Large sections of the Japanese population have expressed opposition to Tokyo 2020 taking place in the build-up to the Games, scheduled to open on July 23.

The recent rise in COVID-19 cases in the capital forced the Government to declare a fourth state of emergency, which will be in place throughout the Games and led to the decision to ban spectators from almost every venue.

Bach's arrival here last week was greeted with angry messages on Twitter and the phrase "go home Bach" was briefly trending on Twitter.

The IOC and Tokyo 2020 have implemented a series of rules they hope will ensure the Games, due to last until August 8, will be "safe and secure".

They include banning all participants from tourist areas such as bars and restaurants, and telling athletes to arrive no earlier than five days before their competition and depart no later than two days later.

The IOC has also struck vaccination deals in an effort to get as many athletes, officials and delegation members jabbed in time for the Games, while competitors will be subjected to daily COVID-19 testing.

The measures have already been criticised for being too lax and insufficient by the first Chinese delegation to arrive in Japan.

"The IOC is standing at your side, we are sitting in one boat and we are rowing together with full force in the same direction," Bach told Tokyo 2020 President Seiko Hashimoto prior to an in-person meeting today.

"Our common target is a safe and secure Games for everybody, for all the athletes, delegations and the Japanese people.

"The Japanese people can have confidence in all of the efforts we are undertaking to make them secure and safe, with all the most intensive and strict COVID measures and the vaccination programme we have been undertaking worldwide."

Bach had accidentally referred to "Chinese people" before catching his mistake.

Today marked the official opening of the Olympic Village in Tokyo, where the majority of competitors at the Games will reside during the event.

"Now it is 10 days to the opening, that also means there is still a lot of work to do," Bach said.

"Our task is only completed once the athletes have left Tokyo.

"Today the Village is opening and the athletes are entering it.

"I think we also feel like athletes...we have done and you have done a fantastic job in preparing for the Games.

"You can be confident that the stage is set but now the task is to perform, to deliver and show your best of what you have been preparing for for such a long time.

"Let’s continue to work like, and for, athletes to make the Games a resounding success for Japan, for Tokyo and for the entire Olympic Movement."

Hashimoto, who replaced predecessor Yoshirō Mori in February after he resigned following uproar at derogatory comments he made about women, admitted that Tokyo 2020 "knows there are various issues and challenges, but in good and solid unity we are finding and making solutions to these issues".
