Comparing satellite maps from 2000 and 2020, the forest around Kagoshima stayed about the same size, at about 10,900 hectares: new forest grew on about 105 hectares, and about 180 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.

Kagoshima has an estimated 23,882 trees across the 11.38 km² of land measured — 8.4% tree cover, 22 percentage points short of the 30% tree-cover target set for this area.
How many more trees does Kagoshima need?
Kagoshima needs roughly 61,412 more trees to close a 22-point shortfall against its 30% tree-cover target — about 1,351 t of extra CO₂ absorbed per year once grown.
How are Kagoshima'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-14 Kamoike; the tree count is an estimate derived from that cover.
