It breeds in Japan, Korea, and in parts of north eastern China and the Russian Far East.

The male is deep cobalt blue, with black on the face down to the upper part of the breast and flanks, the rest of the underside white.

[8] Blue-and-white flycatchers breed in primary and secondary lowland and submontane forests (including taiga, wooded slopes, and gullies) up to 1200m, and also in riverine thickets and plantations.

The nests, constructed primarily of moss, are typically situated in a variety of sheltered locations, including crevices in cliffs, among tree roots, under overhanging stream banks, in shallow tree hollows, and, rarely, within abandoned buildings.

[15] Although the species population is decreasing, its wide distribution and likely large size lead to its classification as "Least Concern" on the IUCN Red List.
