| The carbon (C) stocks of dead wood, litter, and soil are the basic data for evaluating the C sink function in the forest sector in Japan. We estimated the C stocks of dead wood, litter, and soil at 0-30 cm in the forest sector in Japan and clarified the spatial distribution of those C stocks according to region units. Data were collected in 2438 survey plots in FY 2006-2010 by the National Forest Soil Carbon Inventory Project, which surveyed the C stocks of dead wood, litter, and soil at 0-30 cm throughout the forest sector in Japan. The C stock (mean ± sample standard deviation) of dead wood, litter, and soil at 0-30 cm was 0.42 ± 0.67, 0.49 ± 0.32, and 6.94 ± 3.25 kg m-2, respectively. The C stock of soil at 0-30 cm was slightly lower than previous study in Japan. The difference might be attributed to the difference of the sampling methodologies. The C stocks of the three pools were significantly different among regions. Although temperature influenced the tendency in the distribution of the C stocks among regions of dead wood and litter, the tendency was not unidirectional. On the other hand, the C stock of soil at 0-30 cm was higher in northern Japan and lower in southern Japan, although high C stock was observed in some regions in the volcanic region of southern Japan. Thus, we suggest that the soil C stock at 0-30 cm is regulated by macro scale factors such as temperature as well as by the distribution of volcanic ash soils.
