Mukimono

Mukimono (剥き物) is the traditional Japanese art of decorative garnishing. Examples of this include carving traditional images (flowers, cranes, turtles and dragons) into skins of fruit and vegetables, as well as carving vegetables (such as daikon, carrot, eggplant) into attractive shapes such as flowers, twists, and fan shapes. These are commonly served as a garnish on the same plate as the meal, or on a small side plate.

Cutting food in Mukimono style is a way to create a sense of the four seasons. The taste of the four seasons improves the appearance of the cuisine and plays a major role in improving the flavor.
