Deforestation · 2001–2025
Which country has lost more forest, Japan or Russia?
Russia has lost more: about 91.7 million ha of forest from 2001 to 2025, against 1.02 million ha in Japan, or 90 times as much. 1 million ha of Russia's was cleared for good, for farms, mines or towns; the rest burned, was logged or can grow back.
The whole country, from the yearly satellite maps of forest loss: unlike the city averages above, this counts every forest, not just the land around cities.
Worst year: 2016, with 54,800 ha lost.
Worst year: 2021, with 6.49 million ha lost.

Reading these numbers
What a country average is, and is not
It is a mean of cities
Not a national statistic. Each figure is the average across the cities Airleaf has measured: 207 in Japan and 168 in Russia, each read over the same 2 km radius, on the US EPA index. Rural land and unmeasured towns are not in it.
Coverage shapes the number
A country measured mostly in its capital reads differently from one measured across dozens of towns. Japan rests on 207 cities against 168, so its average is the steadier of the two. Forest figures come from the University of Maryland's Global Forest Change maps.
Frequently asked
Japan vs Russia: your questions answered
Is Russia cleaner than Japan?
On air quality, yes, right now: Russia's cities average AQI 32 against 47 on the US EPA index. These are live readings averaged across cities, so the gap moves with the weather.
Which country has lost more forest, Japan or Russia?
Russia has lost more: about 91.7 million ha of forest from 2001 to 2025, against 1.02 million ha in Japan, or 90 times as much. 1 million ha of Russia's was cleared for good, for farms, mines or towns; the rest burned, was logged or can grow back.
Which country has more tree cover, Japan or Russia?
Russia does: its measured cities average 34.1% tree cover against 16.4%, a gap of 17.7 percentage points.
How many cities are the Japan and Russia figures based on?
207 measured cities in Japan and 168 in Russia. Every one was read the same way, so the two averages are directly comparable, but a country with more measured cities has the more settled figure.
Does this cover the whole of Japan and Russia?
The air and tree figures are not: they are the cities Airleaf has measured, each over the same 2 km radius, so treat them as a comparison of urban air and urban tree cover. The forest figures are: they count every forest in the country.
