Kojima Shoten is an old, established workshop that has been making Kyo-chochin since the Edo period. The entire process is done in the jibari-shiki method, in which everything from the creation of the bamboo frame, the pasting of paper, to the pictorial decoration is done by hand. The product of a time-consuming, labor-intensive process, that Kyo-chochin is characterized by its sturdiness and the rich texture of its materials. As for durability, it can easily last 10 years of kept out of the rain.
using a square, the bones are cut to a predetermined length. The top side of the square has the measurements for the bones on the upper half of the chochin, and on the bottom side the measurements for the bones on the lower half. To improve overall appearance, the upper and lower halves are not symmetrical; rather, the lower half is somewhat smaller than the upper. Consequently, the size and number of bones above and below are different.
