Japanese talpid moles exhibit a remarkable degree of species richness and geographic complexity, and as such, have attracted much research interest by morphologists, cytogeneticists, and molecular phylogeneticists. However, a consensus hypothesis pertaining to the evolutionary history and biogeography of this group remains elusive. Recent phylogenetic studies utilizing nucleotide sequences have provided reasonably consistent branching patterns for Japanese talpids, but have generally suffered from a lack of closely related South-East Asian species for sound biogeographic interpretations. As an initial step in achieving this goal, we constructed phylogenetic trees using publicly accessible mitochondrial and nuclear sequences from seven Japanese taxa, and those of related insular and continental species for which nucleotide data is available. The resultant trees support the view that four lineages (<i>Euroscaptor mizura</i>, <i>Mogera tokuade</i> species group [<i>M. tokudae</i> and <i>M. etigo</i>], <i>M. imaizumii</i>, and <i>M. wogura</i>) migrated separately, and in this order, from the continental Asian mainland to Japan. The close relationship of <i>M. tokudae</i> and <i>M. etigo</i> suggests these lineages diverged recently through a vicariant event between Sado Island and Echigo plain. The origin of the two endemic lineages of Japanese shrew-moles, <i>Urotrichus talpoides </i>and <i>Dymecodon pilirostris</i>, remains ambiguous. Further analyses on intra-species diversity are necessary to fully solve the evolutionary histories of Japanese moles and shrew-moles.<br>
