Local production for local consumption of renewable energy is focused on as a policy of regional activation in rural area while it is considered a social problem that farmlands are desolate there. This report mentioned the cost during pilot production of willow, which is called one of the neo-generation biomass, in two small-scale idle farmlands (under one hectare) aiming for the farmlands preservation. From the results, we confirmed that the production by either outsourcing or land owner in this report were into the red (about -55,000 to -27,000 JPY/10 a) and that the yield of willow was about 1.0 dry-t/10a in one season although higher planting density reduce the yield per a tree regardless of the management frequency.
