S/mileage

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). In February 2010, producer Tsunku announced S/mileage's challenge for their major debut. By the end of March, they were to collect 10,000 photos of people's smiles and assemble them on a 2 x 4 meter poster board.
