Kashiwazaki's air quality reflects the Niigata Prefecture Sea of Japan coastal position adjacent to the Kashiwazaki-Kariwa nuclear power station — the world's largest nuclear plant — with vehicle traffic on surrounding roads and the nuclear operations' essentially zero combustion emissions and manufacturing corridor contributing local sources. Consistent Sea of Japan maritime breezes provide coastal ventilation, while the nuclear plant's zero direct combustion character and the outstanding Sea of Japan coastal exposure generally maintain Kashiwazaki among Japan's more moderately ventilated coastal industrial cities throughout most of the year.

Frequently Asked Questions
Is air quality bad in Kashiwazaki right now?
On 16 July 2026, overall air quality in Kashiwazaki is fair. NO2 is the main pollutant at 21.8/100. Pollution peaks around 12:00 PM (O3: 54.8/100).
Will air quality be worse tomorrow in Kashiwazaki?
On 17 July 2026, air quality conditions in Kashiwazaki will be worse than today, with AQI forecast at poor at 63.8/100. Pollution peaks around 12:00 PM (O3: 63.8/100).
When is air pollution at its worst in Kashiwazaki?
In Kashiwazaki, vehicle traffic, energy sector operations, together with light manufacturing are the main local sources, with conditions worsening when dry, windy weather picks up. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Maritime airflow normally ventilates the area well, though calmer spells let levels rise.
Are air quality levels in Kashiwazaki 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.
