Fujisawa's air quality benefits from its exceptional Sagami Bay and Pacific Ocean coastal position in Kanagawa Prefecture, with consistent Pacific and Sagami Bay maritime breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the Enoshima tourism, manufacturing, and residential corridor contribute local sources, while the outstanding Pacific coastal exposure generally maintains Fujisawa among Kanagawa's more moderately ventilated coastal cities and summer photochemical ozone from the broader Kanto corridor is the primary warm-season concern.

When is air pollution at its worst in Fujisawa?
In Fujisawa, traffic on the surrounding roads, heavy industry such as steel, cement, or petrochemical processing, as well as textile and manufacturing operations are the main local sources, with conditions worsening when warm, sunny weather takes hold. Heat and sunlight combine with emissions to form ozone at ground level. Sea breezes typically keep conditions in check, except during still weather.
Are air quality levels in Fujisawa based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
