The diatom flora of Kojorougaike Pond, located in the Hira Mountain Range in west-, central Honshu, Japan, was studied in April 2004. Diatoms were collectedfrom five different substrates, including dead monocotyledonous leaves, dead and living Sphagnum, mud and peat. A total of 38 diatom species belonging to 19 genera were identified and illustrated together with three unidentified species. The predominant genera were Pinnularia and Eunotia, represented by ten and seven species, respectively. While Pinnularia schoenfelderi Krammer was dominant on living Sphagnum, Kobayasiella micropunctata (H. Germ. )Lange-Bert. was dominant on dead ones. On the other substrata, Eunotia rhomboidea Hust. and Eunotia curvata (Kütz. ) Lagerst. were dominant.
