Clean-air score
78/100
Solid air-quality score for a megacity, with health benchmarks still relevant.
Primary pollutant watch
PM2.5 and ozone
Dense urban activity keeps fine particles and ozone in the model.
Exposure modifier
Heat
Heat can amplify health risk and should be read alongside pollutant levels.
Tokyo air quality data table
This HTML table mirrors the visible score cards so important comparison data is never trapped in a browser-only chart.
| Metric | Value | Context |
|---|---|---|
| Clean-air score | 78/100 | Strong for scale, but health-guideline pressure remains. |
| Primary pollutant watch | PM2.5 and ozone | Important for long-term exposure and hot-season risk. |
| Exposure modifier | Heat | The model assumes strong urban monitoring context. |
