This species is endemic to the islands of Honshu, Shikoku, and Kyushu in Japan. B. buergeri inhabits mostly mountainous regions near streams or lakes.

B. buergeri is probably closely related to B. robusta of Taiwan and B. oxycephalus of the Hainan Islands because these species all have the habit of lotic-species breeding. B. buergeri feeds on small insects and spiders.
