Kan'onjichō's air quality benefits from its exceptional Kagawa Prefecture Seto Inland Sea and Hiuchi Nada coastal position, with consistent Seto Inland Sea maritime breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the manufacturing, fishing, and agricultural corridor contribute local sources, while the outstanding coastal exposure generally maintains Kan'onji among Kagawa Prefecture's more moderately ventilated coastal cities throughout most of the year.

When is air pollution at its worst in Kan’onjichō?
Air quality in Kan’onjichō tends to be worse when road traffic, manufacturing activity, as well as agricultural activity build up and maritime winds die down. Onshore breezes usually help clear the air, but pollution can build up when winds are light. Areas further inland without this ventilation tend to fare worse.
Are air quality levels in Kan’onjichō 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.
