Three species of Bagous are described as new from Japan, B. yamazakii O'Brien & Morimoto, B. fractodes O'Brien & Morimoto, and B. nipponensis O'Brien & Morimoto. Bagous yamazakii, known only from males, possibly represents an entirely new species group, but probably is related to the B. hydrillae group, the species of which are in Australia. Bagous fractodes, known only from a single male, is similar to B. fractus of Japan, but evidently is not closely related to it. Bagous nipponensis is known only from a single female; it is clearly not any species hitherto known from Japan, but its phylogenetic position is equivocal. The key to Japanese species is modified to include these three new species. Habitus photographs and line illustrations of genitalia are provided.
