Himitu-bako is a name given to small box made by combining puzzle-mechanism with cabinetwork technique. These boxes first appeared in the Edo-era, when the principle of trick-mechanism was first developed. The technique was perfected in the middle of the Meiji era, and since then, continuous improvements have been made to complete the Himitu-bako to perfection as they are found today. To open the box, each box must be rotated, turned and moved a specific number of times(steps). Full of surprises and unique ideas, boxes such as these cannot be found anywhere else in the world.
