Most polluted cities in Kyoto, Japan
14 measured cities, last 30 days; 0 above the WHO 24-hour guideline. Worst: Yawata at 6.7 µg/m³, #1,459 in the world.
About 0 people in these 3 cities breathed unhealthy air on an average day over the last 30 days.
Ranked by people: each city's population times its share of unhealthy days, those with a daily mean over 35.4 µg/m³ (US AQI 101+). That is how many people living there breathed unhealthy air on an average day. Only cities measured at 2 or more places at least 3 km apart are ranked: one monitor shouldn't speak for a whole city. Population is the city itself, not its wider metro area.
Cities coloured by their PM2.5 over the last 24 hours. Fires, smoke and ash: Oct 5, the newest UTC day mapped.
The US EPA's Air Quality Index for PM2.5 (2024 breakpoints). Show values as: µg/m³ · US AQI · India AQI · China AQI · European AQI · UK DAQI · Canada AQHI+. About the scales
Estimated: cities without a monitor
Kyoto cities we can't measure, with model estimates for the last 7 days. Listed by population, not ranked: estimates aren't precise enough to rank. Model estimates from the Copernicus Atmosphere Monitoring Service (CAMS), adjusted to measured cities nearby where there are any. Adjusted, a single day lands within ×1.5 of what a monitor would read about two times in three; unadjusted, it can be off by half or double. Treat them as a guide, not a measurement.
| City | 7-day estimate |
|---|---|
| Kamigyō-ku | ≈ 4 µg/m³ |
| Kyōtanabe | ≈ 7 µg/m³ |
| Tanabe | ≈ 7 µg/m³ |
| Mukō | ≈ 7 µg/m³ |
| Arashiyama | ≈ 4 µg/m³ |
| Yotsutsuji | ≈ 6 µg/m³ |
| Oyamazaki | ≈ 7 µg/m³ |
| Sayama | ≈ 8 µg/m³ |
