One type of headdress worn by Shinto priests (shinshoku) during ritual ceremonies. Originally a headdress worn to indicate a man who had passed his "coming of age" ceremony (genpuku), the eboshi evolved into heavily lacquered and other various formalized types from the late Heian period; from the early modern period it was rarely worn outside of ritual occasions. Shinto vestments include three types, "formal vestments" (seisō), "ritual vestments" (reisō), and "ordinary vestments" (jōsō); of these, the eboshi is worn by male priests as part of the class of "ordinary vestments" which includes the robes called kariginu and jōe. (See Seisō, reisō , jōsō.).
