Tokyo's bid for the 2020 Olympic Games was helping to heal the wounds left by the massive quake and tsunami that killed nearly 19,000 people in Japan last year, the bid leader Tsunekazu Takeda said.
The 65-year-old - elected to the International Olympic Committee (IOC) prior to the London Olympics this year - added that the economic spin-off from winning the right to host the Games would also have a hugely positive effect on the country.
"This bid is a vivid demonstration of the power of sport with athletes and sport playing a key role at the heart of society after a difficult time," Takeda said.
"The bid process - and ultimately having the chance to host the Games - is helping Japan heal and re-unite after a difficult 2011.
"Without a doubt, Tohoku [the region affected by the tsunami], and the rest of Japan, will benefit from the Games. According to calculations provided by the city of Tokyo, the economic effect on the nation as a whole is estimated to amount to US$38 billion.
"Even when the cost of hosting the Games is taken into account, being named host city will have a net positive impact on the Japanese economy.
"The studies conducted by the Tokyo 2020 Olympic and Paralympic bid committee, in co-operation with the Mitsubishi Research Institute, show that the Games would create more than 150,000 jobs nationwide." Takeda, like his late father Prince Tsuneyoshi Takeda, was an accomplished showjumper.
He said that while many might see Tokyo as the front runner for the three-runner race - Istanbul and Madrid are the other candidates - he had little time for such tags.
"Bidding for the Olympic and Paralympic Games is no mere event," he said.
"We believe that each of the cities bidding to host the Games is incredibly motivated and has some very interesting concepts.
"I'm not interested in whether Tokyo is today's front runner. I want Tokyo to be tomorrow's winner."
Takeda, who along with his team will learn their fate at the vote of the IOC members in Buenos Aires on September 7 next year, believes this Tokyo bid has learnt from the previous one, which came third to Rio de Janeiro for the 2016 edition. "Tokyo 2020 is an enhanced bid - we have kept the best and improved the rest.
"We have revised our plans in a number of key areas - the main stadium, new village location and better use of transportation and other infrastructures.
"We have a new committee, a new team and new plans."
On that note Takeda, who is the great grandson of Emperor Meiji who ruled Japan from 1867-1912, said despite the recent resignation of the charismatic and unpredictable Shintaro Ishihara as governor of Tokyo, the bid retained support at local level.
"Despite Shintaro Ishihara's resignation, we are confident that the Tokyo metropolitan government will continue providing support for the bid and that Ishihara's resignation will have no impact on our campaign."
Takeda, who said Tokyo would be a safe pair of hands for the Games, said he was delighted with the campaign so far.
"We have an incredible campaign and a great story to tell," said Takeda, who first got inspired by the Games when he attended the 1964 renewal in Tokyo.
"While we are, of course, respecting IOC's guidelines regarding limits on international communications, we are actively preparing ourselves for a global launch in January next year."
