Kamisu's air quality reflects the Ibaraki Prefecture Pacific Ocean and Kashima Nada coastal position adjacent to the Kashima Coastal Industrial Complex, with vehicle traffic on surrounding roads and the extraordinary steel, petrochemical, and chemical operations generating elevated industrial SO₂ and PM2.5. Consistent Pacific maritime breezes provide coastal ventilation, while the industrial complex's extraordinary scale makes Kamisu one of Japan's most distinctively heavy industrial Pacific coastal environments and the outstanding coastal exposure manages emissions on most wind days throughout the year.

Frequently Asked Questions

Is air quality bad in Kamisu right now?

On 10 August 2026, overall air quality in Kamisu is fair. AQI is the main air quality indicator at 21.5/100. Pollution peaks around 11:00 PM (O3: 21.5/100).

Will air quality be worse tomorrow in Kamisu?

On 11 August 2026, air quality conditions in Kamisu will be similar to today, with AQI forecast at fair at 26.9/100. Pollution peaks around 8:00 PM (O3: 26.9/100).

When is air pollution at its worst in Kamisu?

The biggest local contributors to pollution in Kamisu are road traffic and petrochemical and refining operations, particularly once dry, windy weather picks up. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Onshore breezes usually help clear the air, but pollution can build up when winds are light.

Are air quality levels in Kamisu 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.

Why doesn’t the forecast always reflect wildfire impacts?

Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.

During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
