(Click on the figure for enlargement)

Where do the bears in Tokyo live? The above figure maps the ranges of the radio-tracked bears (nine in total) around Lake Okutama. The territories are drawn on the basis of a computer algorithm (95% Convex Polygon), indicating the areas they are believed to use routinely. You may find it surprising how closely they live to human residential areas, their territories extending from the depth of the mountains to the mountain foot.D
