Fourteen cases of reported melioidosis in Japan were reviewed. The mean age was 52.4 years (33–69 years), and all patients were male. All of the presumed exposures originated in Southeast Asia. The most common underlying disease was diabetes mellitus, including those patients with impaired glucose tolerance (n=8). As for mode of onset, 13 patients had acute infections and one had chronic infection. Of these 14 patients, the most common infection site on admission was lung (n=8), followed by bone (n=5), skin (n=4), gastrointestinal abscess formation (n=3), urinary tract (n=3), aorta (n=2), mediastinal lymph node swelling (n=1), and central nervous system (n=1). Bacteremia was observed in nine patients, and Burkholderia pseudomallei isolates were mostly susceptible to ceftazidime and carbapenem. Overall mortality was 14.3%. Melioidosis is a rare infection in Japan, with all known cases to date having been imported from Southeast Asia. Diabetes was a common risk factor.
