The kiln ruins are located in a valley southwest of Ashigaike in the central part of the Atsumi Peninsula. Until the discovery of this site 1950s, it was not known that pottery had been made on the Atsumi Peninsula. With the archaeological excavation of this large kiln site by the Tahara Town Board of Education in 1964, it became clear that a type of black pottery of unknown origin which had been discovered in many locations in the Tōkai region originated from this location. A total of eight kiln traces were discovered. Pottery produced at the Ōarako site was used for everyday items, such as large storage containers, tea bowls and funerary urns.
