The map below shows the percentage of land covered by tree canopy (based on data by the U.S. Geological Survey from 2010) together with a shaded relief representing elevation (also based on data by the USGS) in the regions Chubu, Kanto, and Tohoku of the Japanese island Honshu (the regions Kansai and Chugoku are shown on a separate map).
It is part of my larger map of the region of Japan and the Korean Peninsula.
