An account is given of 32 species identified in a small collection of hydroids originating from the Okinawa Islands. While most species are well-known from Japanese waters, three new species and five new records for Japan were encountered. Some less well known species are redescribed. Taxonomically important features of nearly all species are depicted. The new species are: Schizotricha longinema new spec., Cladocarpus unilateralis new spec., and Macrorynchia crestata new spec. Zygophylax pacifica Stechow, 1920 is recognized as a new synonym of Zygophylax cyathifera (Allman, 1888). New records for Japanese waters are: Lytocarpia delicatula, Macrorhynchia fulva, Caminothujaria molukkana , Zygophylax rufa, Thyroscyphus fruticosus. The presence of Zygophylax cervicornis in Japanese waters is confirmed through new, fertile material.
