Mother-of-pearl inlay (Raden)

Mother-of-pearl inlay (Raden) is a decorative technique that uses the iridescent inner layer of abalone shell, turban shell, pearl oyster shell, or other mollusk shells. The technique came to Japan from China 1,300 years ago, and pieces featuring mother-of-pearl inlay are included among the artifacts at the Shōsōin Repository in Nara.
