2020: Tokyo's bid for the 2020 Summer Olympics enjoys "strong" government, business and public support, International Olympic Committee (IOC) vice president Craig Reedie said on Thursday at the end of a four-day inspection tour.

"We have been hugely impressed by the quality of bid presentations by the bid committee. Across the board, it has been excellent in every way," the former head of the British Olympic Association told a news conference.

Reedie was heading a 14-member team from the IOC evaluation commission tasked with scrutinising bids by Tokyo, Madrid and Istanbul for the multi-billion dollar sporting extravaganza.

"We have witnessed the strong government support which the bid enjoys," Reedie said, citing the presence of Prime Minister Shinzo Abe and his ministers in some presentations.

Abe also hosted a dinner at a plush guest house near Akasaka Palace on Wednesday night for the IOC inspectors, also attended by Japanese medallists from last year's London Olympics and Paralympics.

The team will travel to Madrid on March 18 for a similar evaluation tour full of presentations and visits to existing and planned facilities for 2020, followed by another to Istanbul a week later.

It will draw up a technical report on the three bids for the 101 IOC members before they meet in Lausanne on July 3-4 to hear bid cities pitch their plans to them. The IOC will vote to choose the 2020 host on September 7 in Buenos Aires.

"We also benefited from contributions from a wide range of the Japanese business community," Reedie said.

"We've witnessed strong national support," he added, after noting his team's audience with Crown Prince Naruhito.

There was no involvement of Japan's royal family when an IOC inspection team visited Tokyo four years earlier to assess its bid for the 2016 Games which the city lost to Rio de Janeiro.

Toyota chairman Fujio Cho told the team that Japan's corporate giants are ready to chip in for another Summer Olympics in Tokyo, hoping the Games will provide the same economic boost as the 1964 edition.

Concerning the 2011 Fukushima nuclear disaster, Takeda said his committee had produced "solid data to show radiation levels (in Tokyo) are lower than international (safety) standards".

Reedie said they had asked the bid committee to report on the risks. "They are the experts and they have done so. We have noted their comments," he said.
