Comparing satellite maps from 2000 and 2020, the forest around Osaka grew from about 269 hectares to 290 hectares, a net gain of about 21 hectares (+7.8%). New forest grew on about 26 hectares, while 5 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.

New forest grew on about 26 hectares, while 5 hectares were lost.
What is the tree count in Osaka?
Osaka has an estimated 7,117 trees across the 10.55 km² of land measured — 2.7% tree cover, 27 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Osaka need?
Osaka needs roughly 71,957 more trees to close a 27-point shortfall against its 30% tree-cover target — about 1,583 t of extra CO₂ absorbed per year once grown.
How are Osaka'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-3 Nakanoshima; the tree count is an estimate derived from that cover.
