Tokyo-Japanese Prime Minister Taro Aso pledged his government's full support for Tokyo's bid to host the 2016 Games as a delegation from the International Olympics Committee began an inspection Thursday.

"It is my earnest desire to invite young Olympians from around the world to Tokyo to experience what I felt and learned as a young athlete," Aso told the 13-member IOC evaluation team.

Aso, who was a member of the Japanese shooting team at the 1976 Montreal Olympics, added: "Whatever needs to be done, will be done. Whatever needs to be built, will be built. Whatever needs to be financed, will be financed."

Tokyo officials say they are confident of promoting the city as the most appropriate venue for the 2016 Games.

"I was very nervous all day," Tokyo governor Shintaro Ishihara said at a press conference. "But many experts gathered and I was also able to answer IOC's pinpoint questions."

Japan's capital is aiming to stage the world's first carbon-minus Olympic and what it calls the most ambitious energy conservation policy for the Games. No details were revealed.

But Ishihara expressed concerns whether four days would be sufficient for the IOC to assess Tokyo's financial ability and environmental conditions.

Although the city has a central government's guarantee to finance the Games, Tokyo currently sees no need to make use of it, Ishihara has said.

The IOC evaluation team was expected to complete the inspection on Monday.

Besides Tokyo, Chicago, Madrid and Rio de Janeiro are bidding to host the summer games in 2016. (dpa)
