From Japan, 11 species of freshwater Nematomorpha have been described to date, but there are very few photographic documentations of any of them. This investigation describes specimens from the Lake Biwa Museum (Shiga Prefecture, Japan) and supplies the first SEM pictures and additional data for the species Chordodes fukuii Inoue, 1951, Japanese specimens of C. japonensis Inoue, 1952, and Paragordionus kawamurai Yamaguti, 1943. Two specimens likely belong to the genus Gordionus, which has not been reported from Japan before, but they could not be determined to the species level. Several specimens belonging to the genus Gordius could not be assigned to a certain species. This is due to general problems with the status of several Gordius species arising from the scarcity of taxonomically relevant characters.
