An aircraft that landed around 8.30 a.m. carried more than 100 Olympic delegates from the Netherlands, India and elsewhere.

The teams disembarked after other passengers, and emerged in the terminal with masks on.

As the coronavirus spreads through the capital, officials are requiring Olympic delegates to observe a so-called "bubble" to avoid contact with members of the public.

The new arrivals are first directed to a coronavirus antigen test site. Those who test negative will head for their pre-Olympic training camps or the Athletes' Village in Tokyo.

Questions have been raised about the feasibility of completely separating Olympic delegates and the public. There have already been cases in which the two parties have mixed.

Meanwhile, a Ugandan athlete who went missing from a pre-Games training camp in Izumisano city, Osaka Prefecture, has left a note. Julius Ssekitoleko, a 20-year-old weightlifter, stated his wish to stay and work in Japan. He says he finds it difficult to make a living in his home country.

Ssekitoleko was found to have bought a ticket for a shinkansen bullet train at a station in Osaka.

He went missing on Friday from his team hotel in Izumisano and has since remained unaccounted for.

City officials say Ssekitoleko was scheduled to leave Japan on Tuesday after he missed out on a spot for the Olympics.
