AB: This paper presents results of regional application of the CENTURY ecosystem model to Japanese forests. Global and regional evaluation of organic carbon stored in forest soil and greenhouse gases emissions from forest soils are important (e.g., the Kyoto protocol). Our goal is to develop a biogeochemical model that can simulate carbon dynamics in Japanese forests at both site and regional scales. We applied the CENTURY model to Japanese forest at 1 km × 1 km resolution (about 240000 grids) and compared the outputs with data of several datasets and reviewed results (net primary production, soil organic carbon, surface litter, soil respiration). This paper will present an overview of our modeling of organic carbon stored in Japanese forest soils and some preliminary results relating to carbon dynamics. Also, we will introduce an ongoing project of forest soil inventory in Japan, in which 3200 plots all over Japan will be surveyed.
