One of the reasons for Yamanaka's competitiveness over other lacquerware production sites is its wide range of kashokubiki techniques.

Kashokubiki is a traditional technique of carving decorative patterns on the surface of a material using an edge tool such as a plane. It is said that there are forty to fifty types of kashokubiki. Basic types include parallel grooves called suji and spiral patterns. With the original techniques of individual woodturners and delicate breaths (esoterics), a broad range of designs have been developed for different wood types and shapes. Kashokubiki adds beauty to the lacquerware, and also has the practical function of helping a person's grasp.
