Deforestation · 2001–2025
How much forest has Fukushima lost?
Since 2001, the area within 10 km of Fukushima has lost about 660 hectares of forest (about 920 football pitches): 5.3% of the forest it had in 2000. Most of it was lost to logging, so much of it can grow back. About 166 hectares (25%) was deforestation: forest cleared for good for farms, mines or towns.

Comparing satellite maps from 2000 and 2020, the forest around Fukushima stayed about the same size, at about 12,500 hectares: new forest grew on about 176 hectares, and about 249 hectares were lost.
These 2000 and 2020 maps, from the University of Maryland, count any land with trees taller than 5 m as forest, including plantations and orchards. Forest that was cut or burned and had grown back by 2020 counts in both years, so the loss here is smaller than the yearly figures.
These figures cover everything within 10 km of the city center, a wider area than the report above, because forest is usually lost at a city's edges.

Frequently asked
Questions about Fukushima
What is the air quality (AQI) in Fukushima right now?
The latest reading for Fukushima shows an AQI of 6 (Good), observed Nov 11, 11:00 local time via Open-Meteo / CAMS, corrected with 4 ground-station cities within 225 km, US EPA index. The main pollutant is PM2.5. Air quality is satisfactory for everyone.
Is it safe to exercise outside in Fukushima today?
At AQI 6 (Good): a good day to be active outside. Windows: open them to air the house. Masks: not needed. The reading changes through the day, so check again before a long run or ride.
What has the air quality in Fukushima been like this week?
Over the last 7 days, the CAMS air-quality model put Fukushima's daily AQI at 24 on average, from 7 on Nov 7 to an hourly peak of 59 on Nov 5. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
How much forest has the area around Fukushima lost since 2001?
Since 2001, the area within 10 km of Fukushima has lost about 660 hectares of forest (about 920 football pitches): 5.3% of the forest it had in 2000. Most of it was lost to logging, so much of it can grow back. About 166 hectares (25%) was deforestation: forest cleared for good for farms, mines or towns. Comparing satellite maps from 2000 and 2020, the forest around Fukushima stayed about the same size, at about 12,500 hectares: new forest grew on about 176 hectares, and about 249 hectares were lost.
What is the tree count in Fukushima?
Fukushima has an estimated 45,519 trees across the 12.31 km² of land measured — 14.8% tree cover, 15 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Fukushima need?
Fukushima needs roughly 46,749 more trees to close a 15-point shortfall against its 30% tree-cover target — about 1,028 t of extra CO₂ absorbed per year once grown.
How are Fukushima's air quality and tree cover measured?
Air quality comes from ground monitoring stations via OpenAQ where one reports nearby, and otherwise, as here, from the Open-Meteo / CAMS model, which may differ from street-level monitors. Tree cover is measured from Sentinel-2 L2A (ESA Copernicus) via Earth Search satellite imagery at 10 m detail across a 2 km radius around 2 Sugitsumacho; the tree count is an estimate derived from that cover.
