1. Noh masks can change their expression
By different accounts, there are anywhere from 60 to 200 different types of mask used in today’s Noh performances. Actors treat masks with the reverence of elders and will bow when handling them. Many Noh masks have a neutral expression which can change their emotion through shadow and relief depending on whether the actor tilts them upwards or downwards. In most Noh plays, it is generally the shite, or principle character, who wears a mask. Masks are deliberately smaller than the actor’s face to show the unity between the actor and the character.
