The Sailor Moon manga series (美少女戦士セーラームーン, Bishōjo Senshi Sērā Mūn, Pretty Soldier Sailor Moon) was the first version of what would eventually become the media franchise known simply as Sailor Moon. It was created by Japanese artist Naoko Takeuchi and debuted in Nakayoshi magazine in December 1991. It continued to be serialized by Nakayoshi throughout its five-year run, except for certain side-stories which appeared in Kodansha's Run Run. The book collections were all published by Kodansha.
