Yaizu's air quality benefits from its exceptional Shizuoka Prefecture Suruga Bay coastal position, with consistent Pacific and Suruga Bay maritime breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the tuna fishing port — Yaizu being Japan's largest tuna port — and manufacturing corridor contribute local sources, while the outstanding coastal exposure and the Fuji and Southern Alps backdrop create dramatic topographic variation and Yaizu generally maintains good to moderate conditions for a major Japanese Pacific coastal fishing city throughout most of the year.

When is air pollution at its worst in Yaizu?
The biggest local contributors to pollution in Yaizu are vehicle traffic, manufacturing and food processing, and fishing fleet activity, particularly once the sea breeze weakens. Sea breezes typically keep conditions in check, except during still weather. This coastal advantage is less pronounced during still, high-pressure weather.
Are air quality levels in Yaizu 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.
