Currently, entry into Japan is restricted. In order to enter Japan, you must apply for entry and receive a permit from the Japanese government.
It is expected to take more than a month from you start the application process until the permit is granted, so please complete the application process by mid-December.
If there is no one responsible for the application, you can apply through our Japanese partner Crisis Intelligence.
If there is a delay in applying for entry, there is a possibility that the VISA will not be issued in time.
