Mokjogakjang refers to the skill of wood Sculpture or to an artisan with such a skill. Among the woods commonly used for this skill is paulownia, pine, fir, gingko, zelkova and pagoda wood. It is presumed that wood Sculpture started on the Korean Peninsula, mostly on temples and Buddha images, with the introduction of Buddhism during the Three Kingdoms Period (circa 57 BC – 668 AD). Many of these wood Sculpture works were destroyed during the frequent foreign invasions suffered by Korea.

As for the process of wood Sculpture production, first a sketch is made on well-dried wood and the remaining parts are cut off. When a rough form is made, the inside is gouged out to prevent cracks or to make a space for inserting ancillary objects according to the custom. Lacquer is applied to the completed object.
