Ouchi-nuri is centered in Yamaguchi City and appears across several forms rather than one fixed object. Local descriptions name bowls, trays, confectionery bowls, individual plates, stationery boxes, tiered boxes, flower vessels, chopstick boxes, tea saucers, banquet trays, and Ouchi dolls. The same lacquer family can therefore sit on a table, hold writing things, or stand as a small household figure.
The paired Ouchi doll gives the craft one of its most familiar shapes. It is associated with marital harmony, and local experience programs focus on drawing the face, making chopsticks, or applying lacquer and gold leaf to small accessories. These activities keep the material vocabulary visible: red ground, colored lacquer, metal leaf, and a hand steady enough for small curves.
