was announced in November 2018. The first season was released worldwide on Netflix in June 2019. A second season produced by Studio Kai premiered on 26 March 2020.
In 2007, 7 Seeds won the 52nd Shogakukan Manga Award for the shōjo category. Including digital sales, it has sold more than 6 million copies in Japan.
