About 60 climbing kilns formerly operated, most of which were constructed starting in the Meiji era. The chimneys became a landmark of the town, but many were closed and taken down after the Second World War as production methods modernised and burning of ovens was regulated by the authorities to protect the air quality. The Tōei Kiln (陶栄窯) is a climbing kiln ("nobori-gama") that was constructed in 887 and used until 1974. It is the largest climbing kiln existing in Japan. It was designated as an Important Tangible Cultural Property by the government in 1982. It has eight firing chambers running a 17° incline and ten chimneys of varying height.
