The complementary gold and silver threads were created with the following technique: sheets of mulberry paper were covered with a layer of lacquer and a secondary layer of gold or silver leaf and then cut into extremely thin strips, the width varying depending on the desired weave. These composite brocade fabrics were called kinran.
This technique spread throughout Japan in the 14th century, following its introduction by a community of Chinese artisans who had relocated to the city of Sakai, close to Osaka.
