Japanese officialdom often uses the year of the emperor. 2008 is Heisei 20. So Gumdrop's Shaken sticker refers to 2007, while her road tax sticker refers to 2006. Looks like the last Japanese owner decided to sell out before the next Shaken, since Gumdrop was at Japanoid's facility in Japan in July 2007.
