In celebration of the one-year anniversary of the collaboration between Japan’s "Empress of Pop" Ayumi Hamasaki and Sanrio, limited-edition products such as stationery and keychains have been produced, called "Premium Countdown Live" items!

The products feature Ayumi Hamasaki’s cartoon version Ayupan wearing a Hello Kitty hat. Some of the products feature distinctive logos that highlight both icons, like the presence of the red bow Hello Kitty is known for, or Ayumi Hamasaki’s trademark.
