We estimated the economic ripple impact of utilizing locally supplied wood products from Saitama prefecture on a public building, Sugito Kindergarten-Nursery School. We used the Saitama prefecture Input-Output Table for estimations in two scenarios: (1) A basic scenario conforming to the actual distribution route including the outflow of prefectural roundwood to other prefectural sawmills and the inflow from other prefectural sawmills to Saitama; (2) A comparative scenario assuming that all production and distribution of roundwood and lumber are completed within Saitama. The results of estimation produced a total induced production value and induced production coefficient of 35.101 million yen and 1.09, respectively, in the basic scenario, and 44.9 million yen and 1.39, respectively, in the comparative scenario, indicating a greater economic ripple impact with the comparative scenario. It shows that promoting the consumption of local wood products on public buildings could be effective both for vitalizing the forestry and wood processing industry, and for the prefectural economy. Furthermore, some sawmills in Saitama will acquire JAS-certified for manufacturing lumbers possessing rectangle cross section for beam, this effort may help to increase the consumption of local structural lumbers on public buildings. The economic ripple impact of utilizing local wood products on public buildings will increase in the future.
