For the characters to change masks, costumes, etc., they often enter the curtain or go behind the piece of scenery and leave the stage for a moment. This action is called nakairi. The main character is called shite, and the shite before nakairi is called mae-shite, and one after nakairi is called nochi-shite, respectively. It is a rule that the same actor performs both mae-shite and nochi-shite. Sometimes they are pronounced "mae-jite" as well. Tsure, waki and kyōgen are similarly called when nakairi is featured.
