This study extracted production forests and estimated the annual available amounts of forest biomass resources under profitable forest management in Tochigi prefecture. Production forests were extracted as sub-compartments where expected revenues surpassed all costs—from planting to final harvesting—for a 55-year rotation. Then, annual available amounts of forest biomass resources were estimated on the basis of annual supply potentials from production forests. Annual supply potentials from precommercial, commercial thinning and final felling operations were 80,235 tons, 196,265 tons, and 216,982 tons, respectively. Annual available amounts were estimated at 29,920 tons, 72,639 tons, and 80,871 tons. When considering the profits to the forest owners, those were 8,594 tons, 20,279 tons, and 23,520 tons. The available amounts for Nakagawa and Mibu woody biomass power generation plants were 37,598 tons and 14,795 tons, which were 107% and 49% of annual demands for these plants, 35,000 and 30,000 tons, respectively.
