Tokyo held a send-off rally for the city's bid committee ahead of the IOC vote next month in Argentina, as competition heats up in the race between three cities hoping to stage the 2020 Summer Olympics.
Japanese Prime Minister Shinzo Abe attended the rally, and was joined by more than 800 supporters from business and industry - as well as government officials.
The IOC vote, scheduled to take place in Buenos Aires on September 7th, will be attended by Abe, Governor of Tokyo Naoki Inose, as well as a number of Japanese athletes who have won medals in previous Olympic Games.
Tokyo has underlined its bid with promises of financial stability, a reliable infrastructure and a compact venue, but the latest radioactive leak at the damaged Fukushima nuclear power plant has not helped increase optimism.
Inose insisted on Friday that the incident will not affect Tokyo's bid to host the 2020 Olympics.
The city faces stiff competition from two rivals - Madrid and Istanbul.
