A traditional wooden craft of Hakone.

Wooden crafts were already popular souvenirs for Hakone in the middle of Edo Era (1603-1868). In late Edo Era, an artisan introduced the techniques of Yosegi or mosaic, and applied it to the surface of his crafts. It was said to be the first Hakone Yosegi Zaiku. In 1984, Hakone Yosegi Zaiku was designated as a traditional craft by Minister of International Trade and Industry (present Economy, Trade and Industry).

For Hakone Yosegi Zaiku, woods are categorized by color and cut in fixed shapes and lengths. Utilizing their natural colors, motifs are made. Matching up motifs, elaborate geometric patterns are made in the form of base board of certain thickness. Then a plane is shot on the base board to produce patterned sheets with the thickness less than 0.2mm to decorate the surface of crafts. This is the classic type of Hakone Yosegi Zaiku. A new method of turning the base board itself to form pieces of work was introduced in the middle of the 20th century.
