As the base for the lacquer, a variety of woods are used, each for a different kind of lacquer ware; for example, beech and horse chestnut are used for round lacquer ware such as wan(a dinner bowl) and hachi(a big bowl), and trees are used for angular lacquer ware such as jubako(tiered boxes).
However, it is getting more and more difficult to obtain the broadleaf wood necessary for the production of Kawatsura Sikki.
