Net biome production (NBP) is considered as the most appropriate concept for analyz-ing long-term and large-scale changes of the carbon cycle induced by land use. We have esti-mated NBP potential of Japanese managed forests, based on their age structure, to be 16 Mt C/a. Fifty-nine percent of this sink is located in the warm-temperate broadleaf forest zone and the re-maining 39% is located in the cool-temperate broadleaf forest zone. This potential of NBP could be achieved under a long rotation period (70 a) and may serve as a target for sink enhancement ef-forts with the potential to uptake up to 4% of current fossil fuel emissions.
