Kanmuri - a classic court cap, made of lacquered wood and paper. It is traditionally made by creating a skeleton, or harinuki, of paper on a wooden form. The outside of the hari-nuki is lacquered so as to keep its shape, and then the body of ra silk is layed on top. The entire thing is lacquered stiff.
