This is a pottery piece made in the southern part of China, commonly referred to as the "Han dynasty three colors" style. Its shape resembles that of a duck, and it is painted with yellow and green glazes, covering its body. The Han dynasty three colors were introduced to Japan as trading porcelain in the 16th century, and excavations have reported discoveries of such artifacts at Osaka Castle and other sites of Japanese feudal lords.
