VISA Information for PRUAC Participants
Participants are advised to first check whether they need a visa to enter Japan based on the citizenship/passport they hold, rather than their country of residence.
Japan has visa exemption arrangements with a number of countries and regions for short-term stays. Participants who hold a passport issued by a visa-exempt country or region may not need to apply for a visa in advance for short-term visits to Japan, including conference participation, provided that they do not engage in paid activities in Japan.
Please note that the JAPAN eVISA system indicates eligibility mainly based on the applicant’s country or region of residence. This should not be confused with visa exemption based on citizenship. If your citizenship is covered by Japan’s visa exemption arrangements, you may not need to apply through the eVISA system.
Participants who do require a visa should check the website of the Japanese Embassy or Consulate-General with jurisdiction over their place of residence. Please also note that the JAPAN eVISA system may not be applicable for travel to Japan for the purpose of attending a conference or business-related activities. We therefore recommend that participants confirm the appropriate procedure with the relevant Japanese diplomatic mission as early as possible.
For the latest official information, please refer to the Ministry of Foreign Affairs of Japan website.
