In 2004, W's formation was announced not long after Nozomi Tsuji and Ai Kago's graduations from Morning Musume. Tsuji and Kago had previously worked together in one of Morning Musume's sub-units, Mini Moni, as a side project. Both members had been known as the "Twins" and had been some of Morning Musume's most popular members since joining the group at age 12. Tsunku, Hello! Project's producer, had selected the name "W" because the origin of the name meant "two Us" and "gave off the feeling of two You's", symbolizing Tsuji and Kago's dual nature.
