A species of Old World warbler in the family Phylloscopidae. It inhabits temperate forests and is found in Sakhalin, the Kuril Islands, and Japan, wintering in the Amami and Okinawa islands and Indochina.

Features a long white supercilium and broad, dark brown eye-stripes. The crown, upper parts, and bill are dark brown. Cheeks are greenish-brown with mottled ear-coverts. The bill has a pink base extending to the lower mandible, and legs are pale pinkish-brown.
