Konin Todoke Seisakujo/Design Laboratory for Marriage Paperworks has offered various types of marriage registration papers inspired by the Sailor Moon Crystal anime franchise.
The company started offering marriage papers using images of poplar characters, such as Hello Kitty, One Piece, and Hatsune Miku, since November 2014.
The papers have been purchased/downloaded over 16,000 times per month, which is about 30 percent of the monthly number of marriage registrations in Japan.
