The cost blow out was caused by unexpected payments for
building lanes on highways, as well as rising materials costs
and personnel expenses, said NHK.
The Tokyo 2020 Organizing Committee will be able to raise only
about 450 billion yen from sponsors and ticket sales, which
means a shortfall of more than 1 trillion yen, the report said.
The committee had earlier estimated a cost of 300 billion yen
for the Summer Games in 2020, but that was optimistic, said NHK.
Total costs for staging the Tokyo Olympics, estimated to be more
than 2.1 trillion yen, will be shared by the committee, the
Tokyo government and national government.
