Olympics chief Thomas Bach revealed "doubts" and "sleepless nights" over the postponed Tokyo Games on Tuesday as the opening ceremony nears after a year's delay and coronavirus chaos that has made them deeply unpopular with the Japanese public. Bach, speaking at the International Olympic Committee session in Tokyo, said the unprecedented step of postponing the Games "weighed on me" as it proved more complicated than he thought. The build-up to Friday's opening ceremony has been exceptionally rocky, with Tokyo still under a state of emergency and public opinion consistently against the Games, which will be held largely without spectators.
"Over the past 15 months we had to take many decisions on very uncertain grounds. We had doubts every day. We deliberated and discussed. There were sleepless nights," said Bach.
"This also weighed on us, it weighed on me. But in order to arrive at this day today we had to give confidence, had to show a way out of this crisis," he added.
Bach has drawn scattered protests during his visit to Japan, where the latest poll in the Asahi Shimbun newspaper showed 55 percent of respondents oppose holding the Games now.
Five people have tested positive in the Olympic Village, heightening fears that the influx of thousands of athletes, officials and media will add to a spike in cases in Japan.
The latest case in the complex, Czech beach volleyball coach Simon Nausch, came a day after one of his players also tested positive.
'Dark tunnel'
Olympic and Japanese officials have staunchly defended the Games, which are being held in a strict biosecure "bubble" with daily testing. About 80 percent of athletes have been vaccinated.
"We can finally see at the end of the dark tunnel," said Bach, adding: "Cancellation was never an option for us. The IOC never abandons the athletes... we did it for the athletes."
Delegates unanimously approved an update of the Olympic motto, "Faster, Higher, Stronger", to "Faster, Higher, Stronger -- Together", to reflect global solidarity during the pandemic.
"We see everywhere the collaborative effort bringing faster and better solutions than working in silos," said Bach.
Ski mountaineering, where competitors race up a mountain on foot and ski down it, was also approved as a new sport for the 2026 Winter Olympics in Milan-Cortina.
The changes were waved through at an unusual IOC session, where mask-wearing delegates sat socially distanced at individual desks and the podium microphone was wiped after each speaker.
On Wednesday, World Health Organisation chief Tedros Adhanom Ghebreyesus will make a keynote address, and preferred bidder Brisbane -- the sole candidate -- is expected to be handed the 2032 Summer Games.
"This is not a done deal because it's still up to the session to decide," insisted IOC communications director Mark Adams.
"They can decide to put the issue back in the pot -- there are still a number of interested cities."
The session precedes an Olympics which will mainly take place in empty stadiums to the sound of recorded crowd noises, starting with the opening ceremony in the 68,000-capacity Olympic Stadium.
The ceremony will go ahead without its planned opening music after composer Keigo 'Cornelius' Oyamada quit following an outcry over past interviews where he described bullying disabled schoolmates.
Major sponsor Toyota, the world's biggest carmaker, also scrapped plans to run an Olympic-linked brand campaign in Japan, as a top official said the Games lacked "understanding" from the public.
Japan's Emperor Naruhito will attend the opening ceremony, but an official from the Imperial Household Agency said it was not known if he will speak at the event.
