Nogetsugi

Nogetsugi, known in English as fretwork joints, features intricate interlocking joinery used in Japanese architectural woodwork. With this technique, ornate segments are cut from the end grain of a beam or stile, leaving an asymmetric pattern somewhat resembling leaves on a branch. Complementary fretwork patterns are then chiseled into the adjoining post or rail. When fitted together, the radial grain of each beam segment crosses diagonally with the tangential grain of the surrounding wood, locking the pieces firmly. Called nogetsugi meaning "entwined branches", this counter-grained bonding strengthens the joint while creating decorative fissures. Nogetsugi adorned architectural fixtures like shoji screens and castle gates, enduring centuries through layered reinforcement of opposing wood fibers in its artful cross-graining techniques.
