There is nothing holy about Christmas in Japan. The fact that they are also starting to celebrate Halloween is humorous to me. As far as America, you have one side that wants to remove the religious aspect of the holiday and the other that doesn't. (Keep Christ in Christmas.) The religious side is going to eventually lose and we will just be as bad as Japan. Celebrating just for the sake of celebrating.
Anyway I'm happy this single is going to end on a high note. Shame they won't be able to get a #1 to cap their time as a group.
