Tokyo 2020 organisers have estimated that a total of ¥43.74 billion (£312.37 million/$387.71 million/€365.27 million) will be required to build or upgrade 11 venues outside the Olympic and Paralympic Games host city.
According to sources of Japanese newspaper The Yomiuri Shimbun, the Organising Committee has presented the approximations to the Central and Tokyo Metropolitan Governments and the six prefectures that are home to the facilities.
The Sapporo Dome in Hokkaido and Miyagi Stadium, which will both host football events, are said to need work costing ¥2.69 billion (£19.21 million/$23.84 million/€22.46 million) and ¥2.74 billion (£19.57 million/$24.29 million/€22.88 million).
In Saitama, basketball’s Saitama Super Arena requires ¥2.94 billion (£21 million/$26.06 million/€24.55 million), while football’s Saitama Stadium 2002 requires ¥2.9 billion (£20.7 million/$25.7 million/€24.2 million), golf’s Kasumigaseki Country Club requires ¥3.95 billion (£28.21 million/$35.01 million/€32.99 million) and the GSDF Asaka Shooting Range requires ¥8.87 billion (£63.34 million/$78.62 million/€74.07 million).
Cycling’s Izu Velodrome and Izu Mountain Bike Course in Shizuoka need a combined total of ¥6.9 billion (£49.3 million/$61.2 million/€57.6 million).
Estimates for one venue each in Kanagawa and Chiba are undecided; baseball/softball’s Yokohama Stadium and surfing’s Tsurigasaki Beach respectively.
Those given for Kanagawa are ¥2.88 billion (£20.57 million/$25.53 million/€24.05 million) on sailing’s Enoshima Yacht Harbor and ¥2.54 billion (£18.14 million/$22.51 million/€21.21 million) on football’s International Stadium Yokohama.
Chiba’s Makuhari Messe, which will host fencing, wrestling and other events, requires ¥7.33 billion (£52.35 million/$64.97 million/€61.21 million).
Of the total, ¥5.2 billion (£37.1 million/$46.1 million/€43.4 million) will be used to construct or improve five permanent facilities that can be used after the Games.
Constructing temporary facilities that will be demolished after the Games will cost ¥38.54 billion. (£275.23 million/$341.62 million/€321.84 million).
Tokyo 2020 unveiled a budget of between ¥1.6 trillion (£11.4 billion/$14.2 billion/€13.4 billion) and ¥1.8 trillion (£12.9 billion/$16 billion/€15 billion) in December.
The official cost estimate, revealed during a Four-Party Political Working Group meeting, was down from the maximum budget cap of ¥2 trillion (£14.3 billion/$17.7 billion/€16.7 billion) cited by Tokyo 2020 President Yoshirō Mori in November.
Concerns have been raised by Local Governments in Japan, with reports 10 wrote to Koike in December urging her not to backtrack on a promise made by the Metropolitan Government in 2013, over the cost burden they may have to shoulder, regarding the construction of temporary facilities for the Games.
The policy said Tokyo 2020 should bear the brunt of the costs for building temporary venues.
A recommendation had been made by the task force appointed by Tokyo Governor Yuriko Koike, which warned in September that drastic changes must be taken to avoid the budget ballooning to ¥3 trillion (£21.4 billion/$26.6 billion/€25.1 billion), that the Local and Municipal Governments could help pay for temporary venues.
It was expected that the issue of dividing up the costs would be a key part of talks held between Koike and Japanese Prime Minister Shinzō Abe last month in an attempt to determine the exact share parties would be required to take up.
A decision on this is likely to be made by Abe, Koike and Mori before the end of the current fiscal year in March.
