Nerima's air quality reflects the northwestern Tokyo metropolitan residential corridor, with vehicle traffic on surrounding expressways and the dense urban residential and commercial character contributing elevated NOₓ. The flat Kanto Plain allows reasonable dispersal, while the broader Tokyo metropolitan regional emissions elevate background and summer photochemical ozone from the vast Kanto corridor is the primary warm-season concern and Nerima generally maintains moderate Tokyo northwestern residential corridor readings throughout most of the year.

Will air quality be worse tomorrow in Nerima?
On 17 July 2026, air quality conditions in Nerima will be similar to today, with SO2 forecast at fair at 39.1/100. Pollution peaks around 5:00 AM (NO2: 41.7/100).
When is air pollution at its worst in Nerima?
In Nerima, traffic emissions together with petrochemical and refining operations are the main local sources, with conditions worsening when summer heat and strong sunlight build up. Photochemical reactions in the heat push ozone levels higher. Readings are generally lower during the cooler, cloudier months.
Are air quality levels in Nerima 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.
