Shibuya-ku's air quality reflects one of Tokyo's most intensely commercial and entertainment districts alongside Shinjuku, with vehicle traffic on surrounding expressways and the extraordinary concentration of Shibuya Scramble Crossing pedestrian and vehicle traffic generating sustained NO₂. The enclosed urban canyon geometry concentrates emissions, while the broader Tokyo metropolitan regional background elevates all readings and summer photochemical ozone from the vast Kanto corridor is the primary warm-season concern throughout the year.

When is air pollution at its worst in Shibuya-ku?
Pollution in Shibuya-ku typically rises when road traffic along with petrochemical and refining operations combine, especially once hot, still weather settles in. Photochemical reactions in the heat push ozone levels higher. This is far less of an issue outside the warmer months.
Are air quality levels in Shibuya-ku 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.
