Kanmuri literally translates to ‘Crowning Trim,’ therefore, it originally was a hat worn by the Japanese kings and aristocrats. However, now it is only worn by the clergies of the Shinto religion. It is a formal hat and is therefore worn with the formal attire comprising the Jōe for ceremonial occasions such as Taisai or Chûsai.
Kanmuri is a round brimless cap with a tall knob at the back. A wooden crossbar is attached at the back of the knob, and a thin lacquered or slightly transparent strip of cloth or a tail is attached at the back of this crossbar. Kanmuri is always black.
There are rhomb patterns on the tail. The number of rhombs defines the priests’ ranks; the higher the number, the better the rank.
