Air quality today

The air quality in Amagasaki is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 20.0 µg/m³ based on fifteen valid observations from OpenAQ data.

These measurements indicate that particulate matter levels are present at the reference value for PM2.5, while no PM10 reference is provided. This assessment reflects the latest available data without speculation about causes or future conditions. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Amagasaki data set contains measurements for six pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). These observations come from 18 individual rows recorded at four monitoring stations across the city, giving a modest spatial picture of air quality.

All six pollutants have recent readings, with the newest timestamp for each being 2026‑02‑10 22:00 UTC, which falls within the “updated within three days” window. CO values range from 0.2 ppm to a maximum of 0.4 ppm, with a median of 0.35 ppm; the highest observed level (0.4 ppm) was recorded at the 南塚口町７の１７ site. PM2.5 concentrations sit between 14 µg/m³ and 20 µg/m³, centering around a median of 14.5 µg/m³, again with the lowest reading (14 µg/m³) coming from the same 南塚口町７の１７ location. NO shows a very low spread, from essentially zero up to 0.014 ppm (median 0.001 ppm), while NO₂ is recorded at a single value of 0.022 ppm across its three rows. NOX values vary more widely, from 0.001 ppm to 0.036 ppm (median 0.023 ppm). Sulfur dioxide was only measured at one station (東難波町4丁目9‑12) and all four rows report a value of 0.0 ppm.

The coverage is uneven: CO, PM2.5, NO, NO₂ and NOX each have three to four reporting stations, but SO₂ relies on a single location, limiting insight into city‑wide sulfur dioxide levels. While the data are fresh, the relatively small number of rows—especially for pollutants with only one or two stations—means that conditions can differ across neighborhoods and times not captured by this snapshot.

Data notes

The data shown reflects 15 valid measurements and is Updated within 3 days, with the most recent reading recorded on 2026‑02‑10 at 22:00 UTC. This snapshot provides a current view of Amagasaki’s air quality, but conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in this summary.
