'Ohya-ishi' stone is mainly used for building materials, as it is easy to cut and is resistant to fire.

Ohya-ishi stone is formed from volcanic ashes settled on the bottom of the sea. It is reserved in Ohya town, Tochigi Prefecture, and 120 quarries were running in the golden age in the 1960s. However the number of them has dwindled now to one-tenth of that time. As shown in the first picture, open-cut mining is found there though, underground mining is the mainstream now to get the better quality of stones. The second picture shows the interior of the mine which already shut down the operation. These ruins are opened to the public as a museum named 'Ohya-shiryo-kan'. As the temperature deep inside the ruins is stable all the year, from 5 to10 degrees Celsius, it was used as a warehouse for rice, other cereals and fermented foods. In recent years, it has become a popular place for a filming location and event site.
