We developed an atmospheric emissions inventory of whole Japan; aimed to provide fundamental data for atmospheric transport modeling research. Target years of the inventory are 1995 and 1998, and target pollutants are NO<SUB>x</SUB>, SO<SUB>2</SUB>, CO, NMVOC, PM<SUB>10</SUB>, NH<SUB>3</SUB> and CO<SUB>2</SUB>. Emissions data are spatially divided to 10 km grid scale and timely divided to daytime and nighttime of each month. Total anthropogenic emissions of each pollutants in 1998 are 2.2 Tg NO<SUB>x</SUB>, 1.0 Tg SO<SUB>2</SUB>, 1.9 Tg NMVOC, 3.8 Tg CO, 0.18 Tg PM<SUB>10</SUB>, 0.5 Tg NH<SUB>3</SUB>, 1.1 Pg CO<SUB>2</SUB>. Furthermore, biogenic NMVOC emissions were estimated as 1.8 Tg. The spatial distributionof each pollutant commonly shows high emissions in the urban areas; characteristic distributions from agricultural sources in case of NH<SUB>3</SUB> and from forest sources in case of NMVOC are also shown. Furthermore, NH<SUB>3</SUB> and NMVOC emissions have a significant peak in summer season.
