You'll need to check the list of the countries that have the visa exemption agreement with Japan. If your country is included in the list, then you will not be required for a visa when entering Japan under normal circumstances. If your country is not included in the list, you'll need to obtain a short-term stay visa from the embassy of Japan in your country.

Please read the Japanese visa guide provided by the ministry of foreign affairs carefully. And be informed that it is the embassy of Japan in your country that makes a decision on issuing a visa. Whether the attendees need Letter of Invitation fully depends on the relations between countries. The conference organizers hereby reiterate that we are neither able to nor authorized to decide the relations between countries.

Invitation Letter
Please note the organizing committee of the conference is not authorized to assist with the VISA process beyond providing the Invitation Letter. Should your application be denied, the organizing committee of the conference cannot change the decision of the Ministry of Foreign Affairs, nor will the organizing committee engage in discussion or correspondence with the consulate or the visa center on behalf of the applicant.

The invitation letter will be issued upon request after the successful registration.

Letter of Invitation is an official document which confirms a registration payment and extends an official invitation to the paid registrant to attend and participate in the upcoming conference. It provides you with an official reason to come to Japan. It may be required for visa application if you are from a country that does not have a visa exemption agreement with Japan.

In order to qualify for a Letter of Invitation, you must meet both of the following criteria:
Be a registered author of an accepted full paper or abstract
Have paid the conference registration fee.
Letter of Guarantee is a letter in which an individual or body agrees to be legally and financially responsible for you during your stay in Japan. You may know a willing individual or institution in Japan who is willing to act as a guarantor, or, if you have no connection with the country, the Japanese Ministry of Foreign Affairs may find that it is acceptable to have your university act as the guarantor. Kindly note that the conference organizer cannot provide Letters of Guarantee.
