Center
The term Center (センター） is used to describe the main member in that single's senbatsu. The 'center' gets center position in the formation of the members, and also gets most media exposure for that single.
The 'center' format is not always used in singles, so the center could be shared between two people - known as a W Center （Wセンター）- or the single could have no center and fairly distribute the position between different members.
In order to vary the center, the center position can be won at the Senbatsu Sousenkyo, and also at the Janken Taikai.
