In this study, we focused on the large-scale wooden public buildings in Shimane Prefecture, and researched on wood procurement and production system. As a result, the following findings were revealed. 1) For wood preparation, local governments provide the preparation period by publishing the information of building. 2) For the preparation of drawings and construction suppliers, production systems are different depending on the size and the person in charge of local government. 3) For corresponding to the demand of locally produced material, regional organizations must increase the stock of wood, and it is necessary that various timber factories work together.
