Making kanawatsugi requires great precision and craftsmanship. The boards must be carefully aligned and adjusted to each other. The connection is made using wooden wedges, which are driven into grooves in the boards.
Kanawatsugi is used in a variety of structures, including house frames, bridges, doors, windows and other furniture. It is one of the most reliable and durable compounds in Japanese woodworking.
