One type of headwear in Noh and kyōgen. The sumibōshi, or “angled hat,” is worn by monk roles, with the top folded into a triangle and the rear draped down the back of the performer. The part of the hat draped down the back is folded upwards, and when that portion is used to cover the side of the face, it is known as “to wear in the shamon style” or “shamon bōshi,” and is used for the roles of high priests. It is also known as the sunbōshi.
