The purpose of this study is to clarify the influence of the characteristics of the textile industry on the architectural characteristics of the saw roof factories. In this study, we conducted a field survey of the saw roof factories and the transition of the textile industry in the three regions of Bishu, Mikawa, and Chita in Aichi prefecture, which are representative textile production areas in Japan, and analyzed the relationship between the two. This study reveals that the saw roof factories have different architectural characteristics in terms of factory scale and construction methods due to the management system differences and the textile industry scale.
