Sapporo's air quality is generally good by Japanese standards, with the Ishikari Bay coastal position and the surrounding Hokkaido mountains providing reliable ventilation across Japan's northernmost major city. Vehicle traffic on surrounding expressways and the tourism, food processing, and services corridor contribute modest local sources, while the excellent Sea of Japan and Pacific maritime ventilation and the clean Hokkaido boreal setting generally maintain Sapporo among Japan's cleaner major metropolitan cities throughout most of the year.
