Onta ware was established about 300 years ago in this region. In line with their method of creation passed down over the years, the potters of Onta still utilize mortar made with the local valley stream and firewood to ignite their ascending kilns built on a slope.
Onta Japanese pottery was designated as an Important Cultural Property under the Law for the Protection of Cultural Properties in 1970.
