Kumiko is a traditional Japanese woodworking technique used to create intricate lattice patterns or grids, typically found in sliding doors, room dividers (shoji), and decorative screens. Kumiko patterns are constructed by interlocking small wooden pieces without the use of nails or glue, relying solely on precise joinery and craftsmanship.

The process involves cutting and assembling thin wooden strips (often made of Japanese cypress) into various geometric shapes, such as squares, diamonds, or hexagons. These pieces are then fitted together to form the desired pattern, creating a visually stunning effect that allows diffused light to pass through while providing privacy.

Kumiko craftsmanship requires a high level of skill, patience, and attention to detail, making it a revered art form in Japan. It has been practiced for centuries and continues to be appreciated for its beauty and craftsmanship in both traditional and modern architectural design.
