sokutai
Japanese court apparel worn by courtiers, aristocrats, and the Japanese emperor during the Heian period. Though no longer worn as everyday clothing, the outfit is still used for especially formal occasions such as weddings and enthronement ceremonies. Not to be confused with kariginu.
The outfit consists of several parts, most notably the kanmuri (tate eboshi), hou (an outer robe), and shaku (a ritual baton).
