The president of the Tokyo Olympic organising committee said on Friday that a visit to Japan this month by International Olympic Committee (IOC) president Thomas Bach seemed unlikely with a state of emergency order being extended by the government to Tokyo and other areas until May 31.

Cancelling the trip could be embarrassing for the IOC and local organisers, who say they can hold a “safe and secure” Olympics in the middle of a pandemic as cases surge in Japan — particularly in Tokyo and Japan’s second metropolis of Osaka.

The postponed Olympics are to open in only 11 weeks, on July 23, followed by the Paralympics on August 24. They will involve 15,000 athletes and tens of thousands of others entering Japan, which has reported about 10,500 deaths from Covid-19.

“Frankly speaking, I personally think it would be quite tough for him to come now,” organising committee president Seiko Hashimoto said at a weekly briefing, adding that “nothing had been decided”. “But the extension of the state of emergency and having him visit during that time will mean that president Bach will be visiting in quite a difficult time,” Hashimoto said.

“I think that would be a very difficult thing for him.”

Bach said recently he hoped to go to Hiroshima to meet the torch relay — and presumably to Tokyo — on May 17 and 18. But he has said his plans were not finalised. Coincidentally, powerful IOC member Sebastian Coe is in Tokyo for a track and field test event on Sunday at the new $1.4 billion national stadium.

Coe is the president of World Athletics, the governing body of track and field, and was also the head of the 2012 London Olympics. He is seen as a potential successor to Bach when the German’s term ends in 2025, and is also a two-time Olympic gold medallist in the 1,500 metres.

Coe has been laudatory about a half marathon test event run earlier this week in Sapporo. He’s also sympathetic with Hashimoto trying to pull off the Olympics.

“I know the pressure that you are under,” Coe said to Hashimoto. “But mercifully in London, we didn’t have the added complexity of worrying about protocols around a pandemic. So you have our sympathy in that extra tier of complexity.”

Coe also met with Tokyo governor Yuriko Koike as both try to provide assurances that the Olympics will be safe. Some scientists have suggested otherwise.

Tokyo organisers are talking up a six-day diving test event that ended on Friday. There was only one positive Covid-19 test among 438 participants — including 224 divers from 46 countries and territories. The positive test was for a team official, who was placed in quarantine, officials said.
