Populations from northern Taiwan and the Yaeyama Islands were isolated as a new species(Buergeria choui) in 2020.

[2] Buergeria japonica is a common species that occurs in a wide variety of habitats (rivers, intermittent rivers, freshwater marshes, intermittent freshwater marshes, freshwater springs, geothermal wetlands, irrigated land, and canals and ditches).

[1] Buergeria japonica is a small to medium-sized frog, about 3 cm (1.2 in) snout-vent length in males.

[3] Buergeria japonica normally breed in slow-moving water in ditches and small streams.

Another advantage is that high temperature facilitates growth; furthermore, competition may be reduced in this unusual habitat.
