was imported from China during the Tang dynasty (618–907). The oldest example is Tamamushi Shrine at Hōryū-ji. flourished primarily in the 11th century and continued until the 13th or 14th century. After that, however, almost disappeared, due to the overall decline of Buddhist art.
Two pieces of leaf (gold or silver, platinum) are heated over an ash-banked fire and bonded together. An additional bonding is then done to further strengthen the leaf and add thickness. Next, the bonded leaf is cut with a bamboo knife on a deer-skin-covered table, then affixed with glue (seaweed glue, and glue,, etc.) to the object to be decorated.
