It has black bands on the head and breast, and the sexes have similar coloration.
Along the Yamakuni River, it runs over gravel bars and walks through shallow water while searching for insects and other small prey.
In the 1987–1994 study on the Toki River in Saitama, nests were shallow scrapes in gravel lined with small stones and dry vegetation. Most clutches had four eggs, and both parents shared incubation and early brooding.
In the Toki River study, chicks left the nest within hours, following their parents and feeding themselves. They gained flight ability at about 40 days and then dispersed from the territory.
The iris is dark brown, with yellow bare skin around the eye. This yellow area is less conspicuous than in the Little Ringed Plover.
