Please look at the list of the countries that have the visa exemption agreement with Japan. If your country is included in the list, you usually do not need to apply for an entry visa to Japan.
If your country is not included in the list, you need to obtain a short-term stay visa (“tanki-shouyou visa” in Japanese) from the embassy of Japan in your country.
Read carefully the Japanese visa guide provided by the ministry of foreign affairs. For entry into Japan, a VISA may be required for attendees from some countries. Please make sure whether you need to apply for a VISA or not on the web site of Ministry of Foreign Affairs of Japan at : http://www.mofa.go.jp/j_info/visit/visa/index.html.
Referring to the current COVID-19 pandemic and thus pervasive travel restrictions, please inquiry your local Japan consulate to get the latest visa application requests.
Important information regarding invitation letters (please read):
Please note AMMM conference and the organizing committees of the conference are not authorized to assist with the VISA process beyond providing the Notification of Invitation Letter issued by AMMM conference and conference Committee Board. Should your application be denied, AMMM conference and the organizing committees of the conference cannot change the decision of the Ministry of Foreign Affairs, nor will AMMM conference and the organizing committees of the conference engage in discussion or correspondence with the MOFA or the Embassy on behalf of the applicant.
It takes time for the Embassy to process the VISA application. So please register as early as you can to make sure you have enough time.
