One type of kazura, or wig, worn by the performers. Traditionally made of yak hair. The bangs are worn draped across the forehead, with the hair falling to the shoulders and long down the back. The hair of the kurogashira is black, giving it its name. In Noh, this mask is traditionally worn by the roles of spirits such as the dōji or onryō, and in kyōgen, by ghosts or livestock. In addition to the kurogashira, there are akagashira and shirogashira (red and white kashira), which are also used depending on the role and performance. Kurogashira is also the name of a kogaki, indicating a special performance.
