Air quality today
The air quality in Kashiwara is currently classified as Good. The primary pollutant identified is PM2.5, with a measured concentration of 8.0 µg/m³ based on four valid observations reported through OpenAQ.
These measurements indicate that fine particulate levels are within the range associated with the Good category. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The dataset for Kashiwara includes measurements of nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX) and fine particulate matter (PM2.5). All four pollutants are represented, but the data comes from a single monitoring site located at 柏原市大字高井田８０９－１. In total there are four rows of observations, each corresponding to one of the measured species.
The most recent values were recorded on 2026‑02‑10 at 22:00 UTC, which falls within the “updated within three days” window, so the information is currently fresh. For NO the reported range is 0.0 ppm (minimum, median and maximum are identical), indicating a uniform reading across the available row. Both NO₂ and NOX show an identical value of 0.01 ppm with no variation – the 10th and 90th percentiles match the median, so the dataset does not capture any spread for these gases. PM2.5 is reported as 8.0 µg/m³, again with a single consistent figure across its row.
Because only one station contributes data, the coverage is limited to that specific neighbourhood; conditions elsewhere in Kashiwara may differ. The uniformity of the numbers (no observed minimum‑maximum range) suggests that the current snapshot does not reveal variability over time or space for any of the pollutants. Nonetheless, the timestamps confirm that the latest readings are recent, providing a timely but geographically narrow picture of air quality in the city.

Data notes
The current dataset for Kashiwara is based on four valid measurements and was refreshed recently, with the latest update recorded at 2026‑02‑10T22:00:00+00:00 (updated within 3 days). This snapshot reflects conditions at the time of sampling; however, air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
