The female is brown above and has a white throat, breast and belly, washed with rusty orange on the flanks and black spots. The Japanese thrush feeds on the ground, scratching through leaf-litter to find insects and earthworms. It will also take fruit. It lays 2-5 eggs in a nest made of twigs and moss, bound with mud and lined with hair and rootlets. The eggs are incubated for 12–13 days and the chick nestling period is 14 days. The species double broods (raising two broods a season), with the female laying a new clutch soon after the first brood fledges.
