Generally speaking about Japanese chests in the Middle Ages, Chinese style chest used for keeping treasures of shrines and temples have survived in their store rooms. But the pictures of many chests chracterzed by "vertical lines" and "horizontal lines" on the side of the chest are found in the Middle Age scrolls. They seem to have been destroyed in the Edo Era. So there are no longer any memories of its construction, scale and how to make it. This paper makes clear the mystrey of "vertical lines" and "horizontal lines" by re-examination of the scrolls, old tray served for meal and woodwork tools at the time. That is, they are given by splitting thine boards side by side. The result of these investigations, I restored the long chest referred to the middle 12th century document which mentioned the parts of chests. It is a very curious long and light chest made of split needle-leaf tree, without the use of saw and planner. Fig. 10 and 11 show parts and construction of the chest.
