Bishoujo Senshi Sailor Moon (Pretty Soldier Sailor Moon) is a mahou shoujo, or magical girl, series that was first published in Japan as a serialized manga (comic) in a fantasy based magazine for young girls. Sailor Moon is a superhero adventure, drama, and romance all rolled into one. Its central theme is that love is the most powerful force in the universe, and that young women can shape their world using their emotional and physical courage.
Sailor Moon was the the first manga to combine two popular genres in Japanese pop culture: the magical girl genre of shoujo manga, and the shounen sentai action genre. This unique combination of seemingly opposing styles is what made it such an instant hit. Neither magical girl nor sentai stories exist in mainstream American comicbooks, but they've become popular imports following the manga explosion of the late 90's that was sparked by the popularity of Sailor Moon. In the spring of 1992, the appearance of the Sailor Moon series in books and on television gave birth to the new fantasy-action genre of girl battle teams.
The basis for Sailor Moon was a story called Codename wa Sailor V, which appeared as a special in Run-Run, a sister publication to the popular girls' manga magazine Nakayoshi ("Good Friend"). The author/artist of Sailor Moon and Sailor V, TAKEUCHI Naoko, had previously a number of short stories and romance series in Nakayoshi. The magazine is famous for publishing Sailor Moon, Card Captor Sakura, and many more popular girls' manga that became anime hits. In the summer of 1991, Naoko was drawing her longest serial to-date, The Cherry Project (3 volumes). For the launch of RunRun, she was given the offer to draw a one-shot story of anything she liked. She said she would like to try a superheroine story, as she was a big fan of "allies for justice" shows like tokusatsu heroes and sentai teams (see glossary). Her editor gave her the idea for "sailor-suited allies of justice" and the sailor-suited pretty soldier for justice, "Sailor V" was born. The seeraa fuku (sailor suit) is a popular symbol of the junior highschool girl in Japan, and using cute, colourful versions of school uniforms as battlesuits for the young superheroines was a guaranteed to catch the attention of young girls. Sailor Moon is firmly based in the magical girl tradition in which standard feminine items like school clothes, lockets, and beauty products are turned into powerful talismans for the magically endowed heroine.
Codename: Sailor V caught the eye of TV Asahi, who approached Naoko about turning her manga into a TV anime. The manga would be relaunched as a regular series in Nakayoshi while appearing simultaneously as a TV anime, for maximum cross-market exposure. A new, expanded series with an extended storyline was planned, what would debut in February 1992 as Bishoujo Senshi Sailor Moon. Early plans for the series were based on Sailor Venus, not Sailor Moon, as the main character, with a white cat and a masked man similar to Tuxedo Kamen. This was to be called Bishoujo Senshi Sailor V, as appears in this advertisement for the series that appeared in Nakayoshi the month before the series began.
While Sailor Moon became the star of the new series, Sailor V continued to appear simultaneously in her own prequel series. In addition to the monthly Sailor Moon chapters in Nakayoshi, Run-Run continued to periodically feature light-hearted Codename: Sailor V chapters of Minako's solo adventures as Sailor V, along with Artemis, that took place before she joined the Sailor Team. Once a year Naoko published a special "ChibiUsa's Picture Diary" chapter in Run-Run, later collected with the Sailor Moon tankoubon. In total, three volumes of Codename wa Sailor V were compiled, with the final Sailor V chapter being published in November 1997, 8 months after Sailor Moon ended. Translations of the entire series are available at The Manga of Takeuchi Naoko.
The above tagline is printed on the back of every Sailor Moon tankoubon (original edition). Bishoujo Senshi Sailormoon ran monthly in Nakayoshi, a monthly girls' magazine in Japan, from February 1992 to March 1997. A total of 52 installments were originally compiled into 18 tankoubon. The tankoubon also include the bonus side stories from Nakayoshi and its sister magazine Run-Run: 4 chapters of ChibiUsa's Picture Diary, the 3 "Exam Battles", Casablanca Memory, and The Lover of Princess Kaguya. Translations of the entire series are available at The Manga of Takeuchi Naoko. Due to the original tankoubon being out of print, the manga has been reprinted in new cover editions.
Five illustrations collections (artbooks) were released for Sailor Moon which collected the original color illustrations of each year drawn by Naoko for each chapter, supplements, Nakayoshi covers, etc. The artbooks also included new art. Each year of the manga has a corresponding artbook, the fifth being released a few months after the last chapter of Sailor Moon was published. There are no artbooks for Sailor V.
Following the completion of Sailor Moon and Sailor V, Naoko published a doujinshi artbook called The Original Art Collection of Sailor Moon: Volume Infinity. Volume Infinity is a collection of illustrations (color and B/W) and personal messages by herself and her friends reflecting their individual visions of Sailor Moon. This self-published book was printed in small numbers and distributed only in Japan at Comiket 1997 (Summer). In 1999 a memorial sketch book called the Sailor Moon Materials Collection was released. This is a collection of sketches and profiles of all the characters used in creating the manga. It also features a new, short manga story called "Parallel Sailor Moon" and some very lovely original illustrations.
