This century old Japanese decorative woodworking technique is nowadays only mastered by very few people in Japan. It requires many years of learning and painstaking accuracy to construct. The length, width and angle of each and every piece of wood has to be perfect, otherwise the whole construction would collapse since basically there are no screws, nails, or glue used to make these beautiful panels. They can be made in many different patterns and natural wood colors depending the wishes of the customers. The size of the panels is optional.
