S/mileage (スマイレージ) is a Japanese pop group under the Hello! Project umbrella. It is entirely made up of Hello! Project Eggs, who were mostly part of the Egg unit しゅごキャラエッグ! as well. The group had its indie debut in June 2009 with the single "aMa no jaku" (ぁまのじゃく) and appeared as backdancers in 真野恵里菜's music videos and performances. In February 2010, producer Tsunku challenged the group to collect 10 000 smiles hereby launching an Internet campaign in which fans had to send their picture to the group to be glued by the girls on a mosaic.
