Japanese spiders of the genus Dolomedes are revised and its phylogeny is inferred by mt-DNA. <I>Dolomedes japonicus</I> B&ouml;senberg & Strand 1906 and <I>D. angustivirgatus</I> Kishida 1936 are removed from the synonymy. <I>Dolomedes fimbriatoides</I> B&ouml;senberg & Strand 1906 and <I>D. hinoi</I> Kayashima 1952 are newly synonymized with <I>D. sulfureus</I> L. Koch 1878, and <I>D. stellatus</I> Kishida 1936 is synonimized with <I>D. japonicus</I>. Two new species, <I>D. fontus</I> and <I>D. silvicola</I> are described. Relative leg length and proportion of male palpal tibia are considered as good keys to indentify <I>Dolomedes</I> spiders, whose genital organs closely resemble one another. <I>Dolomedes sulfureus</I> and <I>D. silvicola</I>, often found on vegetation, have much longer legs and male palpal tibia than their relatives that inhabit near water and run on water surface or hide under water when disturbed. Molecular phylogenetic analysis using mt-COI revealed the following; ((((<I>raptor</I>, <I>yawatai</I>), <I>japonica</I>), <I>orion</I>), (((<I>angustivirgatus</I>, <I>sulfureus</I>), <I>fontus</I>), (<I>silvicola</I>, <I>saganus</I>)), <I>horishanus</I>).
