as of January 2016
Vaccination requisite is based on the animal health requirement agreed upon between the government authorities of each country and the Japanese Government. Export quarantine requirements prior to the departure from the country, should also be ascertained in advance from your respective Government Departments and you should follow their instructions for the necessary vaccinations since certain countries require particular re-entry procedures.
Although the JRA will be pleased to respond to any inquiries you might have on this topic, please also ask your country’s government for the latest information.
Equine Viral Arteritis Vaccination
In the case whereby a horse tests positive for antibodies of Equine Viral Arteritis (EVA), that horse will not be able to enter Japan. Therefore, please DO NOT vaccinate against EVA.
West Nile Virus (WNV) Vaccination
This is especially important for American horses, and European horses planning to come to Japan directly after running in the United States. The conditions for each of these horses are different based on the areas which they have visited or transited, the length of these visits and so forth. Please take a look at the following requirements.
Any horse which, during the last 60 days, has been in an area which has had an outbreak of West Nile Virus (WNV), must be vaccinated against that virus, or must be certified under the conditions set forth by the Government of Japan, prior to entering Japan.
Japanese Encephalitis Virus Vaccination
Aside from the requirement established by government, the JRA strongly recommends that the foreign trained horses which participate in the races held in our jurisdiction during July to October to be vaccinated against Japanese Encephalitis (JE) virus with an acceptable inactivated vaccine before coming to Japan. The JRA does not take any responsibility for any horses coming to Japan during this period without being inoculated with the necessary vaccine protection from JE. Although it is also possible for the JRA to provide the vaccine required for inoculation prior to the horse coming to Japan, owners should ask the respective authorities in their own country about import procedures and permission for use of the vaccine overseas.
It is important that all vaccinations a horse has been administered must be recorded in its passport. The JRA's veterinarian judges whether a horse is vaccinated or not only through the description in the passport.
Therefore, please ensure that all the records are completely written in the passport especially immediately after vaccination.
