Tokyo on Tuesday welcomed as "highly positive" an IOC report about bids for the 2020 Summer Olympics which highlighted its ability to host safe and compact Games on solid financial strength.
The International Olympic Committee evaluation commission issued the report after touring Tokyo, Madrid and Istanbul in March, assessing each city's bid for the Games.
"I am extremely pleased with the report," Tsunekazu Takeda, president of the Tokyo bid committee and the Japanese Olympic Committee, said.
"We will continue to study the highly positive report closely and review any areas we can make additional improvements as we prepare to host a superb Games in 2020," he said in a statement.
Tokyo is the only one among the three cities to have previously hosted the Olympics, in 1964.
The report could help the IOC's 100 members choose the 2020 host among the cities when they vote in Buenos Aires on September 7.
The report said Tokyo "seeks to deliver well-organised and safe Games that would unite world-class innovation with traditional values under the motto of 'Discover Tomorrow'".
It also noted the teeming Japanese capital plans to have 85 percent of competition venues within an eight-kilometre (five-mile) radius of the projected Olympic village to host a compact and "unique celebration in the centre of the city".
The city's reserve fund of $4.5 billion for hosting a Games was also cited as one of its financial strong points.
Tokyo Governor Naoki Inose said that he was "extremely happy to learn that Tokyo's compact venue plan, quick and reliable transportation system, first-class accommodation, strong financial base, solid security system, and strong hosting ability were rated high by the Evaluation Commission members".
The IOC report said all three bids were of a high quality, adding that it had not taken into account any information received after the commission's inspection tour.
Istanbul has been embroiled in fierce anti-government protests in recent months while financial concerns have gripped Spain whose capital is Madrid.
On the fear of natural disasters following the devastating 2011 earthquake and tsunami in Japan, the report said that "robust" anti-quake construction standards and necessary anti-tsunami safety measures were in place.
