Yosegi-zaiku is a Japanese technique of parquetry which dates from the Edo period. Yosegi-zaiku parquetry is made differently than Western parquetry. Sticks of woods of different colours are glued together to form a block which section is then cut in very thin slices forming a design. Yosegi-zaiku parquetry is a speciality of Hakone region.
One of the most famous item decorated with this technique is a puzzle box ('himitsu-bako') which can only be opened by using a certain number of secret movements.
