Coronavirus will add $2.5 billion to the cost of the Tokyo Olympics mostly for rebooking facilities, and paying additional wages for staff, as well as virus testing and cost for preventing spread of the virus. As is typical of these games going back to the disaster in spending at the Montreal Olympics that took the city years to recover, costs can double or more than double earlier estimates. Someone has to bear the extra costs and the national government will take on $1 billion of these extra costs. 

The official budget estimate was $12.6 billion. An estimate from Japan Board of Audit in 2019 came up with figure of $20 billion. The pandemic would bring this closer to $22.5 billion or close to double. This cost to the Japanese taxpayer is leading one third of people to sour on the games saying they should be canceled in mid-Nov. TV Ashai poll, with one third saying delay it, only one third for it to go ahead. Except for $5.6 billion from a privately organized committee its all coming from the City of Tokyo with some help from the Japanese government. When it comes to financing it the IOC is not taking part.
