The study historically identifies how Oya-stone quarrying has been affecting the local use of Oya-stone by taking residential areas in Utsunomiya City as case study sites. Topographical maps and historical literatures were examined while interviews and field observations were conducted to identify historical changes of the industry and the use of Oya-stone. The study identifies that stone walls remaining in old districts are mainly made of Oya-stone with a rough texture quarried by hand, while relatively low quality rough-textured stones quarried by machines are mainly used for foundations in new town districts. These findings illustrate that the buildings and infrastructures of Oya-stone has been characterized by the way how the stones were quarried and used. It is therefore suggested that measures to conserve local buildings and infrastructures should reflect how local materials were used in response to the industries.
