Assessment validates anthropogenic emission inventories for PM2.5, SO2, and NOx in Japan, highlighting the need for precise inventory selection.

HTAP provided the most balanced SO2 and CO fields, with regional mean biases mostly within ±25%.
CAMS-GLOB-ANT systematically under-estimated PM2.5 and CO while over-estimating SO2, highlighting needed adjustments.
ECLIPSE reproduced NOx spatial gradients best despite a negative overall bias, indicating variability in performance among inventories.
Emissions uncertainty dominated air quality error, suggesting the necessity for multi-inventory approaches to improve assessments.

Tatsumi et al. (2025) studied this question.
