In this paper, the food and energy self-sufficiency potential of Furano city, a region in central Hokkaido, Japan, was analyzed as a case study. First of all, Input-Output data was compiled for the main compartments of agriculture, dairy products, forestry, and citizenry in Furano city. Compartments were paddy rice, wheat, pasture, dent corn, onion, sweet corn, carrot, dairy cows, willow, forest, and citizenry. Secondly, supply and consumption per unit of land, per head of cattle, per capita related to food, energy, feed, nitrogen fertilizer were listed. Finally, by utilizing the specific figures, we analyzed the optimum land use model for energy self-sufficiency in Furano city using a linear programming analysis. As a result, we derived that the utilization of agricultural, livestock, and forestry biomass as energy results in an energy self-sufficiency potential of 20-48% influenced by nitrogen self-sufficiency.
