What is Shikkoku?
Shikkoku is the iconic jet black of Japanese lacquerware, created by mixing purified urushi with iron powders. The result is a surface that absorbs light while maintaining a deep, mirror-like gloss.
This rich black serves as the foundation for traditional decoration techniques such as maki-e (sprinkled gold or silver), chinkin (carved lines filled with metal), and raden (shell inlay). Built through multiple layers and careful polishing, shikkoku creates a depth that feels almost endless.
More than a color, shikkoku is a cornerstone of Japanese lacquer art. Many works on view at Onishi Gallery employ this technique—visit us to experience it in person.
