It all started with a small black cat with a lot to say, and a young girl named Usagi Tsukino who received a brooch that transforms her into the titular Sailor Moon. From that point forward a team of Sailor Guardians becomes assembled, and they’re out to save the world from all the enemies that come their way. International Sailor Moon Day celebrates this incredibly popular manga and the anime series that was birthed from it, so get out there and get your Guardian on!

History of International Sailor Moon Day

The date of International Sailor Moon Day is a subtle test to determine just how much of a fan you really are. Rather than the obvious choice of Sailor Moon’s birthday or the day the manga was first created, it’s set on the birthday of Mamoru’s birthday! It makes perfect sense considering that he’s the Prince of Earth and represents us all. Sailor Moon is so popular that it has garnered an international following, originally being published in Japan in 1991 it had over one million copies sold by 1995, and the number just kept growing over the next couple decades. Now it’s loved the world over, both in its manga and its anime format, and it has sold over 35 million copies in fifty countries, that’s some serious Sailor love right there!

Speaking of Sailor Love, Sailor Moon (the manga) has stood as a strong symbol for the LGBTQ communities thanks to its “naturalization” of lesbianism, a result of the futuristic setting and the goals of its creators to show equality in its writing. It’s been said to emphasize a particular feminist model by “combining traditional masculine action with traditional female affection and sexuality”, a truly daring advance by its writers and fans considering the year it was made.

How to celebrate International Sailor Moon Day

The first and best way to celebrate International Sailor Moon Day is to bust out your DVDs of all the seasons (you know you have them!) or go to a place like Hulu or Netflix to find them available and marathon the day away with your favorite show! Take it to the next level by dressing up as your favorite character, it doesn’t just have to be the eponymous Sailor Moon! You could dress up as Tuxedo Mask, or Sailor Mercury, whichever one happens to match your personality best, or just has your favorite outfit. Don’t be afraid to cross-dress, there’s no shame in celebrating your character by dressing up as them, regardless of your gender!
