Abstract: Based on statistical data from 22 prefectures in southwestern Japan, the relationships of the incidence of Japanese encephalitis (JE) to the density of swine farms and the area of paddy fields were analyzed, especially in relation to cattle-breeding farms during the 1960s. Large epidemics of JE often occurred in prefectures in which the total density of cattle and horse breeding farms was markedly above the density of swine farms, even when the density of swine farms was low and the area of paddy fields was less-developed. In prefectures in which the total density of cattle and horse breeding farms was relatively low, the incidence of JE correlated with the density of swine farms only in prefectures with fully-developed paddy fields. The reasons for these differences among the prefectures are discussed.
