Between 2012 and 2025, VIIRS detected fire in 326 km² of Saitama Prefecture at least once. In an average year it detected fire in 46 km², ranking 13th of 47 regions of Japan.
Year by year
Detected area per year, km². Area of 0.01° cells with at least one detection in the year.
The busiest year was 2015, with 52 km² detected; the quietest was 2012, with 37 km². The 2021–2025 average is within 5% of the 2012–2016 average.
Through the year
Share of all fire-days 2012–2025 by month. A fire-day is one cell with a detection on one day.
October, November and December together hold 29% of the fire-days in the record. The single busiest day was 3 June 2013, with detections in 7 cells.
Ground that burns again
Of the 326 km² with at least one detection, 16% had detections in three or more different years.
| Years with a detection | km² | Share |

- How these figures are madeDetected area, cells, and the single-satellite record.
Detected area counts every 0.01° cell with at least one VIIRS detection, so a small fire counts as a whole cell and a fire missed by cloud or between passes is absent. Borders: Natural Earth 1:10m. 2012 begins on 20 January.
