It is found in Bangladesh, Cambodia, China, India, Indonesia, Japan, North Korea, South Korea, Laos, Malaysia, Myanmar, Russia, Singapore, Thailand, and Vietnam. Its natural habitats are boreal forests and temperate forests.Eastern Crowned Warbler breeds in south-eastern Transbaikalia, Lower Amur Basin, south-eastern Manchuria, Ussuriland, Korea, and Japan. In Japan, it commonly breeds in the four main islands (Hokkaido, Honshu, Shikoku, and Kyushu) and on Sado, but recently seems to be on the decline. Its breeding area is in the lowest altitude among the basic Japanese Phylloscopus (Arctic, Sakhalin Leaf, and Eastern Crowned Warblers). The peak of spring migration is in mid-May in Honshu. And the peak of autumn migration is in August, earlier than Arctic Warbler. They are almost not seen at all in October in Japan.
