On the day of the performance, an altar is set up in Kagami no ma (literally, the "mirror room" behind Agemaku, or the curtain separating it and the stage, in which the fully-dressed performers don their masks and gaze into a large mirror to concentrate on their roles while they wait to enter the stage), and each actor purifies himself through Sakazuki-goto (the drinking of Omiki, or sacred sake) and with Kiribi (sacred sparks produced by rubbing together two pieces of wood, generally Hinoki, which is chamaecyparis obtusa, or by striking a flint against iron) before going on the stage.
当日は鏡の間に祭壇をしつらえ、舞台に上がる前に各役が盃事と切火で身を清める。
