Fujimino's air quality reflects the flat Saitama southern Iruma River plain adjacent to Tokyo, with vehicle traffic on surrounding roads and the manufacturing and residential character contributing local sources. The flat Kanto Plain allows reasonable dispersal, while the broader Tokyo metropolitan regional emissions elevate background and summer photochemical ozone is the primary warm-season concern and Fujimino generally maintains moderate Tokyo northwestern Saitama suburban readings throughout most of the year.

Frequently Asked Questions
Is air quality bad in Fujimino right now?
On 21 September 2026, overall air quality in Fujimino is fair. AQI is the main air quality indicator at 32.4/100. Pollution peaks around 12:00 PM (NO2: 32.4/100).
Will air quality be worse tomorrow in Fujimino?
On 22 September 2026, air quality conditions in Fujimino will be worse than today, with AQI forecast at moderate at 59.2/100. Pollution peaks around 6:00 PM (NO2: 59.2/100).
When is air pollution at its worst in Fujimino?
The biggest local contributors to pollution in Fujimino are road traffic, petrochemical and refining operations, along with textile and manufacturing operations, particularly once warm, sunny weather takes hold. Heat and sunlight combine with emissions to form ozone at ground level. This is far less of an issue outside the warmer months.
Are air quality levels in Fujimino 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.
