Air quality today
The air quality in Fujiyoshida is rated as Good today. The primary pollutant measured is PM2.5, with a reference concentration of 2.0 µg/m³ reported from five valid observations.
Data are shown via OpenAQ and reflect the current monitoring results for fine particulate matter. 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 Fujiyoshida contains five individual measurements taken at a single monitoring site located at 富士吉田市上吉田１丁目２－５. All five pollutants that the OpenAQ feed reports for this city are present: nitrogen monoxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). Each pollutant has exactly one recorded value, so the data set does not provide a range of observations across different times or locations within the city.
All five rows were last refreshed on 2026-02-10 22:00 UTC, which falls within the “updated within three days” freshness bucket. This means the information is relatively current, but because there is only one timestamp for each pollutant, the dataset cannot show any temporal variation. The measured values are tightly clustered: NO and SO₂ both read 0.0 ppm, while NO₂ and NOX each register a single reading of 0.048 ppm. PM2.5 shows a solitary concentration of 2.0 µg/m³. Because each pollutant has only one data point, the median, minimum and maximum are identical for every substance.
With just one monitoring location contributing all five rows, coverage across Fujiyoshida is limited to that specific address. Consequently, while the numbers give a snapshot of current air quality at that spot, they do not capture possible differences in pollutant levels elsewhere in the city or changes over time. Users should keep in mind that conditions can vary by neighborhood and hour, and the present dataset reflects only this single point-in-time measurement.

Data notes
The data shown reflects five valid measurements and is updated within 3 days, with the latest values recorded on 2026‑02‑10 at 22:00 UTC. This snapshot provides a current view of air quality in Fujiyoshida, but conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured by these figures.
