Comparing satellite maps from 2000 and 2020, the forest around Okinawa stayed about the same size, at about 5,090 hectares: new forest grew on about 171 hectares, and about 71 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.

What has the air quality in Okinawa been like this week?
Over the last 7 days, the CAMS air-quality model put Okinawa's daily AQI at 47 on average, from 27 on Nov 11 to an hourly peak of 66 on Nov 7. No day averaged above 100, the level where the air turns unhealthy for sensitive groups.
How much forest has the area around Okinawa lost since 2001?
Since 2001, the area within 10 km of Okinawa has lost about 415 hectares of forest (about 580 football pitches): 12% of the forest it had in 2000. Most of it (84%) was deforestation, forest cleared for good, mainly for towns and roads. Comparing satellite maps from 2000 and 2020, the forest around Okinawa stayed about the same size, at about 5,090 hectares: new forest grew on about 171 hectares, and about 71 hectares were lost.
What is the tree count in Okinawa?
Okinawa has an estimated 71,314 trees across the 12.57 km² measured — 22.7% tree cover, 7 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Okinawa need?
Okinawa needs roughly 22,934 more trees to close a 7-point shortfall against its 30% tree-cover target — about 504.5 t of extra CO₂ absorbed per year once grown.
How are Okinawa'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 1 Chome-9 Goya; the tree count is an estimate derived from that cover.
