Kakegawa's air quality reflects the Shizuoka Prefecture Pacific coastal plain position adjacent to the Hamana Lake corridor, with vehicle traffic on surrounding roads and the tea, manufacturing, and food processing corridor contributing local sources. Consistent Pacific and Enshunada Bay maritime breezes provide coastal ventilation, while summer photochemical ozone from the broader Shizuoka corridor is the primary warm-season concern and Kakegawa generally maintains moderate to good Japanese Pacific coastal plain readings throughout most of the year.

When is air pollution at its worst in Kakegawa?
Air quality in Kakegawa tends to be worse when traffic emissions, heavy industry such as steel, cement, or petrochemical processing, together with textile and manufacturing operations build up and warm, sunny weather takes hold. Strong sunlight reacting with local emissions drives up ground-level ozone. Onshore breezes usually help clear the air, but pollution can build up when winds are light.
Are air quality levels in Kakegawa 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.
