Comparing satellite maps from 2000 and 2020, the forest around Ichinoseki stayed about the same size, at about 17,600 hectares: new forest grew on about 309 hectares, and about 415 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 is the tree count in Ichinoseki?
Ichinoseki has an estimated 147,655 trees across the 12.57 km² measured — 47.0% tree cover, already past the 30% tree-cover target set for this area.
How many more trees does Ichinoseki need?
Ichinoseki has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Ichinoseki'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 Minamimachi; the tree count is an estimate derived from that cover.
