We conducted molecular phylogenetic analyses of Japanese Rhacophorus species, especially of R. schlegelii and R. arboreus from the mainland, based on samples encompassing their known distribution ranges, and discussed about evolutionary history of Rhacophorus species within Japan. The common ancestor of Japanese Rhacophorus, except for R. owstoni from southern Ryukyus, was estimated to have diverged from a lineage occurring mainly in China about 7 MYBP. Both R. schlegelii and R. arboreus are genetically largely divergent between regions of eastern and western Japan, and this seems to have been promoted mainly by retreat to refugia. Retreats of the two species to different refugia sometimes in the past seem to have led restricted distribution of R. schlegelii in eastern and R. arboreus in western Japan, and brought their intraspecific variation patterns in morphology and breeding habit.
