- Japanese: 螺鈿 (raden)
Raden, or mother-of-pearl inlay, is a style and technique frequently used in lacquerware decoration. It involves inlaying or otherwise affixing onto the lacquerware object cut sections of abalone or turban shell (turbo marmoratus, J: yakôgai 夜光貝), which have been ground to roughly 1mm in thickness, forming a thin shimmering rainbow-colored material. The technique is widely used throughout the East Asian region.
