This large, heavily patterned thrush is similar in appearance to the scaly thrush, to which was considered a subspecies. It has warm olive-brown to buff upperparts and whitish underparts with heavy black scaling. It has twelve tail feathers. The scaly thrush is smaller and has fourteen tail feathers. It has a cheerful song similar to the Siberian thrush. Among thrushes, only the blue whistling thrush typically attains a larger size. The Amami thrush ranges in length from 29 to 31 cm (11 to 12 in) and weighs approximately 172 g (6.1 oz). Among standard measurements, the wing chord is 16.4 to 17.3 cm (6.5 to 6.8 in), the bill is 3.1 to 3.3 cm (1.2 to 1.3 in) and the tarsus is 4.1 to 4.5 cm (1.6 to 1.8 in).
The breeding population is estimated by Amami Ornithologists' Club (NPO, Japan) all over the island every late March since 1999.
