Japan’s Ministry of Agriculture, Forestry and Fisheries has established a policy to vaccinate pigs raised in pig farms against classical swine fever [CSF] to contain the outbreak.

CSF returned to Japan in September 2018, when confirmed after its absence for the previous 26 years. The virus was initially spreading in domestic pig farms in the Chubu region; most of the cases concentrated in Gifu, one of the 9 prefectures included in Chubu.

However, the confirmation of CSF in September 2019, in the Saitama prefecture in domestic pigs, led to the decision to apply vaccinations to domestic pigs to prevent further spread of the disease.
