Diatom flora of a Sphgnum bog, Yakumogahara Moor, located in the Hira Mountain Range in west-central Honsyu, Japan, was studied. Eleven samples were collected in May 2004. A total of 50 diatom species belonging to 20 genera were identified and illustrated together with one unidentified species. Frustulia saxonica Rabenh. was the most abundant species and it was dominant in seven of the 11 samples. The predominant genera were Eunotia and Pinnularia, represented by 11 and 10 species, respectively.
