Kigumi is the traditional Japanese carpentry technique of joining timber with interlocking wooden joints, developed over generations of master carpenters without nails or adhesives. It represents accumulated, hands-on craft knowledge rather than formal design theory.
The traditional Japanese carpentry technique of kigumi serves as a prime example of a vernacular procedure. This intricate system of interlocking wooden joints, developed over centuries and passed down through generations of master carpenters (daiku), allows for the construction of complex timber structures without the use of nails, screws, or adhesives. The procedures for measuring, cutting, and fitting these joints are not derived from modern, formalized design theory but represent a form of accumulated, embodied wisdom.
