The prevalence of Dirofilaria immitis in cats in Japan has been examined since 1957. Twenty surveys involving a total of 3775 cats, conducted in two islands of Japan (Honshu and Kyushu), were studied. The surveys evaluated both stray (3617) and house (158) cats. Presence of D. immitis was detected at necropsy. The results show a prevalence of D. immitis varying from 0.5 to 9.5% for stray cats and from 3.0 to 5.2% for house cats on the two islands.
