Oya stone is a precious finite Japanese stone material that can only be mined in the Oya district of Utsunomiya City, Tochigi Prefecture in Japan. Because it is light and soft, it is easy to process and has excellent fire resistance, it has been widely used in Japanese houses and KURA such as Japanese-style warehouses. In 1922, Oya Stone was also used in Imperial Hotel Tokyo, which was famous for the design of American architect Frank Lloyd Wright, and the name of Oya Stone and its recognition as a building material spread nationwide.
