A form of headgear, used by high-ranking characters such as gods, emperors, and nobles. Different types of the elongated "ei (tail)" are positioned behind the crown in line with the role, with civil servants using a curved, hanging tail, and military officers a rolled tail. For a rolled tail, oikake (ornaments knitted with horsetail hair in a fan shape) are attached to the left and right of the crown. The use of ui-kammuri depends on the performance. A crown with sukibitai (a half-moon shaped instep) is used for a young man who has just become an adult. Sometimes, plants are inserted that are symbolic of the program.
