The Sailor Moon mythology is a fictional universe created by Naoko Takeuchi, blending elements of Japanese shōjo manga, Western astrology, and classical Greco-Roman and Norse mythology. The series follows Usagi Tsukino, a teenage girl who transforms into Sailor Moon, the reincarnated princess of the Moon Kingdom, and battles evil forces alongside her fellow Sailor Senshi.
Origins and Creation
Naoko Takeuchi conceived Sailor Moon in the early 1990s, initially inspired by the popularity of superhero teams and her own love of astronomy and classical myths. The manga debuted in 1991 in Nakayoshi magazine, and the anime followed in 1992. Takeuchi deliberately wove in planetary gods from Roman mythology—each Sailor Senshi is named after a planet and its corresponding Roman deity, such as Mars (god of war) and Jupiter (king of the gods). She also incorporated the Greek myth of Selene, the moon goddess, and the story of Endymion, a mortal shepherd loved by the moon, which forms the basis for Usagi and Mamoru’s past-life romance.
The Moon Kingdom and Silver Millennium
The central mythological backstory is the Silver Millennium, an ancient lunar civilization that flourished before the present-day story. Queen Serenity ruled the Moon Kingdom, and her daughter Princess Serenity (Usagi’s past life) fell in love with Prince Endymion of Earth, despite a taboo against such a union. The kingdom was destroyed by the Dark Kingdom, led by Queen Metaria, and Queen Serenity used the Silver Crystal to send her daughter and the other Senshi to be reborn on Earth in the future. This narrative mirrors the Greek myth of Selene and Endymion, where the moon goddess loved a mortal and visited him nightly, though the manga adds a tragic ending and reincarnation.
The Sailor Senshi and Their Planetary Gods
Each Sailor Senshi corresponds to a planet and its Roman deity, with powers and personality traits loosely tied to that god’s domain:
- Sailor Mercury (Ami Mizuno) – Mercury, the messenger god, associated with intelligence and water.
- Sailor Mars (Rei Hino) – Mars, god of war, with fire-based attacks and a shrine maiden heritage.
- Sailor Jupiter (Makoto Kino) – Jupiter, king of the gods, with lightning and strength.
- Sailor Venus (Minako Aino) – Venus, goddess of love and beauty, with love-based attacks.
- Sailor Uranus (Haruka Tenou) – Uranus, god of the sky, with air and sword-based powers.
- Sailor Neptune (Michiru Kaiou) – Neptune, god of the sea, with water and mirror abilities.
- Sailor Pluto (Setsuna Meioh) – Pluto, god of the underworld, controlling time and space.
- Sailor Saturn (Hotaru Tomoe) – Saturn, god of agriculture and time, with powers of destruction and rebirth.
These associations are not strict; Takeuchi adapted the myths to fit her story, giving each senshi a unique personality and role.
The Silver Crystal and the Legendary Artifacts
The Silver Crystal (also called the Legendary Silver Crystal) is the central MacGuffin of the series, a powerful gem that can create, heal, or destroy. It is linked to the Moon Kingdom and later to Usagi’s own power. In mythology, the moon is often associated with silver and feminine energy, and the crystal’s ability to grant wishes echoes the myth of the Moon’s influence on tides and fertility. Other artifacts include the Ginzuishou (the Japanese name for the Silver Crystal) and the Holy Grail, which appears in the third arc as a vessel for the Holy Moon Chalice. These items draw on both Eastern and Western mystical traditions, but their specific powers are original to the series.
Villains and Their Mythological Roots
The antagonists in Sailor Moon often have names and themes from various mythologies. Queen Beryl, the primary villain of the first arc, is named after the gemstone beryl, and her Dark Kingdom is a shadowy counterpart to the Moon Kingdom. The Dark Kingdom’s generals are named after minerals (Jadeite, Nephrite, Zoisite, Kunzite), not mythological figures. Later arcs introduce the Black Moon Clan, which references the concept of a dark moon, and the Death Busters, whose leader Pharaoh 90 is named after a number, not a myth. The Sailor Starlights in the final arc are named after the stars Sirius, Canopus, and Polaris, reflecting Takeuchi’s interest in astronomy. The use of planetary and stellar names is consistent, but the mythological depth is mostly superficial—Takeuchi uses the names for aesthetic and symbolic resonance rather than strict adherence to the original myths.
Reincarnation and the Cycle of Souls
A core theme in Sailor Moon is reincarnation, which is not a standard element of Greco-Roman mythology but is common in Eastern religions like Buddhism and Hinduism. The Senshi are reborn in the 20th century with memories of their past lives, and they must regain their powers to fight evil. This cycle of death and rebirth is central to the plot, and it is also reflected in the character of Sailor Pluto, who guards the Time-Space Door and can manipulate time. The idea of souls being reborn to fulfill a destiny is a modern invention by Takeuchi, blending Japanese Buddhist concepts with Western fantasy tropes.
Common Misconceptions
A frequent misconception is that Sailor Moon is directly based on Greek mythology, but it is more accurate to say it is inspired by a mix of sources. The series also draws on Japanese folklore—for example, the youma (demons) and the shrine setting for Rei Hino. Another misconception is that the Sailor Senshi are goddesses; they are not, they are ordinary girls with magical powers derived from their planetary guardians. The mythology is a pastiche, not a faithful retelling, and the names are chosen for their sound and symbolic associations rather than their mythological accuracy.
Frequently Asked Questions
Is Sailor Moon based on Greek mythology? Partly. The names of the planets and their gods come from Roman/Greek mythology, and the story of Princess Serenity and Endymion is inspired by the Greek myth of Selene and Endymion. However, the series also uses Japanese folklore, Buddhism, and original inventions.
Why is Usagi called Sailor Moon? Usagi’s name means ‘rabbit’ in Japanese, a nod to the rabbit-in-the-moon folklore. Her title as Sailor Moon comes from her role as the guardian of the Moon Kingdom, and her powers are tied to the moon and the Silver Crystal.
Are the Sailor Senshi based on real gods? They are named after Roman gods, but they are not the gods themselves. Each senshi embodies certain traits of their corresponding deity, such as Mars’s fiery temper or Venus’s beauty, but they are original characters with their own personalities and stories.
What is the Silver Millennium? The Silver Millennium is the ancient lunar civilization that existed before the present story. It was ruled by Queen Serenity and was destroyed by the Dark Kingdom, leading to the reincarnation of the princess and her guardians on Earth.
Does Sailor Moon have any connection to Japanese mythology? Yes, there are elements of Japanese folklore, such as the rabbit on the moon, shrine maidens (miko), and the concept of youkai. The series also incorporates Buddhist ideas of reincarnation and karma, though these are adapted to fit the narrative.
