A cord used to secure a crown, such as a tenkan worn by a heavenly maiden or a wa-kammuri used for the role of a male deity, to the head of the performer. One cord end is split into two, resembling the letter Y. To secure the line to the crown, the cord is passed through the two small holes on each crown side and tied inside. To secure the crown to the head, the cord attached to the crown is tied under the chin. It consists of silk that can be tied tightly without loosening and uses a round braid with a circular cross-section. Two strings make a set. The colour is primarily purple, but there are also others.
