Japanese bioenergy production system is strongly connected to the use of biomass from the country’s extensive forest resources and forest industry residues. Kiso town is promoting the use of woody biomass as a source of heat. However, if the younger generation is not aware of this project or biomass itself, there may be a shortage of future personnel in the biomass industry. Therefore, the education of woody biomass for the younger generation in Kiso Town might help regional revitalization. This study explores primary school students’ perceptions of biomass energy from forests with several factors.
