The Shōwa Emperor
on his enthronement ceremony wearing a sokutai
and holding a shaku
The sokutai (束帯) is complex attire only worn by courtiers, aristocrats and the emperor at the court in Japan. Part of a sokutai are the shaku (笏), a flat ritual baton or sceptre, and a hat called kanmuri (冠) (see photo).
No longer in normal use, the sokutai is however still worn by imperial court members and government officials (including the Prime Minister) on rare occasions such as weddings and enthronement ceremonies.
