From March 1, Japan has opened its borders to all travelers
except tourists with a COR, also known as certificate of registration. CORs can be issued via the online ERFS (Entrants, Returnees, Follow-up System) to an organization in
Japan responsible for abidance to quarantine orders by the entrants.
