We report new records from Japan for four species of freshwater Nematomorpha (Gordiida). Two species closely, but not exactly, resemble known species and were determined as Gordionus cf. lineatus (Leidy, 1851) and Parachordodes cf. okadai Inoue, 1955. The other two species are Chordodes japonensis Inoue, 1952 and Gordionus chinensis (Villot, 1874). All specimens were identified using scanning electron microscopy, with images given for Gordionus cf. lineatus and Parachordodes cf. okadai.
