The study of a collection of Japanese Syllidae (Polychaeta) from 18 different intertidal samples yielded a total of 16 genera and 31 species. Three new species of Syllis Lamarck, 1818 from Japan are described. Syllis multiannulata sp. nov. is mainly characterised by its cylindrical broad body with annulated segments, weakly articulated antennae and cirri, dorsal cirri originating from two different levels, the presence of pre- and postchaetal parapodial lobes and the pharynx being shorter than the proventricle. Syllis pilosa sp. nov. is characterised by the presence of two marked ciliary bands per segment, elongated bidentate compound chaetae, and a very long pharynx and proventricle. Syllis rubicunda sp. nov. has a broad cylindrical body with distinct colour pattern, long and thick dorsal cirri, bidentate chaetae, and the pharyngeal tooth slightly removed from the anterior margin. Two species, revealing previously unreported morphological features, are also described and illustrated (Amblyosyllis speciosa Izuka, 1912 and Odontosyllis undecimdonta Imajima and Hartman, 1964). Moreover, one species belonging to the genus Pionosyllis Malmgren, 1867, is described, but with remain unnamed until additional material becomes available. An emended diagnosis for Alcyonosyllis Glasby and Watson, 2001 and a new combination, Alcyonosyllis exiliformis comb. nov. are proposed. The generic name, Tryponciseta, Imajima and Hartman, 1964 is proposed to replace Geminosyllis, Imajima, 1966 and the species, Tryponoseto sp. is described. Additionally, four new species to Japanese waters are herein reported: Eusyllis assimilis Marenzeker, 1867, Nudisyllis tinihekea Knox and Cameron, 1970, Paroehlersia ehlersiaformis (Augener, 1913), Branchiosyllis exilis (Gravier, 1900) and Syllis armillaris (MOller, 1771). Finally, Eusyllis hobei Imajima 1966 and Odontosyllis fulgurans japonica Imajima, 1966 are considered synonymous with E. lamelligero Marion and Bobretzky, 1875 and O. fulgurons (Audouin & Milne Edwards, 1833) respectively.
