Sokutai
The sokutai (束帯) is a traditional Japanese outfit worn only by courtiers, aristocrats and the emperor at the Japanese imperial court. The sokutai originated in the Heian period, and consists of a number of parts, including the ho (outer robe), shaku (笏), a flat ritual baton or sceptre, and the kanmuri (冠), a cap-shaped black lacquered silk hat with a pennon.
