a Map showing the altitude [m] of northern and eastern Japan, and the distribution of regions with surface air temperatures that favor the maintenance of permafrost (the Environmentally Conditioned Permafrost regions) in Japan; b Hokkaido and c the Chubu. The numbers indicate (1) Daisetsu Mountains, (2) Hidaka Mountains, (3) Northern Japan Alps, (4) Mt. Fuji, (5) Mt. Shiretokodake, (6) Mt. Shari, (7) Southern Japan Alps, (8) Mt. Akandake, and (9) Mt. Yotei. The distribution of the environmentally conditioned permafrost region is based on probabilities estimated by nine bias-corrected climate scenarios
