In Tsuruoka City, Yamagata Prefecture, Japan, Swidden is traditionally carried out in the forest land after clear-cutting. It is regarded as one of the efforts to promote reforestation. We evaluated the effect of reducing WB production cost itself and biomass power generation cost, and the impact of swidden on the revitalization of this area. It was clarified that the improvement of work efficiency and the sales profit of swidden can reduce the cost by about 7% in terms of WB production and about 5％ in terms of biomass power generation. It was suggested that swidden has a certain effect on both increasing the use of WB and achieving economic independence in the forestry.
