Fire history, 2012–2025
Detected · VIIRS S-NPP 375 m · 0.01° cells (~1.1 km) · complete years 2012–2025 · built 2026-09-21
Between 2012 and 2025, VIIRS detected fire in 11,480 km² of Japan at least once. In an average year it detected fire in 1,660 km², ranking 108th of 200 countries.
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 2025, with 1,890 km² detected; the quietest was 2012, with 1,270 km². The 2021–2025 average is 20% higher than 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.
March, April and May together hold 29% of the fire-days in the record. The single busiest day was 11 March 2018, with detections in 262 cells.
Ground that burns again
Of the 11,480 km² with at least one detection, 18% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 7,630 | 66% |
| 2 years | 1,760 | 15% |
| 3 to 5 years | 1,370 | 12% |
| 6 to 10 years | 441 | 3.8% |
| 11 years or more | 285 | 2.5% |
The half-degree square with the most fire-days is centred at 35.25, 136.75 and holds 9.2% of the country's fire-days.

- 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.
