Kushiro's air quality benefits from its exceptional Pacific Ocean and Kushiro Marsh coastal position in eastern Hokkaido, with consistent Pacific and sub-Arctic maritime breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the fishing, pulp, and services corridor contribute local sources, while the outstanding Pacific coastal exposure and the Kushiro Wetland National Park's extraordinary natural setting generally maintain Kushiro among Hokkaido's cleaner coastal cities throughout most of the year.

When is air pollution at its worst in Kushiro?
In Kushiro, vehicle traffic together with port and shipping activity are the main local sources, with conditions worsening when the sea breeze weakens. Onshore breezes usually help clear the air, but pollution can build up when winds are light. This natural ventilation is one reason coastal areas often see better readings than inland cities.
Are air quality levels in Kushiro 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.
