Foreign spectators have been banned from the Tokyo Olympics forcing organisers to refund about one million tickets.
Japan is on the back of its third wave of the virus and are currently in a State of Emergency covering 30 million people.
"Based on the present situation of the pandemic, it is highly unlikely that entry into Japan will be guaranteed this summer for people from overseas," organisers said in a statement.
"In order to give clarity to ticket holders living overseas and to enable them to adjust their travel plans at this stage, the parties on the Japanese side have come to the conclusion that they will not be able to enter into Japan at the time of the Olympic and Paralympic Games.
"This conclusion will further contribute to ensure safe and secure games for all participants and the Japanese public."
The Olympic Games, which were delayed last year due to the coronavirus pandemic, are now scheduled to run from July 23 to August 8, and the Paralympics from August 24 to September 5.
