Umanomezara (lit."horse-eye" pattern plate) are thick and heavy stoneware serving plates fired in the Seto region after the late Edo period (early 19th century). They were mass-produced for rough everyday use. Ovals are painted with iron underglaze along the inner rim of the plates, from which the term "horse-eye" is said to derive. Although the origin of the name is not clear, these plates were already called by this name by the Meiji period.
