National delegations have also been able to enter the Village to prepare for the arrival of their respective athletes.

Athletes were dropped off and entered the Village at a location inaccessible to the media.

The low-key nature of the arrivals was underlined by traditional welcome ceremonies for teams being cancelled.

Tokyo 2020 claimed the cancellation of the media opportunities and welcome ceremonies came as part of simplification measures due to the COVID-19 pandemic.

"The athletes are grateful that these Olympic Games are happening under these circumstances, and that all measures are being taken to deliver safe and secure Games," International Olympic Committee President Thomas Bach said.

"After all that they had to overcome during this last year - where they did not know whether the next competition would take place, they did not know whether they could go to training the next day, they did not know where they would meet with their coach again - after all this additional stress during the pandemic, finally they can shine on the Olympic stage.

"And I hope that they will, under these circumstances nevertheless, enjoy it to the fullest."

The Village is located at the Harumi waterfront district of Tokyo, around six kilometres from the National Stadium.

The complex features 21 residential buildings and 3,800 condos.

Around 18,000 athletes and officials are expected to stay at the Village during the Olympics.

Athletes have been instructed to arrive no earlier five days prior to their competition and leave no later than two days after their event concludes.

The restrictions are part of measures designed to reduce the risk of spreading COVID-19, although organisers are yet to confirm what the expected capacity of the Olympic Village will be during the Games.

The IOC claim around 85 per cent of participants arriving in the Village will have been vaccinated against COVID-19.

The Village Plaza is set to serve as a social hub for athletes and will include a cafe, florist, bank, photo studio and dry cleaners,

A Tokyo 2020 merchandise shop is also included in the complex.

A fitness centre, a recreation centre, the doping control station and a polyclinic are also included at the Olympic Village.

The Czech Olympic Committee were among the first nations to begin preparations for their athletes, with their canoe slalom athletes set to arrive later this week.

"We already have a completely decorated background with common areas, where athletes will be able to watch television broadcasts, but also play darts," Martin Doktor, the Czech Republic's Chef de Mission, said. 

"Or table tennis on a cardboard table, which we chose because the beds are made of the same material. 

"Of course, there is also a coffee machine in the kitchen."

Doktor revealed that decorations at their part of the Village honoured Věra Čáslavská, winner of three Olympic gymnastics gold medals at Tokyo 1964. 

The Olympic Village has opened a day after Tokyo officially entered into a fourth state of emergency.

An increase in new COVID-19 cases and concerns over new variants led to the decision to place the capital back in a state of emergency.

The Japanese Government admitted it was hoping to restrict people travelling during the summer break and the Bon holidays until vaccinations rose further.

Japan reported over 2,400 new COVID-19 cases yesterday, with 502 reported in Tokyo.

Nearly 62 million vaccine doses have been administered in Japan to date, a rise of 1.7 million from yesterday’s figure.

A total of 44 million elderly people have received doses, with 27.4 million receiving one dose and 17.2 million both doses.

The figure means 77 per cent of elderly people have received a single dose, with nearly half having been fully vaccinated.

In the overall population 30.3 per cent have received one dose, with 18.5 per cent now fully vaccinated.
