Between 2012 and 2025, VIIRS detected fire in 739 km² of Hokkaidō at least once. In an average year it detected fire in 96 km², ranking 3rd 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 2014, with 130 km² detected; the quietest was 2025, with 54 km². The 2021–2025 average is 24% lower 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.
August, September and October together hold 32% of the fire-days in the record. The single busiest day was 14 May 2016, with detections in 23 cells.
Ground that burns again
Of the 739 km² with at least one detection, 15% had detections in three or more different years.
| Years with a detection | km² | Share |
|---|---|---|
| 1 year | 534 | 72% |
| 2 years | 94 | 13% |
| 3 to 5 years | 73 | 10% |
| 6 to 10 years | 25 | 3.4% |
| 11 years or more | 14 | 1.9% |
The half-degree square with the most fire-days is centred at 42.25, 140.75 and holds 31% of the region'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.
