Hello! Project

Hello! Project ,often shortened to H!P, is the name for a collection of female groups and artists all produced by Tsunku, a member of Sharam Q. Morning Musume is the main group of Hello! Project, with a number of  Morning Musume ex-members forming the majority of the solo artists in H!P. Besides the core groups and solo artists that form H!P's line-up, various special units are formed by mixing these groups and solo artists. Shuffle units, usually formed by shuffling all the H!P members into three temporary units, were formed once a year but since 2006 the idea has been dropped.
