Japan's new Prime Minister Shinzo Abe Tuesday promised his personal support for Tokyo's bid to host its first Summer Olympics since his grandfather helped the capital win the 1964 Games.

Abe met Tokyo's bid leaders the day after they submitted their 2020 Games candidature file to the International Olympic Committee. Tokyo's plan features a "compact" and "dynamic" Olympics based on its financial wealth and track record in hosting international sports events. It also aims to allay fears of damage from a big earthquake or radiation from the 2011 Fukushima nuclear disaster.

"It is extremely important for the national government... to continue in our aspiration to further promote Japan as a sports nation," Abe told a delegation from the Tokyo bid committee. Abe, a former archer who heads the national archery federation, became the committee's supreme adviser on Tuesday.

"On a more personal level, my grandfather, Nobusuke Kishi, led the Tokyo 1964 bid to bring the first ever Games to Japan," said Abe, adding he was eager to cooperate in promoting the bid. The senior Abe was prime minister from 1957-1960 and also the supreme adviser to Tokyo's successful bid for Asia's first Olympics.

The premier said he would consider hosting an inspection tour in March by the IOC commission evaluating candidate cities. He may attend an IOC assembly on September 7 in Buenos Aires when it chooses the 2020 Olympic venue from among Tokyo, Istanbul and Madrid.

Japanese Olympic Committee president Tsunekazu Takeda told reporters Tokyo can host "safe and steadfast Games in one of the safest cities in the world". He said the city had set aside $4.5 billion as a reserve to complete the infrastructure. According to the candidature file, four of the 37 venues will be for football matches in other regions.

Iincluding Miyagi which is recovering from the March 2011 quake and tsunami disaster which sparked the Fukushima meltdowns. Of the 33 other venues, 28 will be within eight kilometres (five miles) of a projected Olympic village. One is an 80,000-seat stadium to be built on the grounds of the National Stadium, the main 1964 Olympics venue, at an estimated cost of 130 billion yen ($1.48 billion).

Tokyo governor Naoki Inose said a 2020 Olympics could be an "opportunity to thank the world for its support to areas hit by the disaster and help the disaster zone recover". The file said radiation in Tokyo's air had been "far below" international safety levels and strict anti-quake safety standards would guarantee no major damage to buildings, as shown in 2011.

Tokyo lost out to Rio de Janeiro in the race for the 2016 Games with low public support cited as one of the reasons for the defeat. But a survey of 800 people by the bid committee in Tokyo showed 65 percent support in October, according to the file.
