Akishima's air quality reflects the western Tokyo metropolitan Tama River valley position adjacent to Yokota Air Base's extended flight paths, with vehicle traffic on surrounding roads and the US Air Force aviation operations and manufacturing character contributing elevated NOₓ alongside primary vehicle sources. The flat Kanto Plain allows reasonable dispersal, while the aviation emissions represent the most distinctive local source and summer photochemical ozone is the primary warm-season concern throughout the year.

Frequently Asked Questions
Is air quality bad in Akishima right now?
On 16 July 2026, overall air quality in Akishima is poor. AQI is the main air quality indicator at 75.4/100. Pollution peaks around 1:00 PM (O3: 75.4/100).
Will air quality be worse tomorrow in Akishima?
On 17 July 2026, air quality conditions in Akishima will be better than today, with PM1 forecast at fair at 32.8/100. Pollution peaks around 12:00 PM (O3: 45.8/100).
When is air pollution at its worst in Akishima?
Air quality in Akishima tends to be worse when vehicle traffic, aviation activity from the nearby airport, and steel, cement, and chemical production build up and summer heat and strong sunlight build up. Strong sunlight reacting with local emissions drives up ground-level ozone. Cooler temperatures for the rest of the year keep this in check.
Are air quality levels in Akishima 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.
