This is a vintage Japanese cake mold, called Kashigata which are hand carved from Yama Sakura wood (wild cherry wood) and comes in various shapes from the Early Showa (1920's-1940's).
Wild cheery is diffuse−porous wood so it does not have strong wooden grains and easy to carve,also water resistant which is ideal to use to make Japanese sweets.
The wood is dried for 5 years to prevent cracking. Mixtures of sugar, soy beans and soy flour are pressed into it and allowed to dry. The sweets, called kashi, were sold in confectionery stores and made for special occasions. The molds are crafted by only a few craftsman these days and are an interesting and beautiful piece of old Japan. They are quite collectible and are one-of-a-kind works of art speically this Kashigata shape with Daruma.
