Roundel of dark blue silk cut from an Emperor's or Prince's surcoat, formed out of two hemispheric panels. It is embroidered in coloured silk and silver threads in long and short, satin and stem stitches with couched work. It bears a front-facing five-clawed dragon encircling a flaming jewel, amidst clouds, bats and swastikas with sea waves below. The sun is one of the twelve imperial symbols.
Frame is a latter-day addition.
