SUMI is a wooden geometric box that was made by redesigning the “Yusan-bako”, a traditional picnic/sweets box indigenous to Tokushima prefecture, one of the islands located in western Japan. “Yusan-bako” is a three-tiered food box with a two-tiered outer box intended for portable use. The traditional “Yusan-bako” has two holes on both sides of the outer box, and therefore requires you to use both hands to open. However, Sumi allows the user to pull the inner boxes by one hand only. This was made possible due to the change in the position of these holes to the edge of the outer box. This change allows a better design of the handle and lid.
Japan is facing a loss of outstanding works by traditional artisans, due to the exponential growth of the production of consumer goods. To uphold both the artisans’ traditional craftworks and local industry, NOSIGNER collaborated with the woodwork artisans in Tokushima to produce Sumi. We hope this contributes to the betterment of the situation faced by these artisans.
