About Tanihata’s Kumiko

Kumiko is a delicate and sophisticated technique of assembling wooden pieces without the use of nails. Thinly slit wooden pieces are grooved, punched and mortised, and then fitted individually using a plane, saw, chisel and other tools to make fine adjustments.
The technique was developed in Japan in the Asuka Era (600-700 AD), and has since been refined and passed down through generations of craftsmen who are passionate about the tradition of Kumiko.
